Long-Range Background Suppression 42BT and 42BC Photoelectric Sensors • Adjustable 1 m and 2 m range background suppression • Slim flat pack housing design • Infrared LED or red LED • Selectable L.O. and D.O. • Dual (PNP and NPN) outputs • AC/DC relay output models (42BC) • Sensing the Target While Ignoring the Background • Background suppression sensors are designed for applications requiring the sensor to see a target very close to a reflective background. • Background suppression is particularly effective when the target and background have similar reflectivities or when dark targets are to be sensed against a lighter, more reflective background. • These long range models offer high background suppression performance at sensing ranges up to 2 m (6.6 ft).
