Inductive sensor 35 mm range

The Turck NI35-CK40-AP6X2-H1141 is a rectangular inductive proximity sensor with a rated switching distance of 35 mm. It operates on 10 to 30 VDC supply voltage and provides a PNP normally open output. The sensor suits automation engineers and maintenance technicians who need reliable non-contact metal detection.

DC 3-wire M12 connector limits

The sensor uses a DC 3-wire interface with an M12 × 1 male connector for electrical connection. This standard connector simplifies installation in control cabinets and field wiring. The fixed 10 to 30 VDC operating window means the unit cannot be used with AC supplies or voltages outside this range.

35 mm sensing range headroom

The 35 mm rated switching distance offers a large sensing range for a rectangular CK40 housing measuring 65 × 40 × 40 mm. Non-flush mounting is required to achieve this distance, so metal near the active face will reduce the effective range. The variable orientation of the active face in five directions helps optimise the detection zone for the application.

Questions about this item

Which sensing-range version should I choose for this rectangular CK40 sensor?

The NI35-CK40-AP6X2-H1141 has a single rated switching distance of 35 mm, so no alternative range versions exist for this model.

What does the 35 mm switching distance mean when the sensor is mounted in a machine?

It detects metal targets reliably up to 35 mm away when mounted non-flush, with the active face orientable in five directions for flexible positioning.

How does the M12 × 1 connector limit voltage and wiring in practice?

The 3-wire DC connector carries 10…30 VDC to the PNP NO output, so the supply must stay within that range and the cable must match the M12 pinout.
