Overview
For commercial gate and door safety where reliable monitoring matters, the LiftMaster CPS-RPEN4 Photo‑Eye N4 1‑Sided Monitored Sensor delivers dependable obstruction detection and simplified installation. Designed for LiftMaster gate operators and commercial door systems, this monitored retro‑reflective sensor uses a polarized beam to minimize false alarms from reflective surfaces and provides consistent performance up to 50 ft. The NEMA 4X enclosure protects electronics from weather and contaminants, extending service life in outdoor security and surveillance environments.
Because the CPS‑RPEN4 requires power on only one side, integration is faster and more cost‑effective—reducing installer time by roughly 30%. It is UL 325 compliant and suitable as a primary or ancillary entrapment device, helping you meet safety regulations while maintaining reliable monitoring. Adjustable alignment and an armored power cable make setup and maintenance straightforward for busy facilities managers and integrators.
Ideal for commercial doors, loading docks, and perimeter gate applications where safety and uptime are priorities. Add the LiftMaster CPS‑RPEN4 to your security and access-control solution to improve protection and reduce installation complexity—order now or contact us for volume quotes.
