Turck NI20U-G30-ADZ30X2-B3131 Proximity Sensor

Description:

The TURCK NI20U-G30-ADZ30X2-B3131 Inductive Proximity Sensor is used in industrial automation and machine control systems to provide non-contact detection of metallic objects using UPROX Factor 1 sensing technology and a universal 2-wire AC/DC output design. Commonly installed in conveyor systems, packaging machinery, material handling equipment, process automation systems, and production machinery requiring reliable metal detection with AC or DC powered control circuits. Maintenance teams and system integrators use this part for sensor replacement, machine retrofits, automation upgrades, and OEM equipment repairs.

Applications:

The TURCK NI20U-G30-ADZ30X2-B3131 is designed for industrial proximity sensing applications where dependable detection of steel, aluminum, brass, and stainless steel targets is required without physical contact. It is frequently used in bottling equipment, transfer conveyors, machine tools, pallet handling systems, and packaging machinery where accurate object detection improves machine reliability and reduces mechanical wear. The UPROX technology provides equal sensing distance for all metals while offering resistance to magnetic fields and harsh industrial environments.
