Autonics BJ3M-PDT-C-P Photoelectric Sensor, Industrial Object Detection Sensor

The Autonics BJ3M-PDT-C-P is a compact, high-performance polarized retroreflective photoelectric sensor designed for reliable industrial object detection. It uses a red LED light source and a built-in polarizing filter to detect opaque objects up to 3 m away. The sensor operates on 12–24 VDC, offers a fast 1 ms response time, and provides a PNP open collector output with selectable Light ON / Dark ON operation.
