It switches PNP, light/dark selectable, and responds in 500 µs — fast enough for counting or positioning on a moderate-speed line. Housed in a compact 12.2 mm wide package with an M8 4-pin connector, it's built for tight machine frames or conveyor side-mounts where space is at a premium. The IP66/IP67/IP69K rating means it handles high-pressure washdown and caustic cleaning cycles — food-and-bev or washdown zones are right where this sensor earns its keep. Runs on 10–30 VDC and sinks 100 mA max, so it plays nicely with standard PLC inputs or a separate PNP load. The visible red beam makes alignment dead simple during setup — no guesswork on the emitter spot. Operating temperature spans -40 °C to +60 °C, covering freezer lines and hot washdown stalls without derating. The M8 connector is common on this class of sensor; replacements swap in without re-terminating the harness.","metaTitle":"SICK WL9-3P2232 Retro-Reflective Sensor, 5 m, PNP, IP69K","metaDescription":"SICK WL9-3P2232 photoelectric retro-reflective sensor. 5 m range, PNP output, 500 µs response, IP66/IP67/IP69K.
