This is a set of transmitter and receiver in one photoelectric sensor. The detection distance can be adjusted upon request. The sensor features a detection distance and addresses visible light interference; it is cheap, easy to assemble, and easy to use. Features of robot obstacle avoidance and assembly line piece counting make it widely applicable in many situations.
