It switches at 1 kHz with ±0.1 mm repeatability, so it catches fast-acting cylinder strokes without missing a position signal. Rated IP67, the zinc die-cast housing and sealed M8 connector hold up on washdown lines or in wet cabinet environments. ## Electrical integration notes Operates on 10-30 V DC with a PNP normally-open output rated for 200 mA continuous — enough to drive a small PLC input or a 24 VDC relay coil directly. Switching capacity is 6 W, so keep the load draw under 200 mA at 24 V to stay within the inductive switch's safe operating area. The M8 3-pin connector is standard for Festo SMT-series sensors; wiring is pin 1 (brown) +24V, pin 3 (blue) 0V, pin 4 (black) PNP output.","metaTitle":"Festo SMT-3-PS-SL-LED-24B Inductive Proximity Switch, PNP, 2","metaDescription":"Festo SMT-3-PS-SL-LED-24B inductive proximity switch, PNP normally open, 10-30 V DC, 200 mA, IP67, M8 3-pin.
