Shielded doors

Shielded doors for the use in faraday cages and shielded room

Holland Shielding Systems BV is specialised in designing and manufacturing standard and custom doors for shielded rooms and Faraday cages. High performance single and double knife fingerstrip doors in sliding, swing and even double swing implementations belong to the possibilities. Our engineers will assist to find the best solution possible.

We also produce sets to shield doors with gaskets on top and sides, while the bottom is provided with a conductive copper brush and doorstep. See standard modified doors.

Nearly each type of door can be provided in swings implementation or a sliding implementation.

Sliding doors

The fully automatic shielded sliding doors are designed for RF and EMP-tight enclosures. It can be integrated in shielded rooms as well as for other types of shielding.

The opening procedure of the sliding door is performed in two steps:

Unlatching of the contact spring system and outward movement;
Sideway movement of the door leaf.

The movements of the door and ramp are fully automatic; 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' door of 8 x 12 meters .

Options

Fire proof
Automatic closing
Gas tight
(Automatic) locking system

Swing doors

The fingerstrip swing 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 (reduction up to 140 dB). Delivery from stock in various dimensions. In EMC applications, ferrite tiles can be affixed to the standard door leaf.
