4-Wire Slot Type Photoelectric Switch

A 4-wire slot-type photoelectric switch with integrated optical transmitter and receiver. The 5mm detection slot can detect objects passing through, including transparent materials, making it ideal for counting, position sensing, and high-speed object detection in industrial and hobby applications.

The module operates on 10–30V DC with PNP output and provides both normally open (NO) and normally closed (NC) connections simultaneously. Built-in short-circuit, overload, and reverse-connection protection ensure reliable operation. An onboard LED indicator shows detection status in real time.
