Functional Features
Polarization Filter: The core feature that enables reliable detection of highly reflective objects by breaking the light's polarization. It will not detect a standard reflector without an object present.

Short, Adjustable Range: The sensing range is optimized for close-up applications and can be finely tuned to the specific target and environment.

Simple Setup: Features a potentiometer for easy sensitivity adjustment to compensate for different object surfaces or to ignore background interference.

Compact Size: Small form factor allows for easy integration into machinery with limited space.

Fixed Cable: The integrated 2-meter cable provides a robust connection, eliminating the need for a separate connector.

Typical Applications
Detection of transparent objects: Bottles, glass panes, plastic films.

Detection of shiny/metallic objects: Foil packaging, canned goods, metal parts.

Label detection: Verifying the presence of labels on backing paper.

Door or cover monitoring: Detecting if a reflective safety door is closed.

Object counting on conveyor belts, especially when objects have reflective surfaces.
