Claim 29:
30. A magnetic sensor module, comprising:
a toothed wheel configured to rotate about a rotation axis that extends in an axial direction;
a front-bias magnet magnetized with a magnetization direction that extends along a symmetry axis of the front-bias magnet that is orthogonal to the rotation axis;
a magnetic sensor comprising a first sensor element arranged on an extension of the symmetry axis that coincides with the magnetization direction of the front-bias magnet, wherein the first sensor element is sensitive to a magnetic field of the front-bias magnet that is aligned with the symmetry axis, and wherein a rotation of the toothed wheel causes the magnetic field to oscillate between a first extremum value and a second extremum value at a location of the first sensor element; and
a molded package that encapsulates the front-bias magnet and the magnetic sensor, wherein the molded package comprises a package notch formed between the front-bias magnet and the magnetic sensor along the extension of the symmetry axis, wherein the package notch is formed to enable a plurality of teeth of the toothed wheel to pass through the package notch during a rotation of the toothed wheel.
