Elevator systems include an elevator car and a roller guide associated therewith. A roller is supported on a frame of the roller guide and configured to rotate along a guide rail and limit movement of the elevator car in a first direction. A motion state sensing assembly is mounted to the roller guide and configured to measure a motion state of the elevator car. The motion state sensing assembly includes an optical target located on the roller and an optical encoder device and associated a processor arranged to direct optical energy toward the optical target and detect a response thereof. A sensor housing is mounted to the roller guide with the optical encoder device arranged within the housing. A communication assembly is in communication with the processor and an elevator controller for communication therebetween.
