SICK WTB8-P2231 Industrial Photoelectric Sensor

The SICK WTB8-P2231 is a compact background-suppressing photoelectric sensor in the W8 family, offering reliable non-contact detection in a small, rectangular 11 mm × 31 mm × 20 mm housing. It detects targets at a range of 30 to 300 mm using a visible red light (650 nm) with a 20 mm spot at 300 mm, and it is powered from 10 to 30 V DC with ±10% ripple. Adjustment is via a four-turn potentiometer for precise switching thresholds, and the device is designed to suppress background reflections for stable sensing in cluttered environments. The part (6033209) is delivered with BEF-W100-A included, making it ready for immediate integration on lines such as conveyors and packaging systems where small parts require accurate presence sensing. Life expectancy is up to 100,000 hours at +25 °C, and the outputs are protected against short circuits in protected networks (up to 8 A).
