ABSTRACT:
A rotary encoder includes a first component group and a second component group, the two component groups being rotatably arranged relative to each other in a measuring operation. The first component group has a detector system, a housing part having at least one wedge-shaped element, and a clamping ring having at least one cam. The second component group includes a code disk and a shaft. The housing part is arranged radially outside of the shaft, and a force having a radial directional component oriented toward the axis is applicable on the at least one wedge-shaped element via the at least one cam by a turning motion of the clamping ring relative to the housing part such that the shaft is able to be clamped on the housing part outside of the measuring operation.
