摘要
An inductive position sensor including at least one transmit coil, an absolute position receive coil pair, a high-resolution position receive coil pair and a conductive moving target, the absolute position receive coil pair and the high-resolution receive coil pair together define a measurement area of the inductive position sensor and the moving target can move in this measurement area, the absolute position coil pair has a first sine receive coil and a first cosine receive coil, both having one period over the measurement area of the inductive position sensor, the high-resolution position receive coil pair has a second sine receive coil and a second cosine receive coil, both having at least two periods over the measurement area of the inductive position sensor, the absolute position receive coil pair and the high-resolution position receive coil pair are arranged in the same area of a printed-circuit board of the inductive position sensor.
