3D Hall

Based on a proprietary ASIC, 3D Hall technology is used in position and current sensing.

In sensors that leverage the Hall effect, the actual measurement signal results from the deflection of electrons in a Hall plate under the influence of magnetic fields. Based on this fundamental effect, the 3D Hall ASIC developed by AST operates in 3 spatial directions and can thus also detect magnetic field vectors in three-dimensional space. The Hall sensor’s high level of sensitivity in combination with the integrated evaluation electronics makes it possible to detect magnetic fields down to the sub-µTesla range. 3D Hall technology is deployed at AST for both contactless current measurement and position sensing. This enables a position to be measured in three dimensions.
