Abstract
A sensor assembly for determining a number of rotations of a permanent magnet includes a first sensor. The permanent magnet has an axis of rotation, end surfaces lying in an X-Y plane, a central axis, and exactly two poles. The two poles are disposed in the X-Y plane on mutually opposite sides of the permanent magnet so that the permanent magnet is magnetized diametrically. The first sensor is axially fixed and rotationally displaceable relative to the permanent magnet. The first sensor is disposed at a first distance axially offset from the permanent magnet and at a second distance radially offset from the axis of rotation. The second distance is selected so that a vector sum of a radial flux density and a tangential flux density is not less than a first limit value and does not exceed a second limit value.
