EMI/RFI-shielded Faraday cage doors
EMI/RFI/EMP-shielded doors for use in Faraday cages and EMI/RFI shielded rooms
Holland Shielding Systems BV specializes in designing and manufacturing standard and custom EMI/RFI-shielded doors for EMI/RFI-shielded rooms and Faraday cages. High performance single and double knife fingerstrip doors in sliding, swinging and even double swinging implementations are some of the many possibilities. Our engineers will be happy to help you find the best solution possible.
We also produce sets to shield doors with gaskets at the top and sides, while the bottom can be provided with a electrically conductive copper brush and doorstep. See Standard modified doors.
Virtually every type of door can be provided in a swinging or sliding implementation.
The fully automatic EMI/EMP/RFI-shielded sliding doors are designed for RF and EMP-tight enclosures. They can be integrated in EMI/RFI-shielded rooms and are also suitable for other types of shielding.
There are two steps involved in opening the sliding door:
The movements of the door and ramp are fully automated; they are operated electrically and pneumatically. Each opening and closing of the door has a self-cleaning effect on the contact surfaces (fingerstrips and knife of the door). Sizes range from 1 x 2.1 meters to a 'jumbo-sized' door of 8 x 12 meters.

The fingerstrip swinging doors are well known for their high shielding performance and are used in prefab cages as well as in our Mu-Copper systems. We manufacture single fingerstrip doors for medium shielding performance and double fingerstrip doors for high shielding performance (reductions up to 140 dB). Delivery from stock is possible in various dimensions. In EMC applications, ferrite tiles can be affixed to the standard door leaf.
To achieve the various attenuation levels required, we have several types of swinging door in our assortment.

For applications with a performance up to 40-60 dB we can upgrade a wooden door to a shielded door. The modified wooden door can be supplied in a sliding or a swinging implementation. The wooden modified door is used in hospitals, e.g. in EEG, EMG, and measurement rooms.
