Industrial inductive sensor 40 mm

The Turck NI30-K40SR-FZ3X2 13425 is a non-flush inductive sensor built for industrial automation and machine monitoring. Its smooth ABS barrel measures 40 mm in diameter and weighs 192 g. The sensor suits engineers and maintenance teams who need reliable metal detection in harsh environments.

Thermals noise power draw

The unit operates without active cooling so it produces no audible noise during normal use. Power is drawn directly from the supply across a wide AC range of 20 to 250 VDC or a DC range of 10 to 300 VDC. The two-wire design keeps wiring simple and current consumption low.

Upgrade path and fit

This sensor replaces older limit switches or smaller-diameter inductive probes where a 30 mm switching distance and programmable NC/NO output are required. The jump is worth it when an application demands non-flush mounting, dual cable entries and a terminal chamber for field wiring. Buyers needing a flush-mount format or a larger sensing range should look elsewhere.

Questions about this item

How do I install the NI30-K40SR-FZ3X2 inductive sensor and which step is often missed?

Mount the smooth 40 mm ABS barrel non-flush, then wire the axial or radial cable entry into the terminal chamber; the step often missed is setting the NC/NO programmable switch before sealing the chamber.

What maintenance or replacement will the NI30-K40SR-FZ3X2 need later?

The sensor has no moving parts; only periodic checks of the terminal-chamber seals and cable glands are required to maintain the 30 mm rated switching distance.

What is the first limit that appears under sustained use of the NI30-K40SR-FZ3X2?

Continuous operation at the 250 V AC or 300 V DC upper voltage limit can accelerate insulation ageing in the ABS housing, making voltage derating the first practical constraint.
