The wrap-around encoder solution

RKL encoder scales are a family of robust, narrow, thin and highly flexible scales that can be wrapped around drums, shafts or arcs with radii down to 26 mm, and provide best accuracy on a partial arc when compared to other types of tape scale. Partial arc encoders are found in a wide range of applications including wire bonders for back-end semiconductor manufacturing and synchrotron mirror benders for beamline X-ray experiments. They are usually specified when only small angular movements are required and also enable arc measurement around larger radii of curvature than is possible with conventional rotary (angle) scales.
