SMR and SPR Series magnetic non-contact safety
switches with universal 22 mm (0.87") fitting have been
designed to enable the conformance to EN60947-5-3
and be used as directed by ISO12100, ISO14121
and EN60204-1. They have magnetic sensing which
provides a wide sensing distance and provides a high
tolerance to misalignment after sensing. They can
operate from 4 directions even in extreme environments
of temperature and moisture. They have volt free
high power switching capability and can be used
independently to switch low risk applications or connect
to a safety relay to provide higher safety levels. When
used in combination with most dual channel safety
monitoring relays they can be used to provide up to
PLe/Category 4 to ISO13849-1.
SMR and SPR Series magnetic non-contact safety
switches are designed to interlock hinged, sliding or
removable guard doors. SMR Series stainless steel
safety switches have been designed for applications in
the food processing, pharmaceutical, packaging and
petro chemical industries. SPR Series switches have
been developed for applications in general factory
automation, packaging and some food processing
industries.
They are specifically advantageous when: • Poor guard alignment exists and a wide tolerance to
misalignment is required • High levels of hygiene is a requirement, e.g. high
pressure chemical or water hosing in the food industry environment • Environments where high switching capacity is a
requirement
