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.

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.
