Abstract
An angular position sensor is provided including a rotatable magnet and at least one magnetically sensitive device. The at least one magnetically sensitive device is preferably a plurality of Hall effect sensors disposed on a circuit board for processing the generated electrical signals. The present invention includes a pair of focusing members designed to transmit and uniformly focus a magnetic field across the magnetically sensitive device, wherein the focusing members are tailored to be substantially planar and provide a uniform magnetic field gradient across the magnetically sensitive device. In a preferred embodiment, the present invention also includes at least one shielding member. The angular position sensor may be adapted for use in a control system for the electronic monitoring and control of the throttle plate position in a motor vehicle.
