Abstract
A system and method for radio frequency (RF) sealing a door of an RF enclosure is disclosed. The door employs a two-axis gimbal system to provide two degrees of freedom as the drawer door makes contact with the RF enclosure. The two-axis gimbal system allows the forces applied to the sealing gasket to be uniform along the length of the seal. This enables uniform seal compression, and therefore, uniform RF isolation. The door is held rigid while the door gasket is not affecting a seal against the frame of the RF enclosure. As the door becomes engaged with the frame, multiple contact points of the drawer door are deactivated thereby allowing the drawer door to pivot near the seal centroid on a two-axis gimbal system. The two-axis gimbal system allows the RF seal to be applied uniformly across the length of the seal.
