The LiftMaster LMRRUL monitored retro reflective photo eye gives your gate a dependable external entrapment protection device built to meet UL 325 safety standards. It protects people, vehicles, and equipment by stopping or reversing the gate when the beam path is blocked. This photo eye fits applications where you need reliable detection at the entrance and you want fast alignment and long-range performance.

LMRRUL delivers sensing distance up to 50 feet and uses a retro reflective design that requires power on only one side of the installation. This cuts wiring time and keeps the install clean. You also get an increased beam angle for easier alignment, plus an alignment strength indicator that helps your installer confirm optimal beam position.

For tough weather and demanding sites, the sensor includes a built-in heater for dependable performance in most environments and a NEMA 4X rating for strong protection against rain, dust, and harsh conditions. The kit includes a steel sensor hood, durable polyethylene reflector hood, a 10-foot wire, brackets, and mounting hardware so you can complete the install without chasing extra parts.
