Garage Door Sensor, Wireless Single Infrared Gate Beam Photocell Sensor, 4 Set

What is this?
The Photoelectric Eye Beam Sensor is a photoelectric sensor that uses infrared light to detect the presence of an object. It creates a safety barrier, detecting any movement between the transmitter and receiver. Once the infrared beam is blocked, the door is perfectly controlled to stop or reverse automatically.

How to use it?
The best installation height should be greater than 20CM, and the installation distance should not be less than 2 meters. When installing, the infrared protection device should be placed vertically and on the same horizontal line. When installing, install the receiving part first, then install the transmitting part. When they are in the same straight line, the OFF light in the receiver is off, then fix it, connect the wires, and the installation is complete.

What should  I notice?
Due to the high transmission power of this product, there will be no response when the distance between the transmitter and receiver is too close. In this case, they should be separated by at least 1M and tried again.
