Abstract
A magnetic system for an electromagnetic relay including a core having a winding carrier section and at least two pole sections adjoining the winding carrier section and each of the pole sections has a free end. An armature is positioned under the pole sections and forms at least one working air gap with the free ends of the pole sections. Three inner insulation layers surround the core with the exception of the free ends of the pole sections adjacent the armature. At least one of the three inner insulation layers forms a coil body having two coil body flanges. A winding is positioned between the two coil body flanges. A fourth insulation layer surrounds the three inner insulation layers and the winding. A fifth and a sixth insulation layer is arranged such that the winding is surrounded by three insulation layers at a section facing toward the armature.
