Simply set up the transmitter on one side of a doorway, and the receiver on the other, and when the beam is interrupted, the relay will be triggered. You can hook up almost anything, such as a chime to alert you. This module is great for stores. Never be caught off guard when a customer enters softly. Transmitter and receiver both use 12 volts DC.

- Power supply for transmitter = 12Vdc./20mA.max.
- Power supply for receiver = 12Vdc. has signal = 15 mA. and has no signal = 50mA.
- The OUT-point output is active HIGH when the RX has signal and is active LOW when the TX has no signal.
- Delay timer : adjustable between 1 to 10 second.
- The operation can be reflective or barrier.
- Detecting distance for reflective approximate 3 ft.
- Detecting distance for barrier approximate 10-80 ft.
- PCB dimensions : 2.35x2.33 inch. For TX (Transmitter) , 2.17x2.38 inch. For RX (Receiver)
- Recommended Housing : FB04 for both TX and RX
