Application fit

The Turck BI20U-CP40-VP4X2 1627240 inductive sensor suits automation engineers who need a rectangular proximity switch with a flush-mountable CP40 housing measuring 114 x 40 x 40 mm. Its PNP complementary output works with standard DC control circuits, while the PBT-GF30-V0 body and IP68 rating withstand harsh industrial environments. Buyers who require a cylindrical barrel format or a purely NPN output should look elsewhere.

Decisive specification

The rated switching distance is 20 mm and the uprox®+ Factor 1 design delivers that same range on every metal without correction factors. A 1065 VDC operating voltage and high switching frequency support fast cycling on conveyors or indexing tables. The terminal chamber simplifies wiring, and high-luminance corner LEDs give clear status indication from any angle.

Sustained-load behaviour

Resistance to magnetic fields prevents false triggers near welding stations or large motors, and the IP68 enclosure maintains sealing during continuous exposure to coolant, oil or high-pressure wash-down. The robust plastic housing resists impact and vibration over long production runs, while the 3-year parts coverage reflects the manufacturer's confidence in durability under steady-state industrial duty.

Questions about this item

What does the 20 mm rated switching distance mean when the sensor is installed flush in metal?

The sensor detects all metals at the same 20 mm distance without reduction factors, so a flush mount still gives the full sensing range on steel, aluminium or copper.

How does the DC 4-wire 1065 VDC complementary PNP output behave in a typical 24 VDC control circuit?

The changeover contact provides both normally-open and normally-closed PNP signals simultaneously, letting the PLC monitor presence and wire-break with a single sensor.

What mounting space and hardware does the 114 x 40 x 40 mm rectangular housing require?

The CP40 body fits a 40 mm high by 40 mm wide cut-out and 114 mm length; the active face can be rotated in nine directions so the same bracket works for side or front sensing.
