Patent ID: 7308765

Claim:
An angle-measuring arrangement, comprising a base body; a code disk, which is rotatable relative to said 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 said angle-measuring arrangement directly from a further stationary body that is external to said angle-measuring arrangement, wherein said contact area: is arranged to be stationary with respect to said base body; has an identical electrical potential at every point of said contact area; and is configured in such a way that a first point is defined by polar coordinates R and α 1 , and a second point by polar coordinates R and α 2 , wherein said first and second points are located on said contact area, and R is a distance of an identical size of said first and second points from said axis A, and α 1 and α 2 represent different angles as measured from an axis X that lies within a plane that contains said first and second points and intersects said axis A, wherein said contact area enables said angle-measuring arrangement to be mounted to said further stationary body at different angular positions while still allowing said electrical current or electrical signals to be conducted into said angle-measuring arrangement directly from contact elements of said further stationary body that directly contact each of said first and second points of said contact area.
