Turck NI20-G30-ADZ30X2-B3131 Inductive Proximity Sensor

The TURCK NI20-G30-ADZ30X2-B3131 Inductive Proximity Sensor provides non-contact detection of metallic targets with a 20 mm nominal sensing distance, designed for industrial automation and machine control. It features a chrome-plated brass housing (CuZn) in an M30×1.5 threaded barrel and an active PA12-GF30 plastic face, mounted in non-flush installations. The sensor operates from 20-250 VAC or 10-300 VDC and uses a 2-wire AC/DC output with a normally open switching function, supported by a 1/2"-20 UN male connector (B3131). It offers IP67 protection, a operating temperature range of -25°C to +70°C, and a red LED status indicator, plus short-circuit, reverse polarity, and latching overload protections. Electrical ratings include a maximum AC current of 400 mA and a maximum DC current of 300 mA, with a minimum operating current of 3 mA and a switching frequency of 20 Hz. Commonly used in bottling equipment, transfer conveyors, machine tools, pallet handling systems, and packaging machinery where reliable metal-object detection supports precise machine positioning and automation control.
