Industrial Inductive Sensor PNP

The Turck Ni50U-CK40-AP6X2-H1141 is a rectangular inductive proximity sensor with a 40 mm height and PNP normally open output. It operates on 10…30 VDC through a 3-wire DC connection and terminates in an M12 x 1 male connector. Automation engineers and machine builders use it for reliable non-contact metal detection in industrial environments.

Sustained Operation With Auto-Compensation

Auto-compensation protects the sensor against pre-attenuation effects that can develop during continuous operation near metal backgrounds. The factor 1 rating for all metals ensures consistent switching distance across ferrous and non-ferrous targets without recalibration. Resistance to magnetic fields prevents false triggering from nearby welding equipment or motors. High luminance corner LEDs give clear indication of supply voltage and switching state from any viewing angle.

IP68 Sealed M12 Interface Limits

The M12 x 1 male connector and IP68 protection class allow permanent immersion and high-pressure washdown without ingress. Partial embeddability permits flush mounting in metal brackets while maintaining the increased switching distance. The PBT-GF30-V0 housing withstands aggressive cleaning agents and mechanical impact. Variable orientation of the active face in five directions provides mounting flexibility within the constraints of the rectangular 40 mm form factor.

Questions about this item

How much power does the Ni50U-CK40-AP6X2-H1141 draw when operating continuously on a 10…30 VDC supply?

The sensor runs on a DC 3-wire connection from 10 to 30 VDC; its own current draw is very low because it only powers the detection circuit and the PNP output stage.

What power supply and cabling must I already have to install the Ni50U-CK40-AP6X2-H1141?

You need a 10…30 VDC source and an M12 x 1 female cordset to match the sensor’s male connector; the sensor itself is a 3-wire PNP device with an NO contact.

Will the Ni50U-CK40-AP6X2-H1141 work reliably alongside older machinery that produces strong magnetic fields?

Yes, the sensor is rated resistant to magnetic fields and includes auto-compensation that protects against pre-attenuation, so it maintains stable switching near welders or large motors.
