PEPPERL FUCHS 11620S NJ5-18GK-A2 PROXIMITY SWITCH NJ518GKA2

Description:

The Pepperl+Fuchs 11620S NJ5‑18GK‑A2 inductive proximity switch is used in industrial automation systems to detect the presence of metal objects without physical contact and provide reliable switching signals. Commonly installed in conveyor systems, packaging equipment, assembly machines, and robotic cells. Maintenance teams and system integrators use this sensor for system reliability, upgrades, and replacement of worn or failed proximity switches.

Applications:

The Pepperl+Fuchs NJ5‑18GK‑A2 sensor is widely used in automation environments requiring non‑contact metal detection and position feedback. It is commonly found in material handling systems, packaging lines, pick‑and‑place machines, CNC equipment, and safety interlock applications where accurate and repeatable detection of metallic targets is critical for process control and production efficiency.
