Abstract
The inductive position sensor includes a scale () with a series of conductive loops spaced out by a pitch T and a cursor () provided with conductors forming each a series of alternating hairpin turns spaced out by a pitch T, the inducing (to) and induced (to) cursor conductors are laid out in two separate interlaced conductor groups, coupling between inducing and induced conductors of the second group taking place only via the scale loops. Such a sensor is simple, robust, accurate, insensitive to external electromagnetic fields and tolerant of misalignment between cursor and scale.
