It runs on a 30 V DC supply and draws a maximum load current of 0.1 A. The visible red LED light source and potentiometer adjustment make it straightforward to align and set on a conveyor or pick-and-place station. The M12 male connector (4-pin) keeps wiring clean — mates directly to a standard M12 cordset without a separate junction box. The 20 mm sensing range is a short-range fixed-focus detection zone — suited for close-proximity object presence on a conveyor, not for long-range through-beam or retroreflective applications. The PNP (sourcing) output is the standard for most PLC input cards in North America and Europe; if your controller expects NPN (sinking), this sensor will not interface without a converter or a different model. Operating temperature from -40 to +60 °C covers freezer-to-warehouse extremes.","metaTitle":"SICK WT12-P4381 Photoelectric Proximity Sensor, PNP, 20 mm,","metaDescription":"SICK WT12-P4381 photoelectric proximity sensor with PNP output, 20 mm sensing range, IP67 metal housing, M12 connector.
