Product Overview
The D-44 BW Series Area Sensor is a 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 or 40mm, and sensing heights from 120mm to 940mm. The 20mm optical axis pitch (BW20-) minimizes unsensing areas, while high-brightness LEDs on both the emitter and receiver ensure easy recognition from side, front, and long distances. This sensor includes essential functions such as self-diagnosis, mutual interference prevention, and external diagnosis, and boasts an IP65 protection structure for robust operation in industrial environments. It is suitable for detecting opaque materials of specified minimum diameters.
