Product Specification
| Description | Accelerometers RoHS | Mfr. Part # | BW40-20 |
| Model Number | BW40-20 |
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. High-brightness LEDs on both the emitter and receiver ensure easy recognition from various angles and distances. This sensor includes advanced functions like self-diagnosis, mutual interference prevention, and external diagnosis, all housed within a robust IP65 protected structure.
