Abstract
An apparatus for detecting a geometric relation includes a device having a magnetic field source and a configuration being formed of a multiplicity of Hall elements. A magnetic induction is dependent on the relative geometric configuration between the Hall element configuration and an object having a geometric position which is to be detected. The Hall elements are disposed at a given distance from one another along a given line. An interpolation circuit interpolates the analog output signals of at least two Hall elements.
