Liftmaster Monitored Thru-Beam PE w/ heater

The Liftmaster Monitored Thru-Beam Photo Eye with heater (SKU LMTBUL) is a UL Recognized entrapment-protection sensor designed to work with Liftmaster's 2018 UL 325 gate operators and their integrated diagnostics. As a thru-beam system, it provides a long-range sensing distance of up to 90 ft., making it a versatile solution for safeguarding gate openings against entrapment.

Engineered for harsh applications, this photo eye carries a NEMA 4X rating for superior weather resistance and ships with durable hoods to shield it from the elements. A built-in heater supports dependable performance in most environments, while a wider beam angle and a versatile gimble bracket simplify alignment and fine adjustment. Multi-view LED status lights and an alignment strength indicator make installation and troubleshooting straightforward, with solid blue indicating optimal alignment, blinking blue indicating near alignment, and solid red indicating a misaligned or obstructed beam.

For dual-gate applications, wireless network capability eliminates the need to wire between operators. The LMTBUL is built with quality-grade materials including a stainless-steel sensor hood, a durable polycarbonate reflector hood, and powder-coated galvanized mounting brackets. Note that the LMTBUL emitter is not interchangeable with the LMRRUL emitter.
