Automation field device

An automation field device at least comprising:

• a metal field device housing enclosing an inner chamber;
• a sensor element and/or actuator element, arranged on one side of the field device housing, for setting and/or recording a process variable;
• an electronic circuit that is arranged, at least in part, in the inner chamber of the field device housing and is configured to provide and/or process a sensor and/or actuator signal for and/or from the sensor element and/or actuator element, wherein the electronic circuit furthermore has at least one field contact plug for transmitting data and/or energy, wherein the field contact plug is guided outward through an opening in the field device housing, wherein a custom-fit plug sleeve is placed over the field contact plug and is welded onto the field device housing and wherein the plug sleeve is fastened to a retaining means that is arranged in the inner chamber;
• wherein the retaining means is an electronics cup made of a plastics, which is substantially adapted to match an outer contour of the field device housing and is arranged in the inner chamber, and wherein the electronic circuit is arranged, at least in part, in the electronics cup.
