ETS-Lindgren's iRFD-100 doors are designed for high performance operation, made in accordance with MIL-STD-285
ETS-Lindgren's iRFD-100 doors are designed for high performance operation, made in accordance with MIL-STD-285. The iRFD-100 door system consists of frame and door in two standard sizes, 900 mm x 2100 mm (3 ft x 7 ft) and 1200 mm x 2100 mm (4 tf x 7 ft).
The patented hinges allow the final closing movement to be parallel to the door frame and also permit a normal circular trajectory when the door is opened wide. RF seal is obtained by cam followers at both edges of the door. The door has four recessed contact fingers.
The door is easy to operate as the opening and closing mechanisms are equipped with bearings. The door can also be designed for welded installation to the shielded enclosure.The door can be equipped with pneumatic RF-tight opening/closing system for lighter operation. In this case, if the door must be opened manually the operation system just releases the RF-tight locking.
For the attenuation test, ETS-Lindgren chose the least favorable point of the door.
