Linear encoders for long-range mobility
During the machining and assembly of very large aerospace or energy-sector components, industrial robots need to access all operating positions along the length of a fuselage or large composite part. Position measurement provided by a linear encoder can compensate for thermal error and other effects on the feed mechanism that cannot be measured by a rotary encoder and the ball screw pitch. For high-accuracy robot positioning with a linear motor, ideal solutions are the up to 30 m long linear encoders from HEIDENHAIN, modular unlimited-length scale tape solutions from AMO, or customized linear encoders from RSF.
