1. A rotary encoder having integrated therein a detector device comprising at least one measurement sensor by which, during operation, a measurement signal can be generated that is representative of the angular position and/or velocity of an object which is connectable to the rotary encoder, at least one rotary bearing, and at least one material measure which is arranged rotatable relative to the measurement sensor in the measurement field thereof by means of the rotary bearing, and a monitoring device which is connected to the measurement sensor such that data are transmitted, wherein the monitoring device comprises a counter which can permanently store a value which is representative of the state of wear of the rotary bearing and is formed from the information contained in the measurement signal on the angular position and/or velocity.
