PEPPERLFUCHS NJ5-18GK-WS PROXIMITY SENSOR

Description:

The Pepperl+Fuchs NJ5‑18GK‑WS inductive proximity sensor is used in industrial automation systems to detect the presence of metallic objects without physical contact and provide reliable switching signals. Commonly installed in conveyor systems, packaging machinery, assembly equipment, and robotic cells for position sensing and object detection. Maintenance teams and system integrators use this sensor for machine diagnostics, automation upgrades, and replacement of worn or failed proximity switches.

Applications:

The Pepperl+Fuchs NJ5‑18GK‑WS sensor is widely used in factory automation environments that require dependable non‑contact metal detection. It is commonly found in material handling systems, CNC machines, packaging lines, pick‑and‑place machines, and safety interlock systems where accurate and repeatable sensing of metal targets supports process sequencing, part detection, and equipment control.
