Key Features & Strengths:

Compact and Robust Design: The sensor features a compact, rectangular plastic housing that allows for easy integration into machinery with limited space while maintaining durability in industrial environments.

Polarization Filter (Key Feature): This model is equipped with a polarization filter. This is a critical feature that allows the sensor to reliably detect shiny, reflective objects (like metallized packaging or polished surfaces) without false triggers. The filter ensures the sensor only recognizes light returned from its specific corner-cube reflector.

Retro-Reflective Sensing: Offers a longer sensing range than diffuse sensors while keeping the wiring simple, as only the sensor itself needs to be wired.

Visible Red Light Beam: Uses a visible red light beam, which simplifies the alignment process with the reflector during installation and setup.

Fixed Cable Connection: The model suffix suggests a fixed cable connection for a secure and reliable interface to the control system.

LED Status Indicator: Features an LED for clear visual confirmation of the switching status, aiding in setup and diagnostics.
