Industrial inductive sensor NPN

The Turck NI35U-CK40-AN6X2-H1141 is a rectangular inductive sensor with a 35 mm rated switching distance. It operates on 10…30 VDC with a NPN normally open output and connects via an M12 × 1 male connector. The non-flush mount design suits automation and machine-building applications.

Sustained operation stability

Auto-compensation protects against pre-attenuation during continuous duty cycles. The uprox®+ factor 1 gives equal switching distance on all metals without recalibration. IP68 protection and resistance to magnetic fields maintain signal integrity in harsh industrial environments.

35 mm switching distance decides fit

This single specification determines whether the sensor reaches the target across the required air gap. A shorter distance misses the workpiece; a longer one risks false triggers from nearby metal structures. Verify the 35 mm rating matches your mechanical layout before ordering.

Questions about this item

How much heat does the NI35U-CK40-AN6X2-H1141 generate when running all day at 30 VDC?

The sensor draws only the current required by its NPN output load; at 30 VDC the internal dissipation is negligible, so it stays cool inside the PBT-GF20-V0 housing.

What power supply and cable must I already have to connect the M12 × 1 male connector?

You need a 10…30 VDC source and a standard 3-wire M12 female cordset wired for NPN NO switching.

Will the factor-1 sensing and magnetic-field resistance work reliably next to older steel machinery and welders?

Yes — factor 1 gives the same 35 mm switching distance on all metals, and the uprox®+ design ignores strong magnetic fields from nearby equipment.
