EMI/RFIShielded Doors & Windows

Global EMC’s high-performance shielded doors are carefully designed and manufactured to ensure maximum performance and durability. Built in the UK, our custom shielded doors and windows for anechoic and faraday test facilities can be supplied with single or double knife-edge finger strips. We can also manufacture shielded doors that are fireproof, soundproof or “clean room” specific.

Shielded Doors


Global EMC’s high performance shielded doors are one of the fundamental parts of any anechoic, Faraday cage or shielded room. Each door is carefully designed and manufactured by Global EMC to ensure maximum performance and usability.

All doors are low maintenance due to the unique design of almost zero friction mechanism. Our high-performance twin knife edge door (HPD7000) also gained industry recognition and was awarded a Government smart award for design and development.

Sliding Doors


Global EMC’s high-performance sliding doors are one of the fundamental parts of any anechoic, Faraday cage or shielded room. Each door is carefully designed and manufactured by Global EMC to ensure maximum performance and usability. The mechanism interfaces are all on roller bearings for smooth X and Y motion of the door away from the chamber and sliding across the chamber opening. Upon closure operation, the sliding door leaf meets the frame and pulls the door leaf in to make an RF seal.

The latching is provided by a parallel acting carriage having an up and down motion, this ensures the four-point latch always keeps the door normal to the frame so that miss-alignment is negated. A safety feature is provided to the door via an external mechanism so that if damage occurs to the door, external latches can be unscrewed and the door manually opened. The door comes complete with emergency back-up systems so that in the event of a power failure it is still possible to operate the door.

The size of the door is bespoke to requirements but can be from 900mm (W) x 2000mm (H) pedestrian door to 6000mm (W) to 6000mm (H).

05


Safety sensors to stop.

06


Indicator panels to show open or closed state.

Shielded Windows


Global EMC’s shielded windows provide a solution for Faraday cages or shielded rooms preserving the integrity of the electromagnetic shielding. The window can be used for observation, monitoring or for natural light inside the room. Shielded windows contain a highly conductive layer of film that is grounded to the shield of the Faraday cage.

Each window is made to bespoke measurements to suit the application but standard measurements are: 600 mm (H) x 600mm (W) x 7mm (D).

Each window is manufactured in a galvanised steel frame and using a conductive gasket that creates continuity across the opening.

A second layer of glass can be incorporated into the frame to give laminated glass, shatter proofing, insulating or bullet resistance to BR-1S/ BR-1NS.

The visibility through the shielded window is comparable to that of smoked glass.
