The Autonics BW20-32 is a high-performance General Purpose Area Sensor designed with a robust through-beam sensing method, providing a reliable detection range from 0.1 to 7 meters. Its infrared LED light source (850nm modulated) and 32 optical axes with a 20mm pitch enable precise detection of opaque objects with a minimum diameter of 30mm, even under ambient illumination up to 10,000 lux. This ensures consistent operation in both brightly lit and dim environments.
Built to operate on 12β24VDC Β±10%, the BW20-32 supports NPN open collector outputs and Light ON mode, making it compatible with modern PLC and automation systems. The IP65-rated aluminum housing, coupled with an acrylic front cover, protects the sensor from dust, moisture, and mechanical wear. With a fast 10ms response time and M12 cable connector, installation is straightforward, minimizing downtime during setup or replacement.
Its sensing height of 620mm makes it suitable for wide detection zones, while its lightweight 1.4kg body ensures easy mounting on conveyor systems, safety gates, and inspection stations. For more Autonics industrial solutions, visit the Autonics Sensors & Controllers page.
The BW20-32 is widely used in industrial conveyor systems for product presence detection, in packaging lines for missing-item inspection, and in automated storage systems for entry/exit monitoring. It is also effective for elevator door safety, robotic work cell protection, and quality control in assembly lines. Its reliability under variable temperatures and lighting conditions makes it a preferred choice for both new installations and retrofit projects. Engineers across logistics, manufacturing, and automotive sectors trust the Autonics BW20-32 for these critical applications.
