Abstract

The invention relates to a sensor arrangement (1) comprising a magnet (2), a magnetic field sensor (3) and a twistable or rotatable rod (4), characterized in that the magnet (2) is arranged below the magnetic field sensor (3) and the twistable or rotatable rod (4) is arranged above the magnetic field sensor (3), wherein the rod (4) comprises a lower surface (6) generating a tilt angle between the surface and the plane of the magnetic field sensor.

Claims

1. Sensor arrangement comprising:

a magnet

a magnetic field sensor and

a twistable or rotatable rod

characterized in that the magnet is arranged on one side of the magnetic field sensor and the twistable or rotatable rod is arranged on the other side of the magnetic field sensor, wherein the rod comprises a lower surface of a magnetically conductive material generating a tilt angle between the surface and the plane of the magnetic field sensor.

2. Sensor arrangement according to claim 1, wherein the sensor arrangement comprises a housing, wherein the lower surface of the rod is arranged within the housing.

3. Sensor arrangement according to claim 1, wherein the housing comprises a recess and at least a part of the rod is arranged in the recess of the housing.

4. Sensor arrangement according to claim 3, wherein the recess is used to center the rod.

5. Sensor arrangement according to claim 3, wherein the recess is used as a bearing between housing and the rod.

6. Sensor arrangement according to claim 1, wherein the sensor arrangement comprises a housing, wherein the lower surface of the rod is arranged outside the housing.
