1. An electromagnetic positioning device (20) comprising at least two actuator units (1a, 1b) arranged adjacent to one another in a housing (10), the actuator units (1a, 1b) each comprising energizable stationary coil means (2a, 2b), armature means (3a, 3b) mounted so as to be movable in relation to the stationary coil means (2a, 2b), and a plunger (4a, 4b) interacting with the armature means (3a, 3b) and mounted so as to be movable along an axial plunger direction (S1, S2) and having a free end section (5a, 5b) for engaging into a positioning partner,
and the device (20) comprising adjustment means (6) integrated into the housing (10) for changing the arrangement of at least one plunger along a plane (E) perpendicular to the respective plunger direction (S1, S2), wherein the adjustment means (6) are configured in such a manner that they enable a change in the relative arrangement of the plungers (4a, 4b) with respect to each other independent of a relative arrangement of the respective associated armature means (3a, 3b) and/or stationary coil means (2a, 2b).
