M18 inductive sensor with PNP output

The Turck BI5U-M18E-AP6X is a flush-mount proximity switch built for industrial automation. Its M18 × 1 threaded barrel fits standard mounting holes in machine frames and conveyors. The sensor detects all metals at the same rated switching distance thanks to Factor 1 uprox®+ technology. It suits engineers specifying reliable presence detection in harsh environments.

Chrome-plated brass housing rated IP68

The metal body uses CuZn brass with a chrome-plated finish that resists coolant, oil and mechanical wear. IP68 protection allows permanent submersion and high-pressure washdown without ingress. A moulded cable connection eliminates plug failures caused by vibration or cable flex. The design also withstands strong magnetic fields from nearby welders or motors.

5 mm switching distance at 1030 VDC

The sensor operates on 10 to 30 VDC and provides a normally open PNP signal with a 5 mm rated switching distance. High switching frequency supports fast cycle times on packaging or assembly lines. Extended temperature range ensures stable operation from cold storage to hot processing zones. Buyers needing NPN logic or a longer sensing range must select a different model.

Questions about this item

What voltage range does the DC 3-wire interface support on this sensor?

The sensor operates on 10 to 30 VDC via its DC 3-wire connection.

What are the mounting dimensions and flush-mount requirement for the M18 threaded barrel?

It has an M18 × 1 threaded barrel made of chrome-plated brass and is designed for flush mounting.

How do you wire the PNP NO cable connection correctly during installation?

Connect the brown wire to positive, blue to negative, and black to the load; the PNP output switches positive to the load when metal is detected.
