Abstract
A rotary actuator comprises a housing with an output shaft extending from the housing. There is a magnet disposed on the output shaft and the output shaft is coupled to an actuator arm. A motor rotates the output shaft. A position sensor mounted on a circuit board determines the position of the output shaft based on the position of the magnet. A position of the actuator arm may be determined based on the rotating position of the output shaft.
