Product Overview
The D-44 BW Series Area Sensor is a high-performance through-beam photoelectric sensor designed for long-distance detection up to 7 meters. It offers a versatile range of models with varying optical axis pitches (20mm or 40mm) and sensing heights (120mm to 940mm), minimizing unsensing areas and ensuring reliable detection of opaque targets as small as 30mm or 50mm. Featuring a high-brightness LED for easy visibility from multiple angles and distances, this sensor incorporates essential functions like self-diagnosis, mutual interference prevention, and external diagnosis. Its robust IP65 protection structure makes it suitable for demanding industrial environments.
