Modular field device

A field device, comprising:

• a housing including a first housing part that forms a first interior, a second housing part that forms a second interior that adjoins the first interior, and a connecting means that mechanically connects the first housing part to the second housing part such that the first housing part and the second housing part are rotatable relative to one another by at least 90° about a common housing axis;
• a first electronics module that is arranged rigidly in the first interior;
• a second electronics module that is arranged in the second interior so as to be rotatable about the housing axis and non-displaceable in relation to the housing axis;
• a transmission means that mechanically connects the second electronics module to the first electronics module and/or to the first housing part so that the transmission means transmits a rotation about the housing axis of the first housing part relative to the second housing part to the second electronics module;
• and
• an electrical plug contact that is arranged so as to be freely rotatable about the housing axis between the second housing part and a side of the second electronics module facing away from the first electronics module.
