Abstract
A rotary encoder includes a housing and a shaft, which has an axis. A graduated disk is fixed in place on the shaft in torsionally fixed manner. The shaft is adapted for the positionally accurate attachment to a first machine part. Furthermore, a scanning device for scanning the graduated disk is fixed in place on the housing, the housing being arranged such that an outer surface forms a positionally accurate rigid stop on a second machine part in the radial direction. The housing includes a housing body and a cover, the housing body and the cover being connected to each other by press-fitting. The housing has a mechanically flexible element which is deformed as a result of the press-fitting.
