Turck BI5-M18-LIU NSNBC01 Inductive Proximity Sensor

Turck BI5-M18-LIU is an analog inductive proximity sensor built for contactless metal-target measurement in industrial automation. The LIU-series device provides a linear analog output (0-10 VDC or 0-20 mA) proportional to target distance, with an operating voltage of 15-30 VDC and a no-load current around 8 mA, enabling continuous position feedback rather than simple on/off switching. It features an M18 x 1 threaded barrel in chrome-plated brass, 64 mm long, IP67 protection, and a 2 m integral cable designed for flush mounting in harsh environments, with a rated sensing distance of 5 mm and a measuring range of 2 to 4 mm. Common applications include material handling, conveyors, machine tools, and packaging lines where analog position, displacement, or level sensing is required; it also offers special features like simultaneous current and voltage outputs, reverse polarity protection, short-circuit protection, and a linear output tied to target distance. Common replacements: Turck BI5-M18E-LIU-H1141; Turck BI8-M18-LIU; Turck BI8-M18E-LIU-H1141.
