Turck NI4-G12-AZ31X Inductive Proximity Sensor

The TURCK NI4-G12-AZ31X Inductive Sensor is a compact, M12×1 threaded inductive proximity sensor designed for non-contact metal detection and machine-position sensing in automation lines. Its AC/DC two-wire design allows direct integration into relay logic and legacy controls without a separate DC supply, operating on 20-250 VAC or 10-300 VDC and providing a normally open (NO), 2-wire output rated at 3–100 mA with a 4 mm sensing distance. Built for industrial environments, it uses a chrome-plated brass housing with a PA12-GF30 plastic active face, a non-flush (non-embeddable) mounting style, and an IP67 enclosure, operating from -25°C to +70°C and switching at up to 20 Hz with a cable connection. Common applications include conveyors, packaging and assembly equipment, machine tools, automotive lines, and other manufacturing processes requiring end-of-travel sensing or part presence verification, making it a reliable replacement or retrofit option within TURCK NI4-G12-AZ31X deployments.
