Industrial M12 inductive sensor

The Turck BI4U-MT12-AN6X-H1141 is a threaded-barrel proximity switch built for factory automation and machine builders who need reliable metal detection. Its factor-one response treats all metals equally, so a single sensor covers ferrous and non-ferrous targets without recalibration. The NPN normally-open output suits standard 10 to 30 VDC control circuits. A PTFE-coated brass housing resists weld spatter and chemical splash in harsh production cells.

IP68 sealing and magnetic immunity

The housing meets IP68 ingress protection, allowing permanent submersion and high-pressure wash-down without seal failure. Internal circuitry is hardened against strong magnetic fields from welding guns or large motors, preventing false triggers. Power draw stays low on 10 to 30 VDC supplies, and the solid-state output generates no audible noise or contact bounce during rapid cycling.

M12 quick-disconnect and uprox+ benefits

A four-pin M12 male connector enables tool-free cable swaps and reduces installation time on conveyors or robotic arms. The uprox+ architecture delivers an extended switching distance while maintaining flush-mount capability in metal brackets. PTFE coating prevents debris build-up on the sensing face, cutting cleaning intervals. Supplied as a single unit in a box with a three-year parts and one-year labour guarantee.

Questions about this item

How do I install the M12 threaded barrel sensor and what step is often missed?

Screw the M12 × 1 barrel into a flush mounting hole and tighten to the recommended torque; the step often missed is verifying the PTFE-coated face sits perfectly flush with the surface so the 4 mm rated switching distance is achieved.

What maintenance or replacement will the sensor need over time?

The PTFE-coated brass housing resists weld spatter and magnetic fields, so no routine cleaning is required; if the NPN output fails after the three-year parts coverage period, replace the complete unit.

What limit appears first during continuous 10…30 VDC operation?

The IP68-rated housing handles sustained immersion and temperature cycling, so the first practical limit is the NPN output’s maximum load current — stay within its rated switching frequency to avoid signal loss.
