Abstract: A non-contacting type sensor and method for sensing angular position are provided for sensing the angular position of a body such as a throttle valve. The sensor includes a stator assembly and a rotor assembly adapted to be coupled to the body for rotation relative to the stator assembly. The rotor assembly includes a closed-loop magnetic flux concentrator which defines a controlled electromagnetic cavity and generating means for generating a first magnetic field within the cavity. The stator assembly includes a semiconductor device disposed within the cavity and having an electrical property which is a function of the orientation and strength of a resultant magnetic field. The stator assembly further includes a coil wound about the device for producing a second magnetic field which substantially cancels the effects of the first magnetic field on the device so as to obtain the resultant magnetic field.
