Electronic Spices Adjustable Diffuse Reflection photoelectric Switch Sensor Optical Three Lines Normally Open Proximity Switch Electronic Components Electronic Hobby Kit

DC 3 Wire proximity switch module is a reflection-type photoelectric sensor. It integrates transmitting and receiving infrared beams function. This infrared proximity switch works by sending out beams of invisible infrared light. This proximity sensor contains a photodetector that detects any reflections of this light.If a proximity sensor detects reflection then it allows infrared proximity switches to determine whether there Is an object nearby. If we arrange cross beams then it consists of a receiver located in the line of sight of the transmitter. In this mode, an object is detected when the light beam is blocked to reach the receiver from the transmitter
