Turck Ni20-CK40-AP6X2-H1141 Inductive Proximity Sensor

Description:

The TURCK NI20-CK40-AP6X2-H1141 Inductive 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 PNP normally open output configuration. Commonly installed in conveyor systems, automotive assembly lines, material handling equipment, transfer systems, and heavy industrial machinery requiring long-range metal detection and reliable position feedback. Maintenance teams and system integrators use this part for sensor replacement, machine retrofits, automation upgrades, and OEM equipment repairs.

Applications:

The TURCK NI20-CK40-AP6X2-H1141 is designed for demanding industrial proximity sensing applications where long sensing distances and reliable operation in harsh environments are required. It is frequently used in pallet conveyors, steel processing equipment, packaging machinery, robotic cells, and automated production lines where conventional barrel sensors cannot provide adequate sensing range. The UPROX technology provides consistent detection performance across all metal types while offering resistance to magnetic fields and harsh industrial conditions.
