Turck BI2-M12E-AP6X-H1141 inductive sensor PNP electrician tool

Turck M12 inductive sensor PNP

The Turck BI2-M12E-AP6X-H1141 is a flush-mount inductive proximity switch in an M12 × 1 threaded barrel. It targets automation engineers and maintenance electricians who need reliable metal detection in machine-building or process applications. The sensor operates on 10…30 VDC with a PNP normally-open output and a 2 mm rated switching distance. It is supplied new in a single-unit box with manufacturer parts coverage of three years and labour coverage of one year.

DC 3-wire limits and connector fit

The DC 3-wire interface restricts use to 10…30 VDC supplies and PNP-compatible control inputs; it cannot drive NPN loads or AC circuits directly. The M12 × 1 male connector requires a matching cordset and limits cable routing to connectorised installations rather than flying leads. The 2 mm switching distance suits flush mounting in metal but will not reach targets beyond that range. The eCl@ss 27270101 classification confirms it as an inductive proximity switch for standard industrial I/O.

Chrome-plated brass housing and flush mount

The housing uses chrome-plated brass (CuZn) for corrosion resistance and mechanical durability in oily or wet environments. The flush mounting style lets the barrel sit level with surrounding metal without reducing the rated distance. At 33 g the unit adds minimal mass to brackets or tooling plates. The M12 × 1 thread and long barrel variant provide engagement depth for thick mounting plates while the connector orientation keeps wiring accessible.
