IR Light Barrier 4m

The DFRobot IR light barrier consists of a transmitter and a receiver. The transmitter sends an invisible infrared beam to the receiver; when the beam is interrupted by a non-transparent object, the receiver changes its output signal. The range is up to 4 m and the response time 0.5 ms. Both parts are small, operate at 5 V and have cables with Dupont plugs.

Features:

• Through-beam light barrier with separate transmitter and receiver
• Range up to 4 m
