Abstract:
An electronic position encoder includes a scale comprising a pattern track having a track width dimension along a y-axis direction that is perpendicular to an x-axis measuring axis direction, a detector, and a signal processing configuration. The detector includes a field generating coil configuration fixed on a multi-layer printed circuit board (PCB), including a field generating coil portion that surrounds an interior area aligned with the pattern track and includes first and second elongated portions having a trace width along the y-axis direction, which is at least 0.1 times a y-axis width of the interior area. The detector includes conductive receiver loops arranged along the x-axis direction and fixed on the PCB. The first and second elongated portions are fabricated using at least an interior copper layer of the PCB, and the conductive receiver loops are fabricated using at least one copper layer that is closer than the interior copper layer to a front surface of the detector that faces the scale pattern.

Claim (Index 13):
The electronic position encoder of  claim 11 , wherein:\n the first and second pattern tracks each include the same type of signal modulating elements that are arranged according to a same spatial period or wavelength W along the x-axis direction in the first and second pattern tracks, wherein the signal modulating elements in the second pattern track are offset along the measuring axis direction by a nominal scale track offset of approximately W/2 relative to the signal modulating elements in the first pattern track; the field generating coil configuration is configured to generate the first-track changing magnetic flux with a first polarity in the first interior area, and generate the second-track changing magnetic flux with a second polarity that is the same as the first polarity in the second interior area; and at least a majority of the conductive receiver loops each span the first and second interior areas along the y-axis direction and include a cross over or twisting of their conductive traces to provide opposite sensing loop polarities in the first and second interior areas.
