Secondary Encoders: move articulated robots very precisely

Modular optical angle encoders from HEIDENHAIN or the WMRA inductive angle encoder system from AMO can significantly improve the absolute position accuracy of robots. Mounted downstream from the gear system, these secondary encoders measure the actual position of each robot joint. Thanks to their modular design with a scale drum or measuring ring and a separate scanning unit, they are ideal for large shaft diameters and also for difficult installation situations.
