Abstract
An elevator positioning system includes an optical tape, optical tape clips, and a sensor. The optical tape clips are resiliently biased and mount to various structures including mounting bracket that attach to elevator guide rails or other framework within the hoistway. A connecting member of the optical tape clips is configured to be disposed between a sensor and optical tape such that the sensor detects an interruption in the optical tape and can send signals to an elevator controller in response to detecting these interruptions. The position of the optical tape clips is such that the elevator car can be controlled to align evenly with the landings associated with the hoistway.
