Abstract:
A magnetically-based position sensor. The sensor includes a magnet, a first collector, a second collector, and a magnetic sensing element. The magnet has at least two poles, and moves along a path. The first collector has a first end and a second end and is configured to collect a magnetic flux. In addition, the first collector is positioned at an angle relative to an axis running parallel to the path and perpendicular to the magnet. The second collector is configured to collect a magnetic flux, and is positioned at an angle relative to the axis running parallel to the path and perpendicular to the magnet, and parallel to the first collector. The magnetic sensing element is coupled to the first and second collectors. A magnetic flux is collected by the first and second collectors, and varies as the magnet moves along the path such that the magnetic flux collected by the first and second collectors indicates a position of the magnet along the path.
