The 120 mm maximum sensing range with a 4 mm minimum means it reliably detects objects from nearly touching the lens out to 120 mm — useful for small-part presence on conveyors or fill-level detection where the background is farther than the target. Background suppression cuts false triggers from shiny or dark backgrounds behind the target. The PinPoint LED visible red light produces a small, intense spot that makes alignment visible to the naked eye — no laser safety paperwork needed, but still precise enough for 500 µs response time on fast-moving parts. That 500 µs response means it can catch objects moving past at several meters per second, suitable for high-speed packaging or sorting lines. Rated IP66, IP67, IP68, and IP69K — the IP69K rating specifically means it withstands high-pressure, high-temperature washdown cycles common in food-and-beverage and pharmaceutical lines. The sensor body and optics survive caustic wash chemicals at 80 °C and 80–100 bar, so it can be mounted directly in washdown zones without a protective housing. The 15.25 mm wide, 44.9 mm tall, 22.2 mm deep housing fits into tight machine frames where every millimeter counts — think end-of-arm tooling, small transfer stations, or multi-sensor arrays on a 20 mm grid. The M8 4-pin connector keeps wiring clean; no cable gland to torque, just plug and go. PNP output is the standard for most PLC input cards — sourcing 100 mA at 10–30 VDC drives small contactors, solenoid valves, or indicator lights directly. Light/Dark ON switching is selectable via the teach-in or wiring — common for both presence (light ON) and absence (dark ON) detection. The wide operating temperature range from -30 °C to +70 °C covers cold storage and hot washdown zones without derating.","metaTitle":"SICK WTB4S-3P2232V Photoelectric Proximity Sensor, 120 mm, P","metaDescription":"SICK WTB4S-3P2232V miniature photoelectric proximity sensor with background suppression. 120 mm sensing range, PNP output, 500 µs response, IP69K.

It also has a narrower temperature range (-10 °C to +50 °C) and lower IP rating (IP66/IP67 only). It uses the same M8 4-pin connector and PNP output, so wiring is compatible, but the 12.2 mm width means it is narrower than the 15.25 mm WTB4S-3P2232V — a panel cutout or bracket designed for the wider sensor may need a shim or adapter."},{"question":"What are the key dimensions for panel cutout planning?","answer":"Width is 15.25 mm, height is 44.9 mm, and length is 22.2 mm.
