Photocell for gate motor

A photocell, also known as a photoelectric sensor or photoelectric beam sensor, is a device commonly used in gate motors for safety purposes. It detects the presence of objects or obstructions in the path of a closing gate and sends a signal to the motor to prevent it from closing or to reverse its motion.

Here's how a photocell system typically works in a gate motor:

1.Installation: Photocells are installed on either side of the gate, facing each other. They consist of two units: a transmitter and a receiver. The transmitter emits an infrared beam, and the receiver detects the beam.

2.Beam Interruption: When the gate is closing, the infrared beam between the transmitter and receiver should be uninterrupted. If an object or obstruction, such as a person or a vehicle, breaks the beam, the receiver detects the interruption.

3. Signal Transmission: When the receiver detects a beam interruption, it sends a signal to the gate motor controller or control board.

4.Motor Response: Upon receiving the signal from the photocell system, the gate motor controller takes appropriate action. This can include stopping the gate's motion, reversing its direction, or preventing it from closing altogether.

5.The purpose of using photocells in gate motors is to enhance safety by preventing the gate from closing on objects or people in its path. It's a crucial feature to avoid accidents or injuries caused by gate closure. Photocells are commonly found in both residential and commercial gate motor systems.

6.When purchasing a gate motor, make sure it supports the use of photocells and consult the manufacturer's instructions for proper installation and integration with the motor control system.
