Autonics PR18-8DN Inductive Proximity Sensor PR188DN

Description:

The Autonics PR18‑8DN inductive proximity sensor is used in industrial automation systems to detect the presence of metal objects without physical contact. Commonly installed in packaging lines, conveyors, automated machinery, and assembly systems for position sensing and object detection. Maintenance teams and system integrators use this sensor for system upgrades, machine diagnostics, and replacement of worn or failed proximity switches.

Applications:

The Autonics PR18‑8DN sensor is widely used in automation environments requiring reliable non‑contact metal detection. It is commonly found in material handling systems, conveyor controls, robotic cells, CNC machines, and packaging equipment where fast and repeatable sensing of metallic targets is critical for part counting, safety functions, and process sequencing.
