ABSTRACT:
Electromagnetic relay having a sealed housing. The relay has a housing with a cap and a bottom part. The region of the bottom part under the coil winding has a bottom section that is set back in height, as a result whereof the space between the coil flanges and under the winding also becomes accessible from the outside when the relay is attached to a printed circuit board. The bottom part may potentially have cup-shaped bellied portions as an envelope for the coil flanges. The joining seam between the at least partially height-offset bottom part and the shortened cap is upwardly displaced in this way from the lower terminating plane at least to the lower apex of the coil winding. The relay housing can be sealed with casting resin in this joining plane, whereby clearances in the lower terminating plane of the housing as well as in the height-offset joining plane can be sealed in common using a capillary system. Additional components can be arranged on the printed circuit board in the free space under the winding. Moreover, the space under the relay is more easily accessible for cleaning the printed circuit board.
