Summary:A field device having a non-metallic housing and electrical components accommodated in a Faraday cage includes an electrically conductive pin to ground the cage. For this purpose, the housing includes a bushing into which the pin can be inserted along an axis. The housing and the cup are arranged relative to each other such that the receiving region of the cup for the end of the pin is aligned with the bushing along the insertion axis. The field device includes an electrically conductive spring that resiliently encloses the end of the pin in the receiving region radially with respect to the insertion axis such that the pin is electrically contacted with the cup. A particular advantage of this design is that the pin cannot tilt during insertion despite any component tolerances of the cup or of the housing.
