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: A field device of measuring- and automation technology, which field device meets requirements for operation in explosion-endangered environments. Safe operation of the field device in explosion-endangered environments is assured by a pluggable connector coupling for electrical coupling of different field device components. An essential feature of the pluggable connector coupling is a sealing element for spatial and gas-tight sealing of a contact region of contacting elements of the pluggable connector coupling from a free volume remaining in the pluggable connector coupling.

Abstract: An electronics housing comprises a housing basic body having a cavity, especially a single cavity. The housing basic body includes a side wall laterally bordering the cavity, an open end and a rear wall bounding the cavity on an end lying opposite the open end and remote therefrom. Also included is a housing lid releasably connected to the housing basic body on the open end and sealing the housing basic body; and an intermediate floor. The intermediate floor, in the case of the electronics housing of the invention, forms: a gap extending between an inner surface of the side wall of the housing basic body and a lateral surface of the intermediate floor facing the inner surface; and two housing chambers in the cavity of the housing basic body separated from one another by the intermediate floor. A first housing chamber is arranged on a first side of the intermediate floor facing the housing lid and a second housing chamber is arranged on a second side of the intermediate floor facing away from the housing lid.
