Functions and Operating Principle

The sensor operates on the polarized reflection principle, using polarized light and a special filter to accurately detect objects even on reflective surfaces.
It distinguishes objects from shiny backgrounds (e.g., metal surfaces, glass, or mirror materials).
360° visible LED indicators allow easy monitoring from any angle, while a single-turn adjustment knob ensures quick and precise setup.

Usage and Application

For home users or craftsmen: Suitable for object detection in workshops or custom automation projects.
For engineers / automation specialists: Used in manufacturing, sorting, packaging, conveyor, and transport systems, as well as robotics applications requiring precise object position detection.
For electricians / technicians: Easy to install due to the compact square housing, while clear LED indicators allow quick status and fault identification.

Pros

Adjustable detection distance

Durable ABS housing with IP67 protection

Fast response time

Visible red light spot – easy alignment

Works with shiny or semi-transparent objects

Cons

ABS housing is less robust than metal models

Requires proper alignment and reflection conditions
