Laser through beam Switch consist of transmitter which is a laser diode which operates at 5VDC and a receiver module with NPN type output. It can be used to detect intruders/obstruction for any type of alarm system. It can also be used as a fencing.
- Operating voltage: Transmitter DC3.3-5V, Receiver: DC4.5-17V
- Operating Current: Transmitter: 40mA, Receiver: 30mA
- Detection distance 0-30Meters
- Output signal: NPN Output can directly drive a small relay without transistor
- Brown: +VDD
- Blue: GND
- Black: Signal
