Abstract
The invention proposes an electric linear drive unit with an electric linear motor that is arranged in or on a basic housing. A sensor device arranged in or on the basic housing serves for determining at least one position of a driving element that is driven by the linear motor. Electric lines are routed from a coil system of the linear motor and from the sensor device to a common connecting point on the basic housing through at least one duct that extends within the basic housing, wherein said electric lines extend through the connecting point to a connector that is arranged at the connecting point and contains connecting means for producing a connection with external lines or cables. The connecting point is sealed by means of an insulating casting- or injection-molding compound at least in the region in which the lines extend from the connecting point.
