Abstract: An electromagnetic actuator includes a housing and a bobbin positioned within the housing and secured relative thereto so as to be centered therein, the bobbin comprising a bobbin formed of a non-magnetic material. The electromagnetic actuator also includes a coil wound about the bobbin and a magnetic circuit comprising a plurality of actuator components positioned within the housing and on or adjacent to the bobbin. The actuator components include a permanent magnet that induces a magnetic flux flow through the magnetic circuit so as to generate a magnetic force, and an armature selectively movable within an opening formed through the bobbin responsive to the magnetic force and to current selectively provided to the coil. The bobbin locates and centers the components of the magnetic circuit about the central axis and provides a bearing surface for the armature as it moves within the opening formed through the bobbin.
