Abstract: A solenoid actuator includes a housing assembly, a bobbin assembly, a coil, an armature, and an anti-rotation structure. The bobbin assembly is disposed at least partially within the housing assembly and includes a return pole and a yoke. The yoke has an inner surface that defines an armature cavity. The coil is disposed within the housing assembly and is wound around at least a portion of the bobbin assembly. The armature is disposed within the armature cavity and is axially movable relative to the yoke. The anti-rotation structure is disposed within the housing assembly and engages at least a portion of the armature. The armature and the anti-rotation structure each have at least one feature formed thereon that mate with each other and thereby prevent rotation of the armature.
