The sensor is mounted on a plate that has a keyed connection to the housing. The rotary encoder is arranged between the housing and the plate. The rotary encoder has a shaft support or is connected to a shaft support, with the shaft support arranged on the same side of the rotary encoder as the material measure and the plate having a recess for the shaft support.
