Turck NI20-CP40-FDZ30X2-B1131 Inductive Proximity Sensor

Description:

The TURCK NI20-CP40-FDZ30X2-B1131 Inductive Sensor is used in industrial automation and machine control systems to provide non-contact detection of metallic objects using a universal AC/DC 2-wire output design. Commonly installed in conveyor systems, packaging machinery, material handling equipment, transfer 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 NI20-CP40-FDZ30X2-B1131 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 pallet conveyors, packaging equipment, machine tools, transfer stations, and automated manufacturing systems where long sensing distances improve installation flexibility and machine reliability. The Combi-Prox rectangular housing allows mounting in locations where traditional barrel sensors are impractical while providing excellent visibility of operating status LEDs from multiple angles.
