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. High-brightness LEDs on both the emitter and receiver provide clear visibility from side, front, and long distances. The sensor incorporates essential functions such as self-diagnosis, mutual interference prevention, and external diagnosis, enhancing operational reliability. It is built with a robust IP65 protection structure, making it suitable for demanding industrial environments.
