Abstract
An angle-measuring arrangement that includes a base body, a code disk, which is rotatable relative to the base body around an axis A and a contact area, which is laid out in such a way that electrical current or electrical signals can be conducted into the angle-measuring arrangement from a further stationary body. The contact area is arranged to be stationary with respect to the base body and has an identical electrical potential at every point of the contact area. The contact area is also configured in such a way that a first point is defined by polar coordinates R and α, and a second point by polar coordinates R and α, wherein the first and second points are located on the contact area, and R is a distance of an identical size of the first and second points from the axis A, and αand αrepresent different angles.
