Abstract
A non-contacting linear position sensor having bipolar tapered magnets. A pair of magnets are positioned adjacent each other and attached to a movable object. Each magnet has a central portion that is thinner than both ends of the magnets. A pair of pole pieces has ends that are arranged spaced apart in parallel relationship about the central portion. The other ends of the pole pieces are located spaced apart with a magnetic flux sensor located between. The magnetic flux sensor senses a variable magnetic field representative of the position of the attached movable object as the magnets move. The magnets have opposite polarities on either sides of the central portion.
