Abstract
A position-measuring device includes a graduation carrier which carries a measuring graduation and is non-rotatably connectable to a shaft. A scanner is configured to generate scanning signals by scanning the measuring graduation. Evaluation electronics are configured to process the scanning signals into a digital angle value of the shaft. An interface is configured to communicate with subsequent electronics. The scanner is mountable on a machine part that is supported so as to be movable in an axial direction of the shaft, so that the scanning signals are dependent on a position of the machine part in the axial direction of the shaft, and so that a measure of the position of the machine part in the axial direction of the shaft is determinable from the scanning signals by the evaluation electronics.
