Industrial Inductive Sensor NPN M18

The Turck NI12U-S18-AN6X-H1141 is a non-flush inductive proximity sensor with a threaded M18 × 1 barrel. It detects all metals at a rated switching distance of 12 mm with Factor 1 consistency. The PBT-GF30 housing meets IP68 protection and resists magnetic fields. A 10…30 VDC supply powers the NPN normally-open output via an M12 × 1 male connector.

Suited For Automated Metal Detection

This sensor suits automation engineers who need reliable, non-flush metal sensing at 12 mm range in harsh environments. Its IP68 rating and magnetic-field immunity fit wash-down and welding zones. Builders requiring flush mounting, flush sensing distances, or analogue output should look at alternative sensor designs.

Key Spec: 12 mm Non-Flush Sensing Range

The 12 mm rated switching distance with Factor 1 for all metals defines the detection envelope. Non-flush mounting means the sensing face must project clear of surrounding metal. Verify that the 12 mm range and non-flush mechanical requirement match the application before purchase.

Questions about this item

How far will the 12 mm sensing range actually detect metal in a real installation?

The sensor switches at 12 mm for every metal type because its Factor 1 design gives the same distance on steel, aluminium, copper or brass without recalibration.

What does the M12 × 1 connector limit in terms of voltage and wiring?

The 4-pin M12 plug carries 10–30 VDC on a 3-wire NPN output, so the cable assembly must match that pinout and voltage window.

What clearance does the M18 × 1 threaded barrel need for non-flush mounting?

Because it mounts non-flush in an M18 × 1 hole, the plastic PBT-GF30 barrel requires a clear zone around the sensing face so metal brackets do not cause pre-attenuation.
