Turck NI20-K40SR-VP4X2 Inductive Proximity Switch

The TURCK NI20-K40SR-VP4X2 Inductive Proximity Switch delivers non-contact detection of metallic objects with a 20 mm nominal sensing distance, housed in a smooth Ø40 mm ABS cylindrical enclosure rated IP67 for harsh industrial environments, and featuring extended sensing distance technology with a complementary PNP output for flexible control integration. It offers two cable-entry points (axial and radial) for installation ease, dual LED indicators for quick status checks, 10–65 VDC supply, up to 200 mA load, and a 100 Hz switching frequency, designed as a non-embeddable inductive sensor suitable for machine positioning and automation control. This sensor is commonly used in conveyors, material handling, packaging lines, steel processing, pallet conveyors, transfer stations, and machine tools, making it a fitting replacement in automation retrofits and OEM equipment repairs; common replacements include TURCK NI20-CP40-VP4X2-B1141 and NI20-CK40-AP6X2-H1141.
