Turck BI5-M18-AD4X-H1141 Inductive Proximity Sensor

Turck BI5-M18-AD4X-H1141 is a 5 mm inductive proximity sensor that detects metallic targets non‑contactly, delivering reliable position sensing for PLC‑controlled automation on packaging lines, conveyors, assembly cells, and machine tools. The device uses a 2‑wire DC normally open output and operates from 10–65 VDC, drawing 3–100 mA with a residual current of ≤ 0.6 mA, and it switches at up to 1 kHz. It features a M12 × 1 male connector, a flush‑mountable M18 × 1 threaded barrel, a chrome‑plated brass housing, and an active PA12‑GF30 face, with an IP67 rating and a housing length of 52 mm. The sensor is designed for rugged industrial environments from -25°C to +70°C, and includes protective features such as reverse polarity protection, wire‑break protection, cyclic short‑circuit protection, and a yellow LED switching indicator. The identification number is 44145. Common replacements include BI5-M18-AP6X-H1141 and BI5-M18-AN6X-H1141, and Turck’s BI5U-M18-AD4X-H1141 is another compatible variant. This sensor provides non-contact metal object detection and position feedback for packaging equipment, conveyors, robotic assembly cells, material handling, and general manufacturing machinery where reliable sensing is required for PLC‑driven processes.
