DescriptionSMR and SPR Series magnetic non-contact safetyswitches with universal 22 mm (0.87") fitting 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 hightolerance to misalignment after sensing. They canoperate from 4 directions even in extreme environmentsof temperature and moisture. They have volt freehigh power switching capability and can be usedindependently to switch low risk applications or connectto a safety relay to provide higher safety levels. Whenused in combination with most dual channel safetymonitoring relays they can be used to provide up toPLe/Category 4 to ISO13849-1.
