Product Name : PJ-1010 slotted photo interrupter sensor
A light emitter and a receiver are placed face to face on both sides of a slot to form a groove.A light-emitting device can emit infrared or visible light, and a light receiver can receive light without interference.However, when the detected object passes through the slot and the light is blocked, the photoelectric switch will act and output a switch control signal, cutting off or switching on the load current, thus completing a control action.The detection distance of groove switch is only a few centimeters due to the restriction of the whole structure.
