Their MAGNODUR measuring standard and the magnetoresistive scanning principle make them particularly tolerant to contamination. Typical applications include machines and equipment with large hollow shaft diameters in environments with large amounts of airborne particles and liquids, for example p on the spindles p of lathes or milling machines, for reduced accuracy requirements.

Speed range: 3000 upto 19000 rpm (depending on diam) HEIDENHAIN ITALIANA S.r.l Arienti Oscar June 2011 ERM 2410 application key factors: • Since interpolation already takes place in the scanning head, there is no danger of possible noise interference during transmission of the analog signals to the subsequent electronics, which would influence the accuracy •The EnDat 2.2 interface (ordering designation EnDat 22) enables automatic commissioning g of the AK ERM 2410,, since all information necessaryy for the subsequent q electronics is stored in the encoder. The 14-bit interpolation achieves resolutions that make ideal control conditions possible in the applications typical for magnetic built-in encoders. •During formation of the position value, monitoring functions that lead to a high system reliability are active. The alarms supported also make rapid diagnosis possible should an error occur. The Cyclic Redundancy Check at the end of the position value continues to ensure high reliability of the transmission. •The Th distance-coded di t d d reference f marks k off the th ERM 200C scanning i h heads d simplify i lif th the reference runs, and the absolute reference is quickly established.
