Abstract:
A rotary position sensor (102) may include a sensor housing (202) defining an interior cavity. A first rotor (206) may be positioned and rotatable within the interior cavity, the first rotor (206) including a first magnet (326). Furthermore, the rotary position sensor (102) may include a second rotor (208) positioned and rotatable within the interior cavity, the second rotor (208) including a second magnet (328). The first magnet (326) may include a first shielding member (342) associated with a surface of the first magnet (326), and the second magnet (328) may include a second shielding member (344) associated with a surface of the second magnet (328). The first shielding member (342) may face the second shielding member (344).
