ETS-Lindgren's RFD-60 doors are designed for easy, lightweight operation and performance tested in accordance with IEEE-299 and MIL-STD-285.
The RFD-60 door system consists of frame and door in two standard sizes:
The patented hinges allow the final closing of the door allows the door leaf to enter the door pocket parallel to the door frame maximizing the RF performance and also permit a typical swing when the door is opened wide. The final RF seal is obtained by a cam mechanism at both edges of the door. The door has two recessed contact fingers. The door is equipped with bearings increasing the ease of opening and closing the door. The door provides options for mechanical and welded attachment to the shielding system. The door can also be equipped with a pneumatic operating system to ease the operation of the door further. The door is still opened manually; the pneumatic option simply releases/closes the RF-tight locking.
