The Autonics BWP20-08P Slim Plastic Body Area Sensor is engineered with a through-beam sensing type, covering a reliable detection range from 0.1 to 5 meters. Equipped with 8 optical axes at a 20mm pitch, it ensures accurate detection of opaque targets as small as Ø30mm. The infrared LED (850nm modulated) provides stable operation even under ambient illumination up to 10,000 lux.

Powered by 12–24VDC Β±10%, this sensor delivers PNP open collector outputs with selectable Light ON/Dark ON modes, making it easy to integrate with modern PLC systems. Its fast 6ms response time supports high-speed production environments, while the polycarbonate/ABS body offers durability with a compact footprint. The IP40 protection rating, 3-meter cable, and lightweight design allow quick installation in clean, controlled environments.

With a sensing height of 140mm and a total length of 190mm, the BWP20-08P is an optimal choice for space-constrained machinery. For more models, visit the Autonics Sensors & Controllers page.

This sensor is ideal for assembly line quality checks, small-part detection in packaging machines, and safety verification in workstation automation. It enhances operational efficiency in pick-and-place units, material positioning systems, and inspection jigs. Maintenance teams value it for its plug-and-play integration and minimal alignment needs. Engineers rely on this sensor for dependable, repeatable detection in compact setups, especially when deploying the Autonics BWP20-08P.
