Rectangular inductive sensor for metal detection

The Turck BI30U-CK40-AN6X2-H1141 is a rectangular inductive proximity sensor designed for industrial automation and machine-building applications. It detects all metals at the same rated switching distance thanks to Factor 1 technology. The sensor suits engineers who need reliable presence detection in harsh environments. It is not suited for applications requiring non-metallic material detection.

Rated switching distance of 30 mm

The single specification that determines fit is the 30 mm rated switching distance combined with flush mounting. This defines the maximum reliable detection range for ferrous and non-ferrous metals alike. The uprox®+ design ensures consistent performance across metal types without correction factors. Verify that your target approach and mounting geometry match this range before ordering.

M12 connector simplifies wiring

Installation uses a standard M12 × 1 male connector for quick DC 3-wire connection with NPN normally-open output. The rectangular CK40 housing measures 65 x 40 x 40 mm and mounts flush on PBT-GF20-V0 plastic. High-luminance corner LEDs give clear supply and switching status from any angle. Ensure the control system accepts NPN logic and that cable routing protects the connector from mechanical stress.

Questions about this item

How does the 30 mm rated switching distance perform when the sensor is mounted flush in a metal fixture?

The uprox®+ Factor 1 design gives the full 30 mm range on every metal target without reduction, and the flush mounting style keeps the active face level with the surrounding surface.

What does the M12 × 1 connector limit in terms of voltage and wiring?

The 4-pin M12 male connector carries the 10–30 VDC supply and the NPN normally-open output in a standard DC 3-wire pinout, cabling length is set by the mating cordset you choose.

Will the 65 × 40 × 40 mm rectangular housing fit through a standard 40 mm cut-out?

The housing is 40 mm high and 40 mm wide, so it needs a clearance at least that large; the 65 mm length extends behind the mounting plane and is secured with two screws on the 40 mm centres.
