LiftMaster LMRRUL Monitored Retro Reflective Photo Eye, Long Range Sensing Distance up to 50' Meets UL 325 Safety Standards

Built for dependable perimeter safety and vehicle monitoring, the LiftMaster Monitored Retro Reflective Photo Eye (LMRRUL) brings long-range sensing and code-compliant protection to gate operators. This monitored photo eye delivers reliable detection up to 50 ft, helping integrators and facility managers prevent entrapment and reduce nuisance activations across commercial and residential gates. Because it requires power on only one side, the LMRRUL cuts installation time and material costs on new installs and retrofits.

Engineered for real-world conditions, the sensor includes a built-in heater, an alignment strength indicator for quick setup, and rugged housings (steel sensor hood and polyethylene reflector hood) rated NEMA 4X. Meeting UL 325 safety standards, the LiftMaster LMRRUL integrates seamlessly with LiftMaster gate operators to provide consistent monitoring and enhanced security. Ideal for security, surveillance and access control projects where reliability and code compliance matter.
