Pro-Range RM30 NPN Inductive Proximity Sensor 10mm Detection DC6-36V Shielded M30 Thread

Shielded (or flush-mount) sensors have a metallic ring that confines the electromagnetic field to the sensor's face, allowing them to be installed flush with a metal surface without causing interference or false triggers. Non-shielded sensors require a clearance around the sensing face to operate correctly. This RM30 model is shielded.

This sensor operates on a wide-range DC supply from 6V to 36V. The nominal operating voltage is 24V DC. Ensure your power source can provide stable voltage within this range and can handle the sensor's quiescent current and the load current of your connected device (PLC input, relay, etc.).

Connect the brown wire to your positive DC supply (6-36V), the blue wire to the DC common (0V), and the black wire is the switched NPN output. When a metal target is detected within range, the black wire will switch to ground (sinking current), completing the circuit to your load, which should be connected between the positive supply and the black wire.

Inductive sensors detect all conductive metals, but the sensing distance varies. Ferrous metals (like steel and iron) are detected at the full nominal distance (10mm). Non-ferrous metals (like aluminum, copper, brass) have a reduced sensing distance, typically 30-60% of the nominal value, due to their lower permeability.

Yes, with its IP67 rating, the sensor is protected against temporary immersion in water (up to 1m for 30 minutes) and is completely dust-tight. It is suitable for use in damp, dusty, or oily industrial environments, but is not designed for continuous submersion or high-pressure water jets.
