Industrial proximity sensor

The Turck Ni3-EG08K-AN6X is an M8 threaded inductive sensor with NPN output for DC control circuits. It detects metal targets at a rated switching distance of 3 mm without physical contact. The stainless-steel barrel resists corrosion in harsh workshop or machine environments. Electricians and automation technicians use it for position sensing on conveyors, guards and tooling.

Straightforward cable installation

The sensor terminates in a three-wire DC cable for direct connection to PLC inputs or relay coils. Operating voltage ranges from 10 to 30 VDC, matching common industrial supplies. Non-flush mounting requires a clear zone around the sensing face; metal too close to the barrel causes false triggers. Secure the M8 × 1 thread with the supplied nuts and route the cable away from high-current conductors.

Compact detection with defined limits

The 3 mm switching distance suits close-range presence checks on small ferrous parts. Stainless housing grade 1.4427 SO withstands coolant splash and cleaning cycles. The NPN normally-open output switches the load to ground when metal enters the field. Beyond 3 mm the sensor cannot reliably detect targets, so applications needing longer range must choose a larger-diameter model.

Questions about this item

How can I confirm the sensor is detecting metal at the rated 3 mm switching distance after wiring it?

Apply 10…30 VDC to the brown and blue wires, bring a metal target to 3 mm from the sensing face, and verify the black output wire pulls low indicating the NO contact has closed

What comes in the box and do I need to buy a connector or mounting hardware separately?

The box contains one Ni3-EG08K-AN6X sensor with integral cable; the M8 × 1 threaded barrel mounts directly, so no separate connector is required, but nuts or brackets are not included

Should I choose the NPN or a PNP version for a PLC input that sinks current?

This model 4669700 is NPN only, so it suits sinking PLC inputs; if your controller needs a sourcing PNP signal you must select a different Turck part number
