EMI/RFI Shielded faraday cage doors

EMI/RFI shielded sliding doors

The fully automatic EMI/EMP/RFI shielded sliding doors are designed for RF and EMP-tight enclosures. It can be integrated in EMI/RFI 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 .
