    Photoelectric sensor operating on the polarized reflection principle.
    It features high detection accuracy, resistance to environmental interference, and the ability to reliably detect transparent, semi-transparent, and reflective objects.

    With adjustable detection distance and integrated NPN+PNP output (NO/NC mode switchable via potentiometer), this model is suitable for both general automation systems and specialized production lines.

    Made of durable PC/ABS plastic with IP67 protection against dust and moisture, it ensures long-term operation even in harsh industrial environments.
