Turck Ni100U-K90SR-VP4X2 Inductive Proximity Sensor

The TURCK NI100U-K90SR-VP4X2 is a rectangular-block inductive sensor that leverages Uprox Factor 1 technology to achieve long-range non-contact metal detection across standard industrial targets. It has a nominal sensing distance of 100 mm and a PNP transistor output with a complementary NO/NC function, powered from 10–65 VDC and capable of switching up to 200 mA at up to 250 Hz, wired via a 4-pin M12 connector in a PBT-GF30 reinforced housing measuring 130 mm × 75 mm × 60 mm and IP68 rated for harsh environments. Designed for demanding automation and machine control, it tolerates -30°C to +85°C and delivers equal sensing distances for steel, aluminum, brass, and copper targets, making it suitable for conveyors, steel mills, pallet handling, robotic cells, and automated production equipment where extended sensing range is required. Common replacements include the NI75U-Q80-VP4X2-H1141, NI50U-CK40-VP4X2-H1141, and BI50U-Q80-AP6X2-H1141.
