Abstract

An internal combustion engine throttle position sensor has a shaped dual magnet structure carried upon a pole piece having a generally "c" shaped cross-section. The magnet and pole piece define a generally circular linear field which is concentric about the axis of rotation of the complete rotor. A Hall effect device is inserted into the open portion or gap between the two magnets and is exposed to a well defined field.
Through the use of selected geometries and particular magnet materials, a precise and yet tolerant magnetic circuit is produced.
