Durable through beam sensor Autonics BW20-28P with acrylic sensing part and infrared led light source
Product Overview
The D-44 BW Series Area Sensor is a high-performance through-beam type photoelectric sensor designed for long-distance detection up to 7 meters. It offers a wide range of configurations with 22 product types, featuring optical axis pitches of 20mm and 40mm, and sensing heights from 120mm to 940mm. The 20mm optical axis pitch (BW20-) minimizes unsensing areas, while high-brightness LEDs ensure easy recognition from side, front, and long distances. This sensor includes essential functions such as self-diagnosis, mutual interference prevention, and external diagnosis, all housed within a robust IP65 protected structure. Ideal for industrial automation and detection applications requiring reliable and precise sensing.
