ABSTRACT:
A solenoid actuator having a slider element with a permanent magnet is provided. When the electromagnet is activated, the electromagnet repels the permanent magnet, moving the permanent magnet of the slider toward a second position under the influence of a mass of ferro-magnetic material located adjacent the second position. In a preferred embodiment, the poles of the slider permanent magnet are co-axially aligned with the coil and core of the electromagnet. In an alternative embodiment, the mass of ferromagnetic material may be eliminated.
