Abstract

The invention relates to a measuring system for contactless detection of a rotational angle, having a first body on which at least one magnet is disposed and having at least one magnetic-field-sensitive element, supported by a second body, for generating a measurement signal, the first body and the second body being rotatable counter to one another about an axis of rotation, and the magnet having a blind-borelike recess. The invention provides that the at least one magnetic-sensitive element protrudes at least partway into the recess.
