The LiftMaster 50-15514 IR Emitter is a genuine OEM infrared transmitter used in select LiftMaster photoelectric safety sensor assemblies. It projects a focused IR beam that, when aligned with its matching receiver, enables non-contact obstruction detection for compatible door and gate operator systems. This replacement emitter is intended to restore proper beam operation on LiftMaster setups that specifically call out part number 50-15514 in their service manuals or parts diagrams, commonly found on garage door, commercial door, and gate operator applications.
Correct installation requires proper alignment to the paired receiver, clean optics, and secure low-voltage wiring per the operator’s manual. For safety and compliance, installation and testing should be performed by a qualified technician, and the system’s entrapment protection must be verified in accordance with the operator’s service procedures and applicable standards such as UL 325. This is not a universal component; confirm compatibility with your LiftMaster model before ordering by referencing official documentation for part number 50-15514 IR Emitter.
