Turck NI20-CP40-VP4X2-B1141 Inductive Proximity Sensor

Description:

The TURCK NI20-CP40-VP4X2-B1141 Inductive Sensor is used in industrial automation and machine control systems to provide non-contact detection of metallic objects using a complementary PNP output configuration and extended sensing distance technology. 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-CP40-VP4X2-B1141 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 CP40 rectangular housing allows flexible mounting while UPROX technology provides consistent detection performance across all metal types and resistance to magnetic fields and industrial interference.
