Safety proximity sensors

With their encapsulated and contactless design, safety proximity sensors are insensitive to contamination and humidity. They operate free from wear and also have a long life expectancy, even with frequent operating cycles. They are also used wherever it is difficult to precisely guide the moveable protective device. All devices feature a high-strength plastic housing. Furthermore, the devices with RFID transponder provide maximum protection against tampering.

Advantages for you

  • Wear-free operation and long life expectancy: Safety proximity sensors operate free from wear and also have a long life expectancy, even with frequent operating cycles
  • Optimum protection against manipulation: The RFID‑coded actuators of the RD800 safety transponder offer optimum protection against manipulation
  • Performance Level e: Even with just one device, the RD800 safety transponders achieve performance level PL e in accordance with EN ISO 13849-1.

Monitoring of doors and flaps
Protection against manipulation integrated in the sensor

  • For use in dusty, dirty and damp environments
  • The RFID‑coded actuators offer optimum protection against manipulation. Extra installation measures are therefore no longer necessary
  • Long life expectancy, even with frequent operating cycles, thanks to wear-free operation
  • For applications with actuators with low or high coding level in accordance with EN ISO 14119
  • Simple integration via OSSD safety outputs. Performance level e in accordance with EN ISO 13849-1 is already achieved with just one device
  • Wide operating area for flexibility when installing and for applications with large tolerances.
  • Degrees of protection IP 67 / IP 69K for demanding environmental conditions
  • Connection via cable or connector

Which standards are important for safety switches?

The guidelines for selecting interlock devices in combination with guards are described in the international standard ISO 14119. Here, the term "interlock devices" also refers to contactless safety proximity sensors. They are mounted on, for example, safety doors or flaps and trigger safe shutdown of a machine or system when the protective device is opened. The complete designation of ISO 14119 is: Safety of machinery – Interlocking devices associated with guards – Principles for design and selection. Here, the standard defines four different types of interlock devices and lists their advantages and disadvantages. It also addresses measures for minimizing the bypassing of interlock devices.

Further information on the safeguarding of physical safety guards can be found in the "Specialist knowledge" section.
