ABSTRACT:
The present invention describes a release mechanism (1) for releasing magnetically releasable anti-theft devices consisting of a multiplicity of permanent magnets in the form of a Halbach array, which are disposed on a plane. While the highly magnetised top side (10) of the release mechanism (1) is covered by the cover plate (6) on the release side, a base plate (5) used for mounting or support is located on the underside (11) of the release mechanism (1). The permanent magnets encompass a continuous, self-contained frame magnet (2), which is magnetised in an axial direction and has a first recess. Inserted in this first recess is a segmented magnet (3), wherein the individual segments are magnetised perpendicularly to the magnetization direction of the frame magnet (2) and a second recess is left open, in which an axially magnetised magnetic core (4) is inserted.
