The IRB-RET is a monitored, weather-proof retroreflective photo eye solution providing entrapment protection for automatic gates and doors. Retro-reflective configuration eliminates the need for a separate transmitter and the associated wiring across a roadway to reduce installation costs. The IRB-RET is UL 325-2016 compliant and housed in a rugged NEMA 4X enclosure suitable for indoor and outdoor use.

The universal design of the IRB-RET allows it to be used with a wide variety of monitored operators. Additionally, it is compatible with most non-monitored legacy products.

The IRB-RET has 5 monitoring interfaces:

  • Normally closed
  • Two-wire pulsed (2 freq)
  • Two-wire pulsed (3 freq)
  • Four-wire pulsed
  • 10k resistor termination

See the spec sheet for complete interface details.

The long range and retro reflective features provide a flexible solution to all external entrapment protection needs.
