Specifications subject to change without notice



  • Low cost, PCB form factor
  • For use with either 50/125 OM2/OM3 or 62.6/125 OM1 multimode fiber
  • Controller’s inherently safe, optical radiation is approved for EPL Mb/Gb/Gc/Db/Dc applications
  • For increased safety, the controller is designed to default to the emergency state when: (1) switch is depressed, (2) in case of broken fiber, (3) in case of a fiber being disconnected, or (4) loss of power.


  • Digital logic output
  • Open-Collector output for controlling an external relay
