Turck BI5U-M18-AP4X-H1141 Inductive Proximity Sensor

The Turck BI5U-M18-AP4X-H1141 is an inductive proximity sensor with a 5 mm sensing distance that delivers wear-free, non-contact metal target detection for harsh industrial environments. Built on Turck’s UPROX technology, it provides equal sensing distance across ferrous and non-ferrous metals, features Factor 1 sensing for all metals, and resists magnetic field interference, making it suitable for conveyor systems, robotic cells, packaging equipment, bottling lines, palletizers, and other automated production machinery. The device is a 3‑wire PNP normally open (NO) sensor with a 10–30 VDC supply, up to 200 mA current, and a switching frequency of up to 1.5 kHz. It features flush-mount (embeddable) mounting, an M12 4-pin male connector, and an M18 x 1 threaded barrel with a chrome-plated brass housing and a PBT sensing face, rated IP67 and operating from -30°C to +85°C. This part is CE, IEC, and RoHS compliant and lists common replacements as BI5U-M18-AP6X-H1141, BI5U-EM18-AP6X-H1141, and BI8U-M18-AP6X-H1141.
