SIMATIC PX proximity switches Portfolio overview
Totally integrated in TIA IQ-Link is a concept for the intelligent integration of sensors in automation systems. Just like all products and systems incorporated in Totally Integrated Automation, IQ-Link devices also feature the same properties with respect to communications capability, data management and configuration/programming. This provides advantages in every aspect, and not just enormous savings potential for engineering. For the first time, plant-wide communication down to the sensor level can be implemented not just extremely easily, but highly profitably as well. SIMATIC PXS sonar proximity switches Sonar proximity switches can be used as non-contact proximity switches in many fields of automation. These devices can be used whenever distances through air have to be evaluated, because they not only detect objects, but can also output and evaluate the absolute distance between the Sonar proximity switch and the object. Changing environmental conditions (e.g. temperature variations) are compensated during evaluation of the measurement. SIMATIC PXO optical proximity switches The photoelectric proximity switches react to changes in the received quantity of light. The light beam emitted from the emitter diode is interrupted or reflected by the object to be detected. Depending on the type of BERO, the interruption or reflection of the light beam is evaluated. SIMATIC PXI inductive proximity switches Inductive proximity switches are the low-cost solution for non-contact detection of metal objects. Inductive proximity switches are extremely reliable with a very high repeat accuracy and long service life thanks to nowear operation as well as their insensitivity to temperature, noise, light and water. SIMATIC PXC capacitive proximity switches Capacitive proximity switches are also non-contact sensors for measuring conducting and non-conducting materials in solid, powder or liquid state.

Intelligent proximity switches Easy to insert, simply more productive
Sensors and PLCs are growing together Sensors are becoming more intelligent and versatile. Thus setting and evaluation possibilities are increasing. Thanks to intelligent linking to the PLC, IQ-Link can now be used to implement significantly more flexibility and reliability of the sensors. The uniform exchange of data presents a great number of advantages - for plant construction as well as for its operation. Thanks to the integrated availability of parameters, for example, a setting made on a sensor can be transferred to other sensors as often as required. Central data management ensures that the sensors continue to work with the correct setting values without new parameterizing even after replacement. Furthermore, IQ-Link permits channel-specific system diagnostics. In addition to failures in wiring sensor-specific errors will be detected. Thanks to TIA all these augmented functions are available in the usual system environment without additional configuring. TIA provides this already system integrated.
New communication standard: IO-Link Well-known manufacturers of sensor and automation technologies partnered up under the roof of the PROFIBUS user organization (PNO) to develop an integrated communication standard for sensors and actuators. After completion of the specification at the beginning of 2008 together with the integration into the fieldbus level first IO-Link products will come into the market. Retaining the low-priced point-to-point wiring the goal was to create potential for further cost reductions for the user on commissioning and maintenance costs as well as plant availability. The proven IQ-Sense technology from Siemens was incorporated into the IO-Link specification. Siemens has played and will play a leading role in the creation of the new standard which additionally has been turned in as an IEC standard.

SIMATIC PXS sonar proximity switches from 2.5 cm to 10 m - they hear everything!
Sonar proximity switches SIMATIC PXS ensure non-contact sensing with millimeter precision in the range from 2.5 cm to 10 m. Principle: Sonar proximity switches transmit ultrasonic pulses; when reflected by objects or surfaces, the echoes can be received by the proximity switch and the distances calculated and converted to an output signal. Sonar proximity switches feature large sensing distances up to 10 meters, high accuracy in the millimeter range, good reproducibility and require little maintenance. Sensing is not affected by dust and contamination common in harsh industrial environments. Liquids can be sensed with the same precision as solids, granulates or powders.
Sonar proximity switches are suitable for a wide range of applications, such as level measurement, position detection, limit detection, thickness measurement and stack height measurement. Measurement of stack height
Distance monitoring Measurement of diameter and speed indicator
Size measurement Contour measurement
Loop monitoring Quality control

SIMATIC PXS sonar proximity switches Functionality and highlights
Function The sonar proximity switches only operate through the medium of air and can detect any objects that reflect ultrasound. They emit ultrasonic pulses cyclically. When an object reflects these pulses, the resulting echo is received and converted into an electrical signal. The incoming echo is detected in accordance with its intensity which, in turn, is dependent on the distance between the object and the sonar proximity switch. Sonar proximity switches operate according to the echo propagation principle, i.e. the time difference between the emitted pulse and the echo pulse is evaluated. The construction of the sensor causes the ultrasonic beam to be emitted in the shape of a cone. Temperature compensation The proximity switches of compact ranges M30 K2, M30 K3 and M18 are fitted with temperature sensors and a compensation circuit that equalizes changes in operating distances caused by temperature changes.
Highlights ■ Millimeter-accurate measurement ■ Color and material-independent, even transparent objects ■ Individual parameter setting ■ Small, compact housing ■ Very high degree of repeat accuracy ■ UL/CSA approvals ■ Sensors available for Ex Zone 2/22 ■ Insensitive to temperature, noise, light and water
Synchronization In compact ranges M30 K2, M30 K3 and M18, several devices can be synchronized with each other by simply interconnecting the synchronization outputs of the devices. Up to 10 devices can be synchronized (or 6 devices in the case of compact range 0). This allows the sensors to be mounted extremely close to each other in many cases without causing mutual interference. Programming with SONPROG · Programming the devices of the compact ranges M18, M30 K2 and M30 K3 · Possible settings include: · Operating range beginning and end · Analog range beginning and end · Switching hysteresis · Mean value generation · Multiplex mode · NO/NC contact switchover Sensors for Ex Zone 2/22 The PXS800 sonar proximity switches are approved according to EU Guideline 94/9/EG (ATEX) Appendix VIII.

SIMATIC PXO opto proximity switches Fast and accurate sensing with light and laser
The various versions of the SIMATIC PXO opto proximity switches are predominantly used in the following applications: · In conveyor systems · In packaging machines · In mechanical engineering applications · In paper, textile and plastics processing · In printing machines · For access control. These photoelectric sensors detect all objects regardless of their composition, whether metal, wood or plastic. Special versions of the K20 form in miniature enclosure and the C40 are available for detecting transparent objects. Special devices such as the color sensor or color mark sensor can be used to detect differences in color or contrast. An analog laser and also the Fibre-optic sensor support extremely precise distance measurements and position monitoring. Application of a laser distance sensor for precise distance sensing of conveyers would be appropriate. The devices can be mounted in any position. They should be installed in such a manner as to prevent dirt deposits as far as possible.

SIMATIC PXO opto proximity switches Functionality and highlight
Diffuse sensor (energetic sensor) The light from the emitter falls on an object and is reflected in a diffuse pattern. Part of this reflected light reaches the receiver located in the same device. If the intensity of the received light is sufficient, the output is switched. The sensing range depends on the size and color of the object involved as well as its surface texture. The sensing range can be varied within a wide range by means of the built-in potentiometer. The energetic sensor can therefore also be used to detect different colors.
Highlights ■ Extremely precise and quick-acting with pin-point locating ability ■ High performance even across large distances ■ Small, compact housing ■ Reliable measurement even in the smallest spaces with Mini-Sensor (K20/K21) ■ Degree of protection up to IP68
Diffuse sensor with background suppression Diffuse sensors with background suppression can detect objects up to a specific sensing range. All objects beyond this range are suppressed. The focus level can be adjusted. The background is suppressed due to the geometric constellation between the emitter and the receiver.
■ Adjustable ranges
Retroreflective sensors The light from the emitter diode is focused through a lens and directed via a polarization filter to a reflector (principle of a 3way mirror). Part of the reflected light passes through another polarization filter and reaches the receiver. The filters are selected and aligned in such a way that only the light reflected from the reflector reaches the receiver and not the light reflected from other objects within the beam range.
■ Sensing or distance measurement on large distances with laser distance sensors
Thru-beam sensors Thru-beam sensors comprise an emitter and a receiver. The emitter is aligned in such a way that the greatest possible amount of pulsed light from the emitter diode reaches the receiver. The receiver evaluates the incoming light to clearly separate it from the ambient light and other light sources. Sensors for Ex Zone 2/22 The K80 ATEX optical proximity switches are approved according to EU Guideline 94/9/EG (ATEX) Appendix VIII The approval is for:
· Gas EX II 3G EEx nA II T6 X and · Dust EX II 3D IP65 T 80 °C X The functionality of the optical proximity switches with ATEX approval is identical to that of the standard proximity switches.
■ Simple commissioning (Teach-In) ■ UL/CSA approvals ■ Version for use in Ex zone 2/22 (K80 form) ■ Precise sensing of smallest objects with fiber-optic sensors or fork sensors

SIMATIC PXI inductive proximity switches Functionality and highlights
Function A high-frequency alternating field is generated in the proximity switch and emerges at the "sensing face". The physical size of this alternating field determines the "range" of the device. When a material that is a good conductor of electricity and/or magnetism comes into close proximity with the sensing surface, the field is damped. Both states (field damped or undamped) are evaluated in the proximity switch and result in a change in the output state of the switch. Built-in protection: · Spurious switch-on pulse · Short circuit and overload (DC) · Swapped connectors · Wire-break (connection L- or L+), · Overvoltage peaks · Radio interference · Spurious signal suppression The inductive proximity switches are classified in accordance with their applications or their technical characteristics: · for standard duty · for PLCs (2-wire) · for extra electrical duty · for extreme environmental conditions (IP69 K) · with greater operating distance · without a reduction factor · pressure-resistant up to 500 bar (7250 psi) · with analog output · for use in Ex zone 2/22

SIMATIC PXC capacitive proximity switches Functionality and highlights
Function The sensing face of a capacitive sensor is formed by two concentrically arranged metal electrodes that are equivalent to the electrodes of an unwound capacitor. The electrode surfaces A and B are connected into the feedback branch of a high-frequency oscillator that is tuned such that it does not oscillate when the surface is free. When an object approaches the active face of the sensor, it enters the electric field in front of the electrode surfaces and causes a change in the coupling capacitance. The oscillator starts to oscillate; the amplitude is recorded by an evaluation circuit and converted into a switching command.
Highlights ■ Detection of all materials (e.g. plastics,wood, paper) ■ Measurement of liquid through plastic tubes or glass pipes ■ Measurement of aggressive chemicals ■ Adjustment of the operating distance on the object
Switching frequency
The build-up characteristics specific to other pulse/interval conditions may result in higher switching frequencies than those specified. Operating distance The stated values are applicable to a target of metal which is grounded and whose area corresponds to the sensing face of the proximity switch. The real operating distance sr for nonconductive targets is dependent on the relative dielectric constant er and the characteristic value (see characteristic curve).
Built-in protection: · Spurious signal suppression · Short-circuit and overload protection · Polarity reversal protection for connections · Inductive interference protection
Dielectric constants of various materials: · Glass 5 · Paper 2.3 · Vacuum, air 1 · Water 80

SIRIUS detection devices are paying attention!
Siemens also offers a wide range of mechanical sensors in addition to the non-contact proximity switches of the SIMATIC Sensors range. The new SIRIUS spectrum of detection devices ranges from position switches in different versions, through hinge switches to magnetically operated switches. Standard position switches: reliable and conforming to standards With a wide range of new features, this new generation of position switches is successfully used in virtually all applications: · Detection of hazardous movements of machine parts · Monitoring of protection equipment with rotary joints, such as swiveling doors, access flaps, lids, etc. · Monitoring of lateral-motion protection equipment, such as sliding doors, guards, etc. The dimensions, fixing points and characteristics of our position switches largely comply with EN 50041 or EN 50047. Whether in plastic or metal enclosures: we have the right switch for your specific requirements. Reduced installation time and increased flexibility can be archieved through modular construction of individual components and simple connection for plastic housing.
26
Short-stroke switches: accurate and compatible Exact switching is required when monitoring doors and access flaps. No problem for our position switches with short-stroke switching element. Position switch with separate actuator: proven and safe With their largely standardized housings and operating mechanism types, our standard position switches have been tried and tested in the monitoring of protection doors. An alternative is to use a position switch with a separate actuator. It has multiple mechanical coding to prevent easy manipulation and thus overriding of safety equipment. The switching unit is fixed to the door frame and the actuator to the protection door. In the safe state, i.e. with the protection door closed, the operating mechanism is seated snugly in the operating head of the switch and actuates the contacts, which open with positive action when the door is opened.

SIRIUS detection devices The right detection device for every application
Position switch with tumbler: clever and reliable Position switches with a separate actuator and an additional electromagnetic tumbler are used if an interlock is required on a protection door, e.g. to secure the operating area of a robot. They keep the protection door interlocked until the operating area can be entered without danger. In other words: until the machine has come to a complete standstill or a non-critical speed has been reached. An electrical signal, e.g. from a safe zero-speed monitor, then actuates the interlock solenoid and releases the protection door. Position switches have a greater degree of security through locking pressure of up to 2600 N in the metal version and up to 1300 N in the plastic version even in harsh working environments.
Magnetically operated switches: Compact and secure against manipulation Magnetically operated switches are contactless and are especially suitable for monitoring protection doors. The reed contacts in the switching element are actuated by a coded switching magnet and are thus particularly tamper-proof. The members of our 3SE6 family of magnetically operated switches, in conjunction with ASIsafe 3RK modules and 3TK28 electronic safety modules, are approved up to Cat. 4 in conformity with EN 954-1.
Hinge switches: Easy to mount Our range of hinge switches completes the spectrum of position switches for monitoring swiveling doors and flaps. These mechanical switches provide maximum protection against tampering and manipulation thanks to the snug connection between the switch and the protection door hinge.

SIMATIC PX proximity switches Portfolio overview
Totally integrated in TIA IQ-Link is a concept for the intelligent integration of sensors in automation systems. Just like all products and systems incorporated in Totally Integrated Automation, IQ-Link devices also feature the same properties with respect to communications capability, data management and configuration/programming. This provides advantages in every aspect, and not just enormous savings potential for engineering. For the first time, plant-wide communication down to the sensor level can be implemented not just extremely easily, but highly profitably as well. SIMATIC PXS sonar proximity switches Sonar proximity switches can be used as non-contact proximity switches in many fields of automation. These devices can be used whenever distances through air have to be evaluated, because they not only detect objects, but can also output and evaluate the absolute distance between the Sonar proximity switch and the object. Changing environmental conditions (e.g. temperature variations) are compensated during evaluation of the measurement. SIMATIC PXO optical proximity switches The photoelectric proximity switches react to changes in the received quantity of light. The light beam emitted from the emitter diode is interrupted or reflected by the object to be detected. Depending on the type of BERO, the interruption or reflection of the light beam is evaluated. SIMATIC PXI inductive proximity switches Inductive proximity switches are the low-cost solution for non-contact detection of metal objects. Inductive proximity switches are extremely reliable with a very high repeat accuracy and long service life thanks to nowear operation as well as their insensitivity to temperature, noise, light and water. SIMATIC PXC capacitive proximity switches Capacitive proximity switches are also non-contact sensors for measuring conducting and non-conducting materials in solid, powder or liquid state.

Intelligent proximity switches Easy to insert, simply more productive
Sensors and PLCs are growing together Sensors are becoming more intelligent and versatile. Thus setting and evaluation possibilities are increasing. Thanks to intelligent linking to the PLC, IQ-Link can now be used to implement significantly more flexibility and reliability of the sensors. The uniform exchange of data presents a great number of advantages - for plant construction as well as for its operation. Thanks to the integrated availability of parameters, for example, a setting made on a sensor can be transferred to other sensors as often as required. Central data management ensures that the sensors continue to work with the correct setting values without new parameterizing even after replacement. Furthermore, IQ-Link permits channel-specific system diagnostics. In addition to failures in wiring sensor-specific errors will be detected. Thanks to TIA all these augmented functions are available in the usual system environment without additional configuring. TIA provides this already system integrated.
New communication standard: IO-Link Well-known manufacturers of sensor and automation technologies partnered up under the roof of the PROFIBUS user organization (PNO) to develop an integrated communication standard for sensors and actuators. After completion of the specification at the beginning of 2008 together with the integration into the fieldbus level first IO-Link products will come into the market. Retaining the low-priced point-to-point wiring the goal was to create potential for further cost reductions for the user on commissioning and maintenance costs as well as plant availability. The proven IQ-Sense technology from Siemens was incorporated into the IO-Link specification. Siemens has played and will play a leading role in the creation of the new standard which additionally has been turned in as an IEC standard.

SIMATIC PXS sonar proximity switches Functionality and highlights
Function The sonar proximity switches only operate through the medium of air and can detect any objects that reflect ultrasound. They emit ultrasonic pulses cyclically. When an object reflects these pulses, the resulting echo is received and converted into an electrical signal. The incoming echo is detected in accordance with its intensity which, in turn, is dependent on the distance between the object and the sonar proximity switch. Sonar proximity switches operate according to the echo propagation principle, i.e. the time difference between the emitted pulse and the echo pulse is evaluated. The construction of the sensor causes the ultrasonic beam to be emitted in the shape of a cone. Temperature compensation The proximity switches of compact ranges M30 K2, M30 K3 and M18 are fitted with temperature sensors and a compensation circuit that equalizes changes in operating distances caused by temperature changes.
Highlights ■ Millimeter-accurate measurement ■ Color and material-independent, even transparent objects ■ Individual parameter setting ■ Small, compact housing ■ Very high degree of repeat accuracy ■ UL/CSA approvals ■ Sensors available for Ex Zone 2/22 ■ Insensitive to temperature, noise, light and water
Synchronization In compact ranges M30 K2, M30 K3 and M18, several devices can be synchronized with each other by simply interconnecting the synchronization outputs of the devices. Up to 10 devices can be synchronized (or 6 devices in the case of compact range 0). This allows the sensors to be mounted extremely close to each other in many cases without causing mutual interference. Programming with SONPROG · Programming the devices of the compact ranges M18, M30 K2 and M30 K3 · Possible settings include: · Operating range beginning and end · Analog range beginning and end · Switching hysteresis · Mean value generation · Multiplex mode · NO/NC contact switchover Sensors for Ex Zone 2/22 The PXS800 sonar proximity switches are approved according to EU Guideline 94/9/EG (ATEX) Appendix VIII.

SIMATIC PXO opto proximity switches Fast and accurate sensing with light and laser
The various versions of the SIMATIC PXO opto proximity switches are predominantly used in the following applications: · In conveyor systems · In packaging machines · In mechanical engineering applications · In paper, textile and plastics processing · In printing machines · For access control. These photoelectric sensors detect all objects regardless of their composition, whether metal, wood or plastic. Special versions of the K20 form in miniature enclosure and the C40 are available for detecting transparent objects. Special devices such as the color sensor or color mark sensor can be used to detect differences in color or contrast. An analog laser and also the Fibre-optic sensor support extremely precise distance measurements and position monitoring. Application of a laser distance sensor for precise distance sensing of conveyers would be appropriate. The devices can be mounted in any position. They should be installed in such a manner as to prevent dirt deposits as far as possible.

SIMATIC PXO opto proximity switches Functionality and highlight
Diffuse sensor (energetic sensor) The light from the emitter falls on an object and is reflected in a diffuse pattern. Part of this reflected light reaches the receiver located in the same device. If the intensity of the received light is sufficient, the output is switched. The sensing range depends on the size and color of the object involved as well as its surface texture. The sensing range can be varied within a wide range by means of the built-in potentiometer. The energetic sensor can therefore also be used to detect different colors.
Highlights ■ Extremely precise and quick-acting with pin-point locating ability ■ High performance even across large distances ■ Small, compact housing ■ Reliable measurement even in the smallest spaces with Mini-Sensor (K20/K21) ■ Degree of protection up to IP68
Diffuse sensor with background suppression Diffuse sensors with background suppression can detect objects up to a specific sensing range. All objects beyond this range are suppressed. The focus level can be adjusted. The background is suppressed due to the geometric constellation between the emitter and the receiver.
■ Adjustable ranges
Retroreflective sensors The light from the emitter diode is focused through a lens and directed via a polarization filter to a reflector (principle of a 3way mirror). Part of the reflected light passes through another polarization filter and reaches the receiver. The filters are selected and aligned in such a way that only the light reflected from the reflector reaches the receiver and not the light reflected from other objects within the beam range.
■ Sensing or distance measurement on large distances with laser distance sensors
Thru-beam sensors Thru-beam sensors comprise an emitter and a receiver. The emitter is aligned in such a way that the greatest possible amount of pulsed light from the emitter diode reaches the receiver. The receiver evaluates the incoming light to clearly separate it from the ambient light and other light sources. Sensors for Ex Zone 2/22 The K80 ATEX optical proximity switches are approved according to EU Guideline 94/9/EG (ATEX) Appendix VIII The approval is for:
· Gas EX II 3G EEx nA II T6 X and · Dust EX II 3D IP65 T 80 °C X The functionality of the optical proximity switches with ATEX approval is identical to that of the standard proximity switches.
■ Simple commissioning (Teach-In) ■ UL/CSA approvals ■ Version for use in Ex zone 2/22 (K80 form) ■ Precise sensing of smallest objects with fiber-optic sensors or fork sensors

SIMATIC PXI inductive proximity switches Functionality and highlights
Function A high-frequency alternating field is generated in the proximity switch and emerges at the "sensing face". The physical size of this alternating field determines the "range" of the device. When a material that is a good conductor of electricity and/or magnetism comes into close proximity with the sensing surface, the field is damped. Both states (field damped or undamped) are evaluated in the proximity switch and result in a change in the output state of the switch. Built-in protection: · Spurious switch-on pulse · Short circuit and overload (DC) · Swapped connectors · Wire-break (connection L- or L+), · Overvoltage peaks · Radio interference · Spurious signal suppression The inductive proximity switches are classified in accordance with their applications or their technical characteristics: · for standard duty · for PLCs (2-wire) · for extra electrical duty · for extreme environmental conditions (IP69 K) · with greater operating distance · without a reduction factor · pressure-resistant up to 500 bar (7250 psi) · with analog output · for use in Ex zone 2/22
Highlights ■ Extremely compact and rugged ■ High degree of protection (IP67/IP68/IP69K) ■ Correction factor 1 ■ High sensing ranges ■ Fast switching frequencies ■ Flexible mounting ■ Especially suitable for small spaces ■ UL/CSA approvals ■ Versions for use in Ex zone 2/22

SIMATIC PXC capacitive proximity switches Application examples
SIMATIC PXC capacitive proximity switches detect any material in solid, powder or liquid state, e.g. glass, ceramics, plastics, wood, oil, water, cardboard and paper. Objects can also be detected through certain non-metallic materials. This multi-talented sensor can be applied virtually everywhere: in metalworking and bottling plants, in automation control and for counting all kinds of consumer goods. The capacitive proximity switches operate without contact and wear and thus have a very long service life. Typical applications for capacitive proximity switches are: · Level control in plastic or glass containers · Level signaling in transparent packaging · Winding wire breakage signaling · Tape breakage signaling · Item counting of any kind
Detection of milk in cartons
Level control for bulk material in vessel

SIMATIC PXC capacitive proximity switches Functionality and highlights
Function The sensing face of a capacitive sensor is formed by two concentrically arranged metal electrodes that are equivalent to the electrodes of an unwound capacitor. The electrode surfaces A and B are connected into the feedback branch of a high-frequency oscillator that is tuned such that it does not oscillate when the surface is free. When an object approaches the active face of the sensor, it enters the electric field in front of the electrode surfaces and causes a change in the coupling capacitance. The oscillator starts to oscillate; the amplitude is recorded by an evaluation circuit and converted into a switching command.
Highlights ■ Detection of all materials (e.g. plastics,wood, paper) ■ Measurement of liquid through plastic tubes or glass pipes ■ Measurement of aggressive chemicals ■ Adjustment of the operating distance on the object
Switching frequency
The build-up characteristics specific to other pulse/interval conditions may result in higher switching frequencies than those specified. Operating distance The stated values are applicable to a target of metal which is grounded and whose area corresponds to the sensing face of the proximity switch. The real operating distance sr for nonconductive targets is dependent on the relative dielectric constant er and the characteristic value (see characteristic curve).
Built-in protection: · Spurious signal suppression · Short-circuit and overload protection · Polarity reversal protection for connections · Inductive interference protection
Dielectric constants of various materials: · Glass 5 · Paper 2.3 · Vacuum, air 1 · Water 80

SIRIUS detection devices are paying attention!
Siemens also offers a wide range of mechanical sensors in addition to the non-contact proximity switches of the SIMATIC Sensors range. The new SIRIUS spectrum of detection devices ranges from position switches in different versions, through hinge switches to magnetically operated switches. Standard position switches: reliable and conforming to standards With a wide range of new features, this new generation of position switches is successfully used in virtually all applications: · Detection of hazardous movements of machine parts · Monitoring of protection equipment with rotary joints, such as swiveling doors, access flaps, lids, etc. · Monitoring of lateral-motion protection equipment, such as sliding doors, guards, etc. The dimensions, fixing points and characteristics of our position switches largely comply with EN 50041 or EN 50047. Whether in plastic or metal enclosures: we have the right switch for your specific requirements. Reduced installation time and increased flexibility can be archieved through modular construction of individual components and simple connection for plastic housing.

Short-stroke switches: accurate and compatible Exact switching is required when monitoring doors and access flaps. No problem for our position switches with short-stroke switching element. Position switch with separate actuator: proven and safe With their largely standardized housings and operating mechanism types, our standard position switches have been tried and tested in the monitoring of protection doors. An alternative is to use a position switch with a separate actuator. It has multiple mechanical coding to prevent easy manipulation and thus overriding of safety equipment. The switching unit is fixed to the door frame and the actuator to the protection door. In the safe state, i.e. with the protection door closed, the operating mechanism is seated snugly in the operating head of the switch and actuates the contacts, which open with positive action when the door is opened.

SIRIUS detection devices The right detection device for every application
Position switch with tumbler: clever and reliable Position switches with a separate actuator and an additional electromagnetic tumbler are used if an interlock is required on a protection door, e.g. to secure the operating area of a robot. They keep the protection door interlocked until the operating area can be entered without danger. In other words: until the machine has come to a complete standstill or a non-critical speed has been reached. An electrical signal, e.g. from a safe zero-speed monitor, then actuates the interlock solenoid and releases the protection door. Position switches have a greater degree of security through locking pressure of up to 2600 N in the metal version and up to 1300 N in the plastic version even in harsh working environments.
Magnetically operated switches: Compact and secure against manipulation Magnetically operated switches are contactless and are especially suitable for monitoring protection doors. The reed contacts in the switching element are actuated by a coded switching magnet and are thus particularly tamper-proof. The members of our 3SE6 family of magnetically operated switches, in conjunction with ASIsafe 3RK modules and 3TK28 electronic safety modules, are approved up to Cat. 4 in conformity with EN 954-1.
Hinge switches: Easy to mount Our range of hinge switches completes the spectrum of position switches for monitoring swiveling doors and flaps. These mechanical switches provide maximum protection against tampering and manipulation thanks to the snug connection between the switch and the protection door hinge.
