EMI and FCC Heavy Duty Enclosures Heavy Duty Catalog Section (PDF - 4.27 mb) NEW - High end shielding announcement  Shielded enclosures allow you to meet a wide variety of requirements for EMI/RFI suppression including: Mil Spec 285 TEMPEST FCC Part 15 European VDE The EMI & FCC Heavy Duty product lines come in both vertical racks and sloped front consoles (15 & 30 degree). It is designed with double ledge, double plane corner construction which make it the strongest cabinet in the industry, capable of carrying 3000 pounds of equipment.

The EMI racks are constructed of 400 Series Stainless Steel, which is galvanically compatible with gasket material. We offer R1, R3, R4 & R5 versions of our racks. R1 racks are shipped ready for user installed gasketing. The gasketing material for R3 racks is beryllium copper spring-finger gasketing; this gasketing does not absorb moisture or support fungus growth, it will not take a compression set over a period of time, it is not affected by air, ozone, ultraviolet and nuclear radiation or solvents and can not flake or break into small conductive pieces that can short out electronics. R4 racks are gasketed with a silver coated nylon gasketing. R5 racks have both beryllium copper gasketing and silver coated nylon gasketing. The R3 and R5 racks can meet most TEMPEST and EMP requirements. Additionally there are two stainless steel studs in the lower rear of frames to assist in grounding.

The FCC racks are made of 14 gauge steel. Silver braid gaskets are attached to the frame with a conductive, pressure sensitive adhesive. The gasket’s foam core offers low closure force. All surfaces of doors, panels and frames that come in contact with EMI gaskets have a metallized corrosion resistive surface. FCC racks provide versatility, reliability and cost efficiency while still meeting FCC, CE Mark or other commercial requirements.

EMI & FCC cabinets feature panel mounting angles made from 3/16" steel, 50% thicker than the average used in the industry. Horizontal support channels are removable because of the extreme strength of the frame. Positive door latching hardware, not magnetic or velcro stripping, is standard.

Accessories

EMI & FCC Heavy Duty racks are designed to be modular and flexible, a wide variety of accessories are available. Here is a small sample:

Options

Shock and Vibration The Heavy Duty Cabinet has been tested to Mil-Std 810D, section 514.3-7,8 and 9, which simulates 20 years of rough service in a mobile application. This cabinet was also tested to Mil-Std 901 which simulates a 10g hammer hit. These test was successfully passed by the Heavy Duty, EMI, and FCC product lines. This option is available by adding a simple hardware kit.
