RF shielded doors

The shielding characteristics of Comtest RF shielded doors are achieved using a double knife edge, matching quadruple beryllium copper finger contact strip. The RF shielded doors are equipped with a unique parallel closing mechanism and patented locking and latching system. All Comtest shielded doors are available in manual, semi- and full automatic operation. The standard range of swing and sliding doors consists of many different models and can be designed with a 50mm low threshold. In EMC applications both ferrites and absorbers can be affixed to the door leaf.

Benefits of the unique design

For the swing doors a double pivoting hinge, parallel closing system is used in order to ensure long life time of the double row finger stocks mounted in the doorframe. For service and maintenance the door mechanics can be reached by removing the front cover of the door. Since this is not an essential part of the shielding it facilitates all maintenance work without affecting the shielding performance of the facility.

Manual, semi- and full automatic operation

All the RF shielded doors can be delivered in manual, semi- and full automatic operation. Comtest semi- and full automatic RF shielded doors are 100% electrical operated. The benefit of electrical doors is that they are more reliable than pneumatic systems. In case of mains power breakdown, automatic doors can be operated from the internal rechargeable battery system or using a manual handle.

RF shielded door options

The following options are available for all RF shielded door models.
• Manual, semi- and full electrical operation.
• Door status switch (inter lock) to connect test room entrance doors with amplifier rooms
• Security access system using keycard validation systems. The shielded door can be operated upon validation
of the card or any other security checking system connected to the door electronics.
• Non-conductive (internal) door handle for anechoic applications
• On the inside an emergency exit light can be installed.
• On the outside a test in progress light can be installed.
• For high security applications the doors can be equipped with anti-burglary mounting materials.
• Door frames are suited for modular pan-type, sandwich or welded enclosures
• Removable access platform (slope)
• Full automatic up/down platform for flat (threshold less) entrance
