Balluff BOS 18M-WS-7PB-B1-L-03 Sensor

Balluff BOS 18M-WS-7PB-B1-L-03 is a cylindrical M18 diffuse optical sensor (Ø18 x 88 mm) that detects objects by infrared diffuse reflection, delivering reliable presence sensing along conveyors and packing lines. The device features a brass, nickel-plated housing with a PMMA active surface and a divergent IR beam, offering a 0–200 mm sensing range. It is powered from 20–250 VAC and provides a normally open output via a thyristor plus diode-bridge interface, making it suitable for simple AC sensing circuits. The unit is equipped with a 3.0 m PVC cable for flexible mounting in tight industrial spaces, and its diffuse sensing configuration suits applications where target surfaces reflect light back to the sensor. Balluff’s 18M series emphasizes rugged cylindrical construction for industrial environments, with this specific BOS002M variant verified for compatibility in standard automation layouts and packaging or material-handling setups that require compact, reliable optical detection. Use cases include detecting the presence or absence of parts on a conveyor, monitoring bin or chute loads, and confirming workflow progress in automated manufacturing lines where a robust M18 diffuse sensor is advantageous.
