LiftMaster 41A4373 Photocell Sensor – American Access-Automation Safety-Beam Technology
LiftMaster 41A4373 is a professional photocell safety sensor designed to improve obstacle detection and operational safety in compatible automatic gate, door or barrier systems. It uses infrared or optical detection technology to monitor the protected opening and provide a safety signal to the automation controller when the beam is interrupted.
Developed with American access-automation safety-beam technology, the LiftMaster 41A4373 is suitable for professional automation projects in the United Arab Emirates. The final safety response—such as stopping, preventing closing or reversing movement—is determined by the connected control board and its programming.

Frequently Asked Questions About LiftMaster 41A4373
What is the LiftMaster 41A4373 used for?
It is used as an optical safety sensor for compatible automatic gate, door or barrier systems. When the protected beam is interrupted, the sensor changes its safety output or BUS status so the control board can react according to its programmed logic.
What is the detection range of the LiftMaster 41A4373?
The exact operating range should be confirmed from the supplied model label or manufacturer documentation before installation, particularly where the product family has multiple variants.
How is the LiftMaster 41A4373 connected?
Connection depends on the exact control board and sensor version. Confirm the accessory supply, safety input and wiring diagram before installation.
Can the LiftMaster 41A4373 be used with sliding and swing gates?
It can be used where the automation controller is electrically and functionally compatible with this sensor. Compatibility should be checked by control-board model rather than by gate type alone.
Is installation support available in the United Arab Emirates?
Yes. Professional compatibility checking, installation, alignment, programming support and safety testing can be arranged for suitable automation systems across the United Arab Emirates.
