ABSTRACT:
A monolithic body having angle scaling is rotatable about an axis to measure the rotational position of a machine part. The body has a first annular region which has a flange-type configuration for connection to the machine part, and a second annular region on which the angle scaling is arranged, as well as a crosspiece region. The crosspiece region is arranged between the first annular region and the second annular region. The crosspiece region has a geometrical extension in the direction of the axis which is at least three times smaller than the greatest geometrical extension of the second annular region in the direction of the axis (Z).
