Turck NI8-M18E-LIU-H1141 Inductive Proximity Sensor

The TURCK NI8-M18E-LIU-H1141 is an inductive proximity sensor with an analog output designed for continuous position and distance measurement of metallic targets in industrial automation. It delivers a linear analog signal via a 4-wire interface (0–10 VDC or 0–20 mA) from a 15–30 VDC supply, enabling precise feedback for PLCs, HMIs, and industrial controllers. Housed in a compact M18 x 1 threaded barrel with a chrome-plated brass body and non‑flush mounting, it features an 1–5 mm measuring range and a rated operating distance of 8 mm, with an M12 x 1 4-pin connector and a 100 Hz measuring frequency. The unit is rated IP67 and operates from −25°C to +70°C, drawing a maximum no-load current of 8 mA. Key capabilities include linear analog output, continuous position sensing, and short-circuit protection in a compact M18 design. Commonly used for continuous position, distance, and level measurement, it’s well suited for conveyor systems, material handling equipment, hydraulic machinery, packaging lines, and automated manufacturing processes requiring analog feedback for positioning and process control. This sensor is frequently selected by maintenance teams, OEM machine builders, and system integrators for sensor replacement, upgrades, retrofits, and precision control installations.
