IRB-MON

IRB-MON PHOTOEYE OVERVIEW

The IRB-MON is a monitored, weather-proof, thru beam infrared photoeye solution providing entrapment protection for doors, gates and barriers. The IRB-MON Safety Photo Beam is UL325-2018 compliant and housed in a rugged NEMA 4X enclosure suitable for indoor and outdoor use.

This universal UL325 thru beam photoeye can be used with a wide variety of monitored operators. Additionally, the IRB-MON photoeye is compatible with most non-monitored legacy products. Its robust construction minimizes fogging and false triggering to provide easy alignment.
