ABSTRACT:
A rotary position sensor for sensing the angular position of a pivotally mounted device, such as a throttle valve. The rotary position sensor includes a generally circular magnet with a central aperture. A magnetic sensing element, such as a Hall effect integrated circuit (IC) is disposed within the aperture to reduce the overall size of the sensor. In order to improve performance of the sensor, one or more flux concentrators are disposed adjacent the magnetic sensing element within the central aperture of the magnet, while keeping the overall size of the sensor to a minimum to enable the sensor to be utilized in applications where space requirements are generally critical, such as automotive applications.
