An electromagnetic actuator for a hydraulic directional control valve is provided. The electromagnetic actuator is used for adjusting a hydraulic directional control valve, for example, for the variable adjustment of the control times of an internal combustion engine. The electromagnetic actuator includes a housing (08) with which the electromagnetic actuator is mounted opposite the hydraulic directional control valve. The electromagnetic actuator further includes a coil (01) that is arranged in a coil body (03). The electromagnetic field that can be generated with the coil (01) acts on an armature (09) that is arranged in the electromagnetic actuator so that it can move axially. In order to prevent that the hydraulic medium of the hydraulic directional control valve leaks from reaching the electromagnetic actuator, the actuator includes a seal (13; 24) between the coil body (03) and the housing (08). The coil body has a holder (26, 28) for holding the seal (24). The holder (26, 28) guarantees the holding of the seal (24) in the coil body at least during the assembly of the electromagnetic actuator, so that when the coil body is introduced into the housing (08), the seal (24) remains at the provided location, even if it is not yet fixed by a pressure against the housing (08).
