The Autonics BW40-08 uses a through-beam type detection system with a sensing range of 0.1 to 7 meters and infrared LED light at 850nm. Its 40mm optical axis pitch and 8 optical axes provide accurate detection across wider zones. Operating on 12β24VDC with a tolerance of Β±10%, it supports NPN open collector output and Light ON operation. The maximum response time of 10ms ensures quick reaction in high-speed applications. Built with a durable aluminum case and protected by an IP65 enclosure, the sensor withstands challenging industrial environments. It functions reliably in temperatures between -10Β°C to 55Β°C and tolerates ambient light up to 10,000 lux. A 300mm cable with M12 connector enables quick and secure integration. Designed to detect opaque objects as small as 50mm, it is a trusted choice for automated systems requiring stable and accurate area detection.
