<p>The receptacle (1) has a plunger (6) with radial outer rings (22, 24) that are made from a ferromagnetic material or an electrically conducting non-ferrous metal. The ring (24) extends in an axial direction over an entire region of the plunger cooperating with coils (2, 4). Axial length of the ring (22) of the plunger is selected such that the ring (22) overlaps with axial length of a coil opening (8) of the coil (2) and partially overlaps with an axial length of a coil opening (10) of the coil (4) in the positions of the plunger.</p> |
