It detects objects at a set distance between 4 mm and 120 mm, ignoring background surfaces beyond that point — that's the background suppression function, which eliminates false triggers from conveyors or machine frames behind the target. The 120 mm maximum sensing distance means it's sized for close-range detection on small parts or packaging lines where you need a defined cutoff. The 500 µs response time keeps up with fast-moving items on a pick-and-place or bottling line. Rated IP66, IP67, IP68, and IP69K — the IP69K rating is the key one here: it withstands high-pressure, high-temperature washdown cycles common in food-and-beverage and pharmaceutical lines. The sensor body and optics are sealed for that duty, not just splash protection. The housing measures 15.25 mm wide by 63.2 mm tall by 22.15 mm deep. That's a compact footprint for tight spaces on a bracket or machine frame. Termination is via an M8 4-pin connector — no cable gland to manage, but you'll need a mating cordset with the same pinout. Output is PNP (sourcing), switching light-on or dark-on selectable. Supply range is 10 V to 30 V DC, drawing up to 100 mA load current. The visible red PinPoint LED makes alignment visible during setup — you see the spot on the target.","metaTitle":"SICK WTB4S-3P5232H Photoelectric Proximity Sensor, 120 mm, P","metaDescription":"SICK WTB4S-3P5232H miniature photoelectric proximity sensor with background suppression. 120 mm range, PNP output, 500 µs response, IP69K.
