Function and Operating Principle
The sensor operates on the polarized retro-reflective principle – the light beam is emitted toward the reflector and the return signal is detected only at a specific polarization angle.
Ensures precise object detection even under strong light or reflective surfaces.
A single-button control allows quick adjustment of detection distance and NO/NC mode switching, providing user-friendly operation.

Application and Use
For home users or hobbyists: Suitable for object detection in workshops or DIY automation projects.
For engineers / automation specialists: Applicable in manufacturing, sorting, packaging, conveyor, and transport systems, as well as robotics applications requiring accurate object position detection.
For electricians / technicians: Easy installation due to compact square housing, with clear LED indicators for quick status and error diagnostics.
