The robust ERM modular magnetic encoders are especially suited for use in production machines. Their large available inside diameters, their small dimensions and the compact design predestine them for C axis on lathes / Rotary and tilting tables. For years, the ERMs have been the preferred encoders for C axes on lathes. Besides their high resistance to contamination, the large inside diameters are also important to allow bar material to be machined without limitations. Because of this design arrangement, the graduation of the ERM is usually on a much larger diameter than the workpiece. Position errors of the encoder therefore affect workpiece accuracy to a correspondingly reduced degree.
