Universal Retroreflective Photoeye IRB-RET

UL 325-2016 NEMA 4X

The IRB-RET is a monitored, weather-proof retroreflective photoeye solution providing entrapment protection for automatic gates and doors. Retroreflective 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 resistive termination

See the spec sheet for complete interface details.

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

Benefits include:

• Selectable monitoring interface for easy set-up and installation
• Compatible with many operators
• Long operating range
• Robust design minimizes fogging and false triggering to provide easy alignment
• Mounting bracket and reflector provided
