Abstract
The effective operating range of an actuator magnet on a position detecting array of solid state hall effect devices improved by the use of flux concentrating elements which direct the flux along the array of sensing devices. The flux concentrating elements comprise a series of rods each avowing a magnetic permeability substantially greater than that of free space, such as soft ferrite, which are placed alignment with and between each sensing device in the array.
