Turck Ni25-G47-AZ3X Inductive Proximity Sensor

Description:

The TURCK NI25-G47-AZ3X Proximity Switch Sensor is used in industrial automation and machine control systems to provide non-contact detection of metallic objects using 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 NI25-G47-AZ3X is designed for industrial proximity sensing applications where dependable metal target detection is required without physical contact while operating directly from AC or DC control circuits. 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. Its large threaded housing and extended sensing distance provide increased installation flexibility for demanding industrial environments.
