Turck M18 Inductive Sensor PNP
This Turck Bi8U-MT18-AP6X-H1141 is a flush-mount inductive proximity sensor with a threaded M18×1 brass barrel. It operates on 10…30 VDC and provides a PNP normally-open output through an M12×1 male connector. The IP68-rated housing is PTFE-coated for chemical resistance and weld-field immunity.
Upgrade from standard factor sensors
The uprox®+ factor 1 design gives the same 8 mm switching distance on all metals without correction factors. This replaces sensors that need separate calibration for steel, aluminium or copper. The jump is worth it when a single part number must cover mixed-metal targets in welding cells or assembly lines.
Limits of the DC 3-wire M12 interface
The 3-wire DC connection supplies 10…30 VDC and carries the PNP switching signal on one conductor. Cable length and voltage drop at the load set the practical switching frequency. The M12×1 connector pins limit current to the connector rating, so high-current loads need a relay or controller.

Questions about this item
What thread size and housing diameter does the M18×1 sensor need for mounting?
The sensor uses an M18×1 threaded barrel, so the mounting hole or nut must match an 18 mm metric thread with 1 mm pitch.
How do I wire the M12×1 connector on this PNP sensor, and which mistake is common?
Connect brown to 10–30 VDC, blue to 0 V, and black to the load; a common error is swapping the black and blue wires, which inverts the output.
Will the PTFE-coated brass housing need replacement if exposed to welding spatter or coolants?
The PTFE coating resists weld spatter and most industrial coolants, so the housing typically lasts the sensor's life without replacement.
