Industrial proximity sensor NPN 20 mm
This Turck inductive sensor detects all metals at a 20 mm rated switching distance with factor-1 performance. It operates on 10–30 VDC and provides a normally open NPN output. The M30 × 1.5 chrome-plated brass barrel is rated IP68 for harsh environments. It is suited for automation engineers who need reliable non-flush metal detection.
Straightforward M12 connector installation
The sensor terminates in an M12 × 1 male connector for quick wiring to standard cordsets. Non-flush mounting requires a clear zone around the sensing face so that metal brackets do not cause false triggers. Over-tightening the lock nuts can damage the threaded barrel. The 3-wire DC circuit must be wired with the correct polarity to avoid output failure.
Verify voltage and mounting clearance
Confirm that your control system supplies 10–30 VDC and accepts an NPN sinking signal. Ensure the M30 × 1.5 thread matches the mounting hole and that enough space exists for the non-flush sensing face. Check that the IP68 rating satisfies the exposure conditions in your application. The sensor weighs 94 g if bracket loading is a concern.

Questions about this item
How do I verify the NI20U-M30-AN6X-H1141 is detecting metal at its rated 20 mm distance after wiring the M12 connector?
Apply 10…30 VDC, bring a metal target to 20 mm from the sensing face, and confirm the NPN output switches low; the LED on the barrel lights when the output is active.
What comes in the box with order number 1646150 and which mating cable must I purchase separately?
The box contains one sensor with M12 × 1 male connector; a compatible M12 female cordset is not included and must be ordered separately.
When should I choose the non-flush M30 × 1.5 version with factor 1 over a flush-mount alternative?
Select this model when you need equal 20 mm sensing on all metals and the barrel can protrude from the mounting surface; flush versions reduce range on non-ferrous targets.
