Functions and Operating Principle

The sensor operates on the through-beam principle – the transmitter and receiver are mounted facing each other. When an object passes between them and interrupts the beam, the sensor is activated.
It allows for precise object detection and is suitable for high-speed production lines.
Adjustable sensing distance and easy NO/NC switching make it adaptable to different automation systems.

Application

For home users or hobbyists: Suitable for object detection in workshops or DIY automation projects.
For engineers / automation specialists: Ideal for robotics, production lines, conveyors, counting, and positioning systems.
For electricians / technicians: Compact housing ensures easy installation; clear LED indicators help quickly identify operating status and possible faults.

Pros

Fast response

IP67 sealing – dust and moisture resistant

Adjustable detection distance

Clear 360° LED indication

Cons

Requires precise alignment of transmitter and receiver

May be less effective with strong reflections or very small objects
