Abstract
An optoelectronic apparatus for transmission of an electrical signal via, galvanically isolated by means of a one-piece, translucent, plastic body, an input current circuit. At least one optical transmission element, and an output current circuit, having at least one optical receiving element, wherein the optical transmission element has a principle transmission axis and the optical receiving element a principle receiving axis, which are oriented so as to concide with a shared optical axis. The plastic body has two cavities separated via a partition for accommodating, respectively, the optical transmission element and the optical receiving element, wherein the transmitting element and/or the receiving element are/is placed through the openings so far into the cavities of the plastic body, that, following a case of overvoltage on the transmitting element and/or the receiving element, an insulating air distance and creep path according to an insulation coordination is still present along outer surfaces of the plastic body.
