CMR: Magnetic Non Contact Safety Interlock Switch

CMR: Magnetic Non Contact Safety Interlock Switch


IDEM’s magnetic, non-contact safety interlocks are designed to conform to IEC 60947-5-3 and be used as directed by ISO12100, ISO14121 and ISO14119. They feature magnet and reed technology, providing a high tolerance to misalignment and extreme temperatures.

The mechanical operations means the contacts are volt free with a high power switching capability of 1A or 2A ac/dc. They are suitable for hinged, sliding or removable guard applications and can connect to most safety relays to provide a higher level of functional safety.


  • Housing/Fixing: Slim 20mm body
  • Material: Mirror Polish (Ra4), 316 stainless steel ideal for exposure to chemical cleaning agents
  • Contacts: Up to 2 N/C safety outputs and 1 N/O auxiliary output.
  • Sensing Distance: Wide 12mm operation
  • Ingress Protection: IP67 and IP69K
  • Operating Temperature: -25C to 105C
  • Connection: Pre-Wired or M12 8-pole Quick Connect

Special Features:

  • Suitable for Splash Zones in accordance with EHEDG guidelines
