Abstract
A field device has a housing providing EMC-protection. The housing includes a conductive housing core, which is surrounded on all sides by a non-conductive housing jacket secured thereon by force-interlocking, e.g. frictional interlocking, or by material bonding. At least one electrically conductive barrier is placed on and connected with an electrically conducting region of the housing core and divides the interior of the housing into at least two chambers with different degrees of EMC-protection. The barrier contains a passageway, with which at least a first electronic circuit and a second electronic circuit, which are located in different chambers, are contacted with one another. The circuits are contacted by spring contacts against regions of the housing core, which are led through the housing jacket into the interior, wherein transitions to a sensor—or lid in the housing by means of screw thread—and/or wiping contacts are so arranged that these kinds of components are electrically connected with the housing core and wherein seals of the transitions protect against environmental influences.
