5V IR Photoelectric Switch (4m)

This IR break-beam photoelectric switch detects objects by sending an invisible infrared beam from an emitter to a receiver. When a non-transparent object passes between the two and breaks the beam, the receiver outputs a signal. It works over distances up to 4 metres with a fast 0.5ms response time.

Powered by 5V DC, this sensor is compatible with Arduino and other microcontrollers for motion detection, speed measurement, timing, and counting applications. Its compact size allows installation in tight spaces.
