For any machine requiring a fixed guard-door or cover, the YSM series ensures reliable state monitoring (door open or closed). A magnetically coded system (type 4 according to ISO 14119) makes the YSM series immune to mutual interference and highly resistant to tampering. It is also possible to mount the actuator behind a stainless steel plate, which further reduces accessibility.

The YSM series is part of a range of non-contact safety sensors used to monitor guard-doors, hoods or covers. Thanks to non-contact switching and coded communication, the service life of these compact sensors is very long. Housings are ECOLAB-approved and rated to IP6K9K, making them suitable for washdown applications.

Safety level is category 4 according to ISO 13849-1.
