Autonics PRD12-4DP Inductive Proximity Sensor

Autonics PRD12-4DP is an inductive proximity sensor with a PNP output. Inductive proximity sensors operate by generating an electromagnetic field and detecting changes in that field when metal targets enter the sensing zone, enabling non-contact detection of metal objects. The PRD12-4DP thus provides reliable metal detection without mechanical wear, suitable for repetitive cycling in automation and production lines. The PNP output configuration delivers a positive-switch signal when a metal target is present, which simplifies wiring to PLC inputs and other control devices that use positive logic. Typical applications include metal-part detection on conveyors, sensing end-of-travel or reference positions in machinery, and serving as a metal-detection input in control networks for automated manufacturing environments where fast, non-contact sensing of metal objects is required.
