Abstract
An electronic position encoder includes a scale comprising first and second pattern tracks including respective signal modulating scale patterns, a detector and a signal processing configuration. The detector includes first-track and second-track field generating coil portions that surround first and second interior areas aligned with the first pattern track and second pattern track, respectively. The first-track and second-track field generating coil portions each include first and second elongated portions extending along the measuring axis direction, connected to end portions extending along a y-axis direction transverse to the measuring axis. The detector includes sensing elements that span across the first and second interior areas along the y-axis direction. A nominal y-axis trace width dimension of the elongated portions is at least 0.1 times a y-axis width of the first and/or second interior areas. In various implementations, a shielded end section may be used to connect the elongated portions.
