Abstract
Position sensors to inductively sense a position of a target relative to a number of sensor coils are described. In one embodiment, the target comprises first, second, and third portions positioned on either side of an axis of rotation, such that lateral misalignment between the target and the sensors is compensated between the interaction of the different portions and the sensor coils. In another embodiment, the target comprises first and second portions that are separated along the measurement path such that in a first range of relative positions, the first portion is adjacent to the sensor coils and in a second range of relative positions, the second portion is adjacent to the sensor coils. The first and second portions are asymmetrically arranged relative to the sensor coils such that when each portion is adjacent the same portion of the sensor coils, different signals are induced in the sensor coils.
