Abstract:
A magnetic sensor device for determining a rotation speed, a direction of rotation, and/or a rotation angle of a magnetic component rotating about a rotation axis is provided. The magnetic sensor device includes a magnet being rotationally symmetrical with respect to a symmetry axis, wherein a recess is formed within the magnet along the symmetry axis. Further, the magnetic sensor device includes a first magnetic sensor element arranged within the recess and on the symmetry axis, and a second magnetic sensor element arranged within the recess and on the symmetry axis. The magnetic sensor device additionally includes an integrated circuit arranged within the recess and configured to determine the rotation speed, the direction of rotation, and/or the rotation angle of the magnetic component based on a first output signal of the first magnetic sensor element and a second output signal of the second magnetic sensor element.
