The SICK WTB9M4-3P2261 is a W9-series photoelectric proximity sensor with a 350 mm maximum sensing distance, using a PinPoint LED visible red light source. It switches at 333 µs — fast enough to catch containers on a high-speed beverage line without missing a target. The PNP output handles up to 100 mA load current, and the M8 4-pin connector keeps wiring clean on a compact 12.2 mm wide body.
Washdown-ready for wet lines
Rated IP66, IP67, and IP69K, this sensor shrugs off the spray from high-pressure washdown cycles common in food, beverage, and pharmaceutical lines. The IP69K rating means it withstands 80 °C water at 80–100 bar — no boot or housing modification needed for the filler environment.
