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: A field device comprising a protection circuit between a communication interface and a signal processing unit. A communication interface is preferably an Ethernet connection of the field device, wherein between the communication interface and the signal processing unit a first system is provided, which serves for electrical current limiting, wherein between the first system for electrical current limiting and the signal processing unit a means is provided, which serves for voltage limiting, and wherein between the means for voltage limiting and the signal processing unit a second system is provided, which serves for energy limiting.
