Abstract
An accurate position sensor that operates over a long range is provided. The position sensor can include a first sensor coil having a first number of periods over a range of motion of a target; and a second sensor coil having a second number of periods over the range, wherein the first number of periods is different from the second number of periods, and wherein the first sensor coil and the second sensor coil are arranged with respect to one another such that the target engages both of them simultaneously. In some embodiments, the first number of periods is one and the second number of periods is greater than one. In some embodiments, the first number of periods is greater than one and the second number of periods is greater than the first number of periods.
