The present disclosure relates to a field device of automation technology, including a housing with an opening for accommodating field device components, wherein the housing has at an edge of the opening a first screw thread, a lid for closing the opening of the housing, wherein the lid has at an edge of the lid a second screw thread, wherein the first and second screw threads are embodied to be complementary to one another, so that the housing after closing with the lid in assembly fulfills all Ex-d requirements, wherein the first and second screw threads are embodied as multi-start threads.

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 sensoror lid in the housing by means of screw threadand/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.

The present disclosure relates to a high-frequency plug connection for high-frequency-based field devices, consisting of plugs and corresponding sockets. The high-frequency plug connection is characterized in that the at least one plug is resiliently enclosed by an enclosure such that this/these plug(s) is/are moveable radially with respect to its/their plugging axis. This has the advantage of reducing the risk of jamming against the enclosure when the plugs are inserted in the corresponding sockets, during fastening of the circuit board substrate on which the sockets are arranged. A modular design of the high-frequency-based field device, and the manufacturability thereof, are simplified as a result.

A display-equipped controller includes a display device, a first junction configured to electrically connect the display device and a main board, a radiator disposed opposite from the display device with respect to the main board, an attaching structure attaching the main board and the radiator to the display device, a support structure disposed between the display device and the main board and configured to detachably support a control board, and a second junction configured to electrically connect the main board and the control board supported by the support structure.

A field device for process automation in industrial or private environments, comprising an electronic circuit for controlling the field device, wherein the electronic circuit includes a first, a second and a third circuit board. The first circuit board is connected to and attached to the second circuit board and/or to the third circuit board by way of an electrical connector, wherein the second circuit board is located above the third circuit board.

A flameproof housing (202) includes a display aperture (212), a shoulder (207) adjacent to the display aperture (212), a transparent panel (230) including an outer face (231) and a perimeter (232), and a fastener element (236) configured to hold the transparent panel (230) against the shoulder (207). A perimeter interface region (264) between the perimeter (232) of the transparent panel (230) and the interior surface (203) of the flameproof housing (202) creates a perimeter gap that does not exceed a predetermined flameproof gap limit and a face interface region (260) between the outer face (231) of the transparent panel (230) and the shoulder (207) creates a face gap that does not exceed the predetermined flameproof gap limit.

An assembly for attaching and detaching an electronics module from a base includes a feedback assembly that provides an operator with tactile feedback on the relative positioning of the module with the base during attachment or detachment of the module to or from the base. The feedback assembly includes cams on the electronics module and a follower attached to an end of a spring arm on the base. The spring arm forms a portion of a wall that guides movement of the module along the base during attachment or detachment of the module.

A measuring device with at least one sensor and at least one transmitter housing, wherein the transmitter housing has at least one terminal space and an electronics space adjacent to the terminal space and connected via a partition wall, wherein at least a first electronic device for the connection of supply and/or I/O lines is arranged in the terminal space and wherein at least a second electronic device is arranged in the electronics space with electronics for controlling the sensor, wherein the first electronic device and the second electronic device are electrically conductively connected to one another via a contacting unit, wherein the contacting unit is removably inserted into a recess of the partition wall. The A measuring device that is simple to produce and whose components can be particularly easily replaced is achieved by the contacting unit being firmly connected to the first electronic device.

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.
