A safety device that includes a Receive and modulated infrared Transmitter, the self-aligning cell is called a self-aligning Photocell. The Receive is broken by a break in the path of the electrical contact. The function of photocell sensors
1. Use microprocessor control (CPU) to create a digital circuit.
2. Professional waterproof design with rubber seal
3. A single beam sensor/single beam detect is used to control automatic slide doors, coil doors, garage door windows, and so on.
4. It consists of a transmitter, a receiver, as well as an integrated amplifier that can produce an infrared light beam
