Abstract
An actuator includes an electrically conductive coil defining a longitudinal axis (L) and having a plurality of winding turns. A magnet is spaced from the winding turns in radial direction. A first conductive element has a mid region covering the coil on a side thereof facing away from the magnet. A second conductive element has a mid region covering the magnet on a side thereof facing away from the winding turns of the coil. The first conductive element projects beyond the coil in axial direction and the second conductive element projects beyond the magnet also in axial direction. The first and second conductive elements have respective collar-shaped projections whereat the first and second conductive elements project beyond the coil and the magnet, respectively. At least one of the first and second conductive elements is made of soft-magnetic powder composite material.
