Industrial proximity sensor for metal detection
The Sick IM30-20BPS-NC1 is an inductive proximity sensor designed for automated machinery and process control. It detects metal targets at a 20 mm sensing range with a 100 Hz switching frequency. The PNP normally-open output operates on 10 to 30 V DC supply voltage. It suits applications requiring non-contact position sensing in harsh environments.
DC supply limits and switching constraints
The sensor requires a 10 to 30 V DC supply with a maximum 20 % ripple. Voltage drop across the output is 2 V at a continuous current of 200 mA. Current consumption is 10 mA with a 40 ms power-up delay. Hysteresis ranges from 1 % to 15 % and reproducibility is 5 %. Temperature drift of the sensing range is 10 %. Short-circuit, reverse polarity and power-up pulse protection are included.
Stainless steel housing with M12 connector
The cylindrical housing uses V4A stainless steel (1.4435, 316L) for both body and sensing face. Thread size is M30 x 1.5 with a 42 mm thread length and 150 Nm maximum tightening torque. Overall housing length is 63.5 mm. Connection is via a 4-pin M12 male connector. Enclosure ratings IP68 and IP69K resist high-pressure washdown and immersion. Operating temperature spans –25 °C to +85 °C. Shock resistance is 30 g for 11 ms and vibration resistance covers 10 to 55 Hz at 1 mm amplitude.

Questions about this item
Should I pick the flush-mount M30 version with 20 mm range or a non-flush alternative?
The IM30-20BPS-NC1 is a flush-mount M30 sensor with a 20 mm nominal range and 16.2 mm safe range; choose it when you need the metal face to sit level with the mounting surface.
What does the 20 mm sensing range mean once the sensor is installed in a machine?
The sensor reliably detects metal targets up to 16.2 mm away in normal operation; the 20 mm nominal figure is the maximum under ideal conditions.
What does the M12 4-pin connector cap in practice?
The M12 4-pin male connector carries the 10–30 V DC supply and the PNP normally-open output, limiting the switching current to 200 mA continuous.
