Abstract: A housing module includes a housing including a housing wall, a first housing chamber and a second housing chamber separated by a partition wall, wherein: the partition wall has a through-opening for an electrical feedthrough for connecting measurement/operating electronics to interface electronics; the feedthrough satisfying requirements of an Ex-d standard; the feedthrough having an electrically insulating carrier body and a plurality of electrically conductive connecting devices for providing the electrical connection, which connecting devices extend through holes in the carrier body; the holes each having a first dimension along a hole axis and each having an inner diameter; the connecting devices each having an outer diameter; the carrier body being inserted into the through-opening from a side of the partition wall facing the first housing chamber, and forming a flame arrestor according to the Ex-d standard.

Abstract: Disclosed is an electronic device comprising: a radio module designed to exchange information; an interface device designed to receive a SIM card, the interface device having a data interface, a clock interface, a reset interface and a supply interface designed to supply power to the SIM card; and a circuit board, on which the radio module and the interface device are arranged and electrically connected to one another; characterised in that the radio module has a voltage specification circuit and an associated voltage output, which voltage specification circuit is designed to specify an operating voltage for the SIM card, a fourth electrical connection having a decoupling circuit with power-limited output to the supply interface, which decoupling circuit is designed to decouple the voltage specification and energy supply of the SIM card from one another.
