Distance-measuring, inductive sensors offer many application possibilities. A basic distinction is made between direct distance measurements/position feedback and indirect, specific measurements.

Inductive distance sensors (AlphaProx) are based on the same measuring principle as inductive proximity switches. They generate a high-frequency electromagnetic field near the sensing face. A metal object penetrating this area will change the field depending on object distance, material and size. The change is detected by the sensor and converted into a proportional output signal. Standard AlphaProx sensors operate all-analog which makes them capable of high measuring speed together with excellent repeat accuracy, low readout noise and high resolution.
