Abstract
A load sensor includes a housing and a magnet carrier axially movable within the housing. A first and a second magnet are coupled to the magnet carrier in an axially spaced apart arrangement and oriented to provide repelling magnetic fields. The magnet carrier and the first and second magnets are axially movable relative to the magnetic field sensor, and the magnetic field sensor is configured to provide an output that is indicative of the position of the magnetic filed sensor relative to the first and second magnets.
