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


Inductive distance sensors (AlphaProx) operate on the same measuring principle as inductive proximity switches. They generate a high-frequency electromagnetic field close to the sensing face. The presence of any metal object in this area will change the field according to distance, object material and size. The sensor will detect such change and convert it into proportional output signals. Standard AlphaProx sensors use purely analog conversion. As a result, they ensure high measurement speeds, excellent repeatability, low noise and high resolution.
