Turck M12 Inductive Sensor PNP

The Turck BI2-M12-AP6X/S120 is a flush-mount inductive proximity sensor built for industrial automation. It suits maintenance engineers and panel builders who need reliable metal detection in a compact threaded barrel. The sensor operates on 10 to 30 VDC with a PNP normally-open output. It is not for applications requiring analogue output or non-flush mounting.

Rated switching distance 2 mm

The single specification that decides fit is the 2 mm rated switching distance. This defines the maximum reliable detection range for standard steel targets. A larger gap or smaller target will cause missed detections. The fixed distance cannot be adjusted in the field.

M12 × 1 chrome-plated brass housing

The sensor threads into an M12 × 1 cutout and seals with its chrome-plated brass barrel. It needs a 3-wire DC supply and a cable route rated for up to 120 °C ambient temperature. The flush design lets surrounding metal sit level with the sensing face, freeing panel space that a non-flush sensor would occupy.

Questions about this item

How does the 2 mm rated switching distance behave once the sensor is mounted flush in metal?

The 2 mm switching distance is calibrated for flush mounting in metal, so the sensor detects a target at that distance when installed correctly in a threaded M12 × 1 hole.

What does the PNP output on a 10…30 VDC supply actually deliver to the control input?

The PNP output switches the positive supply rail to the load, giving a high signal up to the applied voltage between 10 V and 30 VDC when the target is present.

What clearance and thread do I need to fit the M12 × 1 chrome-plated brass barrel?

Drill a standard M12 × 1 threaded hole; the flush-mount barrel seats fully into metal with its chrome-plated brass housing and 100 g weight.
