CM3-Ex

CM3-Ex Explosion Proof Stainless Steel Safety Interlock

IDEM’s CM3-Ex Explosion Proof Non Contact Switches are manufactured in Stainless Steel 316 are designed to interlock hinged, sliding or removal guard doors or hatches. All electrical switching contacts are fully encapsulated within the switch and have a Stainless Steel 316 back plate to prevent tampering with the internal components.The CM-Ex Range is designed with highly reliable power reed switching elements, contacts de-rated and protected by internal fuses with high tolerance to guard misalignment.Manufactured with a magnetic sensing system which provides a wide sensing distance and provides a high tolerance to misalignment after sensing. The CM-Ex Range can be fitted behind stainless steel fittings and can operate in extreme environments of temperature and moisture.The range is available pre-wired with 5m or 10m cable and a choice of circuits (see catalogue pages for circuits).
