Turck M18 Inductive Sensor

The Turck BI8U-M18-AP6X is a flush-mountable inductive proximity switch with an M18 × 1 threaded barrel. It suits electricians and automation engineers who need reliable metal detection at an 8 mm rated switching distance. The chrome-plated brass housing meets IP68 protection and resists magnetic fields, while Factor 1 performance gives equal sensing on all metals. Supplied as a single unit in a box.

Pre-installation Checks

Verify that the control circuit operates on DC voltage between 10 and 30 VDC and accepts a three-wire PNP normally-open output. Confirm the mounting location allows a flush fit for the M18 threaded barrel and that cable routing can reach the connection point. The sensor weighs 121 g and carries the eCl@ss code 27270101 for procurement systems.

Thermals Noise and Power Draw

The solid-state design has no moving parts, so it runs silently and generates negligible heat during normal operation. Power consumption stays low within the 10…30 VDC supply range. The IP68-rated metal housing handles harsh environments without derating, and the uprox®+ electronics maintain stable switching despite strong magnetic fields.

Questions about this item

Does the BI8U-M18-AP6X come with mounting hardware or must I buy nuts and washers separately?

The sensor has an M18 × 1 threaded barrel and is designed for flush mounting; mounting nuts and washers are not included and must be sourced separately.

Should I choose the PNP NO version or is another output type available for this model?

This model is supplied only as a 3-wire DC PNP normally-open sensor operating from 10 to 30 VDC; no other output configuration exists for the BI8U-M18-AP6X.

What does the 8 mm rated switching distance mean when the sensor is installed in a steel machine frame?

The 8 mm rating is achieved with the uprox®+ Factor 1 technology, so the full distance applies to all metals including steel without reduction.
