Magnetic angular position sensor apparatus

摘要

Angular position sensing apparatuses and methods are disclosed. An angular position sensing apparatus can include a rotatable base and two or more magnets located proximate to one another upon the rotatable base. The magnets are generally magnetized parallel and opposite to one another to create a uniform magnetic field thereof. Additionally, a sensor can be located external to the two magnets, such that the sensor comes into contact with the uniform magnetic field to sense a change in angular position associated with the rotatable base.
