M18 Inductive Sensor for Industrial Detection

The Turck BC5-S18-AP4X is a flush-mount proximity switch with a 5 mm rated switching distance. It suits automation engineers who need reliable metal detection on conveyors or machine frames. The PNP normally-open output integrates directly into 10–65 VDC control circuits. Buyers who require analogue output or NPN switching should select a different model.

Stable Switching Across the Full Voltage Range

The sensor maintains consistent trigger points from 10 VDC up to 65 VDC without recalibration. Its fine-adjustment potentiometer allows precise setting of the operating distance during commissioning. The 3-wire DC design prevents leakage-current errors that can plague 2-wire alternatives. Installers who need diagnostic feedback or IO-Link communication will not find those functions here.

PA12-GF30 Housing With Integral Cable

The threaded M18 × 1 barrel is moulded from glass-filled PA12 and PEI, resisting oils, coolants and mechanical impact. A fixed cable tail exits the rear, eliminating a separate connector that could loosen under vibration. The 110 g weight keeps mounting brackets light while the cULus approval supports North American panel builds. Users who prefer quick-disconnect plugs must choose a variant with an M12 connector.

Questions about this item

How much heat or noise does the M18 inductive sensor generate when running continuously?

The solid-state PNP output has no moving parts, so the sensor produces no audible noise and negligible heat during all-day operation.

What power supply and wiring must I already have to install this sensor?

You need a 10…65 VDC source and a three-wire cable run to connect the sensor’s PNP output to your control input.

Will the M18 × 1 thread and 5 mm switching distance work with my existing mounting brackets and targets?

The M18 × 1 threaded barrel fits standard M18 brackets, and the 5 mm flush-rated switching distance matches common metal targets used with earlier M18 sensors.
