The SICK WTB12-3F2411 is a compact reflex (diffuse) photoelectric sensor from the W12-3 family with a built-in rotary potentiometer for setting the detection threshold. It operates on 10 to 30 V DC and provides a PNP output, with an 850 nm infrared emitter and a diffuse-reflection sensing range up to 600 mm. Housed in an IP67-rated enclosure and featuring an M12 4-pin connection, this sensor is designed for rugged industrial environments. The adjustment is a 5-turn potentiometer, enabling precise tuning for varying target colors and surface textures.
