    EMX’s IRB-RET is an infrared retro reflective photoeye for automatic gates and garage doors. Retroreflective photoeyes use a reflective surface mounted across from the photoeye to reflect back the signal. The IRB-RET is an external entrapment device type B1, non-contact sensor with a straightforward single wiring set up. With an operating range of up to 60 ft. over a wide range of voltages and a built-in alignment light, installation is straightforward and easy on virtually any installation. The IRB-RET provides compatibility with most operators that accommodate monitored external entrapment devices per UL325.
