4-Wire Slot Type Photoelectric Switch (5mm, PNP, 10-30V)

The 4-Wire Slot Type Photoelectric Switch is an industrial optical sensor designed for dependable limit sensing, speed measurement, and position detection. Operating from a 10-30V DC power supply, it is well suited for makers, hobbyists, and engineering students working on automation and robotics projects.

Fixed 5mm optical gap

The sensor features a 5mm slot width for direct through-beam optical sensing of passing objects and encoder wheels.

Wide 10-30V DC input

It operates on a 10V to 30V DC supply range, making it compatible with standard industrial power rails and control hardware.

Dual PNP outputs

The 4-wire interface provides both normally open (NO) and normally closed (NC) PNP outputs for flexible logic wiring.

Fast 500Hz switching performance

A response time of less than 1.5ms combined with a 500Hz switching frequency allows for accurate, high-speed detection.
