LiftMaster CPSUN4G Monitored Through-Beam Photo Eyes

Commercial Monitored Photo Eyes for LiftMaster Gate Operators

The LiftMaster CPSUN4G Monitored Through-Beam Photo Eyes are commercial-grade, UL 325-compliant entrapment protection sensors engineered for precise obstacle detection in gate and door automation systems. Designed for long-range performance up to 45 feet, the CPSUN4G uses a monitored infrared beam between an emitter and receiver to halt and reverse the gate upon obstruction detection. Built with NEMA 4 weather-resistant housing, LED status indicators, and wireless network capability, it offers dependable performance for both wired and solar-powered installations.
