Turck NI20-CP40-VP4X2-B1141 Inductive Proximity Sensor

The TURCK NI20-CP40-VP4X2-B1141 Inductive Sensor delivers non-contact detection of metallic objects over a 20 mm nominal sensing distance, using UPROX technology in a rectangular CP40 housing for reliable metal sensing across different alloys. It outputs a PNP transistor signal with a complementary NO/NC function, operates on 10–65 VDC, and tolerates up to 200 mA with a switching frequency of 150 Hz. The device measures 114 × 40 × 40 mm, uses a PBT-GF30-V0 reinforced plastic CP40 housing, supports flush mounting, and is IP67 rated, featuring a 4-pin B1141 connector and dual high-visibility status LEDs. Ideal for conveyor systems, automotive assembly lines, material handling equipment, transfer systems, and heavy industrial machinery requiring long-range metal detection and accurate position feedback; common replacements include TURCK NI40U-CP40-VP4X2 and BI15-CP40-VP4X2.
