The SICK IM18-12NNO-ZQD Inductive Proximity Sensor is a compact M18-threaded switch with a 12 mm sensing range and non-flush mounting, part of SICK’s IM Standard series. It operates on 10–30 V DC with a 3‑wire NPN normally open output, rated for up to 400 mA, and ships with a 1 m M12 4‑pin cable. Key specs include a 300 Hz switching frequency, a response delay of 100 ms, voltage drop ≤ 1 V, ripple ≤ 10%, hysteresis 2–15%, and reproducibility ≤ 5%. The housing is Ø18 mm (M18×1), IP67 protected, includes toothed washers, and is designed for DC sensing in non-flush installations.
