Limit Slot Photoelectric Sensor

The slot-type photoelectric sensor is a photoelectric switch. A light transmitter and a receiver are mounted on both sides of a slot face to face to form a slot-shaped photoelectric sensor. But when the detected object passes through the slot, the light is blocked, the photoelectric switch will act, and output a switch control signal to cut off or turn on the load current, thereby completing a control action. The detection distance of the slot switch is generally only a few centimeters due to the limitation of the overall structure.
