The Autonics BWP20-20 Slim Plastic Body Area Sensor features a robust through-beam sensing type with a detection range of 0.1 to 5 meters, making it ideal for stable detection of opaque targets as small as Ø30 mm. It uses a modulated Infrared LED (850 nm) to minimize false triggering from ambient light, maintaining accuracy even under sunlight up to 10,000 lx.
With a 20 mm optical axis pitch and 20 optical axes, the sensor offers a 380 mm sensing height for broad coverage. Its fast 6 ms response time supports high-speed conveyor and assembly line operations. Powered by 12–24 VDC ±10% with ripple P-P of max. 10%, the BWP20-20 provides stable performance with NPN open collector output and selectable Light ON/Dark ON operation modes.
Built with a durable polycarbonate/ABS housing and an IP40 protection structure, it is designed for reliable performance in controlled industrial environments. The 3 m Ø3.5 mm 4-wire cable simplifies wiring, while its lightweight body (approx. 680 g) ensures easy mounting. More details on Autonics sensing solutions are available at Autonics Sensors & Controllers.
This sensor is ideal for assembly line monitoring, automated packaging, and pick-and-place systems where precise detection is essential. Its compact body makes it perfect for space-limited machines, and its fast response supports high-speed production lines. Engineers prefer it for consistent performance in controlled environments, especially when using the Autonics BWP20-20.
