Abstract
An inductive encoder system includes a scale including a periodic scale pattern, and a detector portion configured to move along a measuring axis direction relative to the periodic scale pattern. The detector portion includes a field generating portion configured to generate a changing magnetic flux, and a sensing portion comprising one or more sets of sensing elements and configured to provide detector signals which respond to a local effect on the changing magnetic flux provided by the periodic scale pattern, wherein each set of sensing elements is coupled to a set of sensor vias. The detector portion further includes a plurality of shield structures SST, wherein each shield structure SST is located proximate to a set of sensor vias and comprises a plurality of shield vias, and in each shield structure one or more shield loops are formed by the plurality of shield vias as coupled together by conductor portions.
