Infrared Light Barrier 1.5m 12-24V

This infrared light barrier from DFRobot consists of a transmitter and a receiver in small plastic housings. If the beam between the two is interrupted, the NPN output of the receiver switches. The range is up to 1.5 m, the response time below 1 ms. It is supplied with 12 V to 24 V DC. It is suitable for counting, time measurement at robot competitions and detecting passages.

Caution: The light barrier is operated with 12 V to 24 V. To connect it to an Arduino or another board with 5 V or 3.3 V inputs, adapt the signal with an optocoupler or a voltage divider.
