The CMR and CPR Series magnetic non-contact safetyswitches with compact slim fitting housing have beendesigned to enable the conformance to EN60947-5-3and be used as directed by ISO12100, ISO14121and EN60204-1. They have magnetic sensing whichprovides a wide sensing distance and provides a high tolerance to misalignment after sensing. Theycan operate from 4 directions even in extremeenvironments of temperature and moisture. They havevolt free high power switching capability and can beused independently to switch low risk applicationsor connect to a safety relay to provide higher safetylevels. When used in combination with most dualchannel safety monitoring relays they can be used toprovide up to PLe/Category 4 to ISO13849-1.

CMR and CPR Series magnetic non-contact safetyswitches are designed to interlock hinged, sliding orremovable guard doors. CMR Series stainless steelsafety switches have been designed for applications inthe food processing, pharmaceutical, packaging andpetrochemical industries. CPR Series switches havebeen developed for applications in general factoryautomation, packaging and some food processingindustries.

They are specifically advantageous when:
     Poor guard alignment exists and a wide toleranceto misalignment is required
     High levels of hygiene is a requirement, e.g. highpressure chemical or water hosing in the food industry environment
     Environments where high switching capacity is arequirement
