The Autonics BW40-04 operates using a General Purpose Area Sensors and provides reliable detection over a 0.1 to 7-meter range. It emits infrared LED light at 850nm, modulated to improve accuracy and minimize interference. With just 4 optical axes spaced at a 40mm pitch, this model is suited for narrow sensing areas where precise control is needed. Its 12β24VDC power input (Β±10% tolerance) and NPN open collector output in Light ON mode make it compatible with most PLCs and logic controllers. The sensor body is constructed with a rugged aluminum case and sealed to an IP65 protection level, making it suitable for dusty or wet environments. It offers a sensing height of 120mm and supports minimum detectable object sizes of Γ50mm, with a fast 10ms response time that supports dynamic automation tasks. Its M12 connector type and 300mm pre-wired cable simplify installation. It operates reliably from -10Β°C to 55Β°C and resists ambient light up to 10,000 lux, making the BW40-04 a preferred solution in tightly constrained or high-speed systems.
