Product Overview
The D-44 BW Series Area Sensor is a high-performance through-beam type 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, ensuring comprehensive coverage. Its high-brightness LED emitter and receiver provide excellent visibility from side, front, and long distances, aiding in easy recognition. The sensor is equipped with a self-diagnosis function, mutual interference prevention, and external diagnosis capabilities for reliable operation. It is built to withstand harsh environments with an IP65 protection structure (IEC standard).
