Product Identity

The Turck BI20-CK40-VP4X2-H1141 is a rectangular inductive proximity sensor designed for industrial automation tasks. It detects all metals at a rated switching distance of 20 mm with Factor 1 performance. The PNP changeover output operates on 10–65 VDC and connects via an M12 male connector. An IP68-rated PBT housing resists magnetic fields and suits flush mounting in harsh environments.

Installation Notes

The sensor housing measures 65 x 40 x 40 mm and offers variable orientation of the active face in five directions for flexible positioning. High-luminance corner LEDs provide clear indication of supply voltage and switching state from any angle. A flush mount is required to achieve the specified sensing distance. The M12 connector demands a compatible 4-wire cable assembly for the DC changeover function. No specialised tools are needed beyond standard mounting hardware.

Pre-Purchase Checks

Verify that the control system accepts a PNP changeover signal within the 10–65 VDC range. Confirm the mounting location allows a rectangular 65 x 40 x 40 mm footprint with flush installation. Ensure an M12 4-wire cable with the correct pinout is available or budgeted. The IP68 rating suits wet or dusty areas, but chemical compatibility with PBT-GF20-V0 plastic should be assessed for aggressive media. Buyers needing non-flush mounting or NPN output logic should select a different model.

Questions about this item

How can I confirm the sensor is operating correctly once installed?

The high-luminance corner LEDs show supply voltage and switching state from any viewing angle so you can verify operation visually.

What comes in the box and what must I source separately?

The box contains one BI20-CK40-VP4X2-H1141 sensor with an M12 × 1 male connector; a mating M12 cable or connector is not included and must be purchased separately.

Which version should I select for a 10–65 VDC PNP application requiring a 20 mm flush-mount range?

This single model (order number 1627216) provides a 20 mm rated switching distance, 10–65 VDC supply, complementary PNP output and flush mounting in a 40 mm rectangular housing.
