Abstract
An electromagnetic positioning device includes an armature member for actuating a positioning partner and movable in an armature space relative to a stationary core (). The armature member conducts magnetic flux upon energization of a stationary coil (). The coil has a coil support with a winding and at least one external contactable connector () embedded at least in sections in the core and/or surrounded by the core. The core has an end surface (), which is planar at least in sections, for interacting with the armature member. The core and the coil are embedded in and/or surrounded by a one-piece pot-like and/or cup-like housing () made of a material suitable for deep-drawing in such a manner that the core rests on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the armature space.
