Rotation angle sensor having two sensor signals and operating method

A sensor arrangement for determining a rotation angle of a magnet about an axis of rotation relative to a base carrier, the sensor arrangement comprising:

• the base carrier;
• the magnet configured to rotate relative to the base carrier about the axis of rotation to generate a magnetic measuring field;
• a first sensor positionally fixed relative to the base carrier and configured to capture a first tangential component and a first axial component of the measuring field with respect to the axis of rotation, wherein the first sensor is arranged at a first circumferential position with respect to the axis of rotation and at a first radial distance from the axis of rotation;
• at least one second sensor configured to capture a second tangential component and a second axial component of the measuring field with respect to the axis of rotation and which is arranged at a second circumferential position with respect to the axis of rotation and at a second radial distance from the axis of rotation;
• and
• an evaluation unit configured to determine the rotation angle from at least three of the first tangential component, the second tangential component, the first axial component, or the second axial component by means of an arc tangent function.
