Product Description
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 minimizes unsensing areas, making it ideal for precise detection. Both emitter and receiver units are equipped with high-brightness LEDs for easy recognition from various angles and distances. This sensor includes essential functions such as self-diagnosis, mutual interference prevention, and external diagnosis, ensuring reliable operation in industrial environments. Its robust IP65 protection structure (IEC standard) makes it suitable for demanding applications.
