Cylindrical M30 inductive sensor
The Sick IM30-20NPO-ZC1 is a cylindrical inductive proximity sensor with an M30 x 1.5 thread and a 20 mm sensing range. It features a PNP normally closed output on a 4-pin M12 male connector. The nickel-plated brass housing measures 76 mm in length with a 38 mm thread length and carries an IP67 enclosure rating.
Suited for DC automation needing NC logic
This unit suits 10–30 V DC control systems that require a normally closed signal with 150 Hz switching frequency. Its non-flush mounting and 400 mA continuous current fit standard industrial sensing tasks. Buyers who need a normally open output function or a flush mounting style should look at alternative sensor configurations.
Integrates into 3-wire DC sensor circuits
The sensor connects via a 4-pin M12 plug into a 3-wire DC supply, drawing 10 mA with short-circuit, reverse polarity and power-up pulse protection. A 100 ms power-up delay and 2–15 % hysteresis support stable operation from –25 °C to +70 °C. Maximum tightening torque is 60 Nm for secure metal housing installation.
Highlights
- 20 mm sensing range detects targets reliably
- PNP NC output simplifies control wiring
- M12 4-pin connector enables quick installation
- IP67 rating withstands harsh environments
- M30 x 1.5 thread fits standard mounting holes

Questions about this item
What supply voltage must already be present for the IM30-20NPO-ZC1 to operate?
The sensor requires a DC supply between 10 V and 30 V with ripple no greater than 10 %.
Will the 20 mm sensing range and 150 Hz switching frequency remain reliable when mounted beside legacy 30 g shock-rated equipment?
Yes, the sensor is rated for 30 g shock at 11 ms and vibration from 10 to 55 Hz at 1 mm, matching typical legacy specs.
How can I confirm the PNP NC output is functioning correctly after wiring the M12 4-pin connector?
Apply a target at 20 mm; the output should go low (NC) with a voltage drop below 1 V while drawing up to 400 mA continuous current.
