Application:
The position switches with safety function are suitable for sliding and hinged guards, which need to be closed in order to ensure the required operational safety.

In combination with safety control modules all safety switches with class 1 shown in this chapter achieve Control Category 3 or 4 to ISO 13849-1

Further applications for positions switches class 1 are most varied positioning duties. A comprehensive range of actuating elements is available to meet the requirements of many everyday tasks.

Design and mode of operation:
On the position switches class 1 the guarding device and the positive break NC contact are positively linked.

Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position.
