Technical Guide to EMI/RFI Suppression in Electronic Cabinets

MI/RFI Shielded Cabinets
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.

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 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. Our R6 product meets and exceeds the NSA 94-106 standard.

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.

Equipto Electronics Corporation 
Equipto Electronics Corporation is a leading manufacturer of packaging products for the electronics industry. We design and manufacture a wide variety of standard equipment enclosures, from full-size cabinets to sub-racks, at our facility in Aurora, Illinois. Special customer needs are fulfilled by modifications to standard designs or by custom enclosures. As a diverse metal fabricator we have standard product lines, each consisting of multiple variations and accessories, based on the EIA RS-310 standard (often referred to as the 19 inch standard). Many of these products are covered by the company’s numerous patents.

Since the company's founding in 1960, our electronic packaging products have been modular in design. This modularity extends well beyond the EIA RS-310 ( 19" ) standard for maximum user flexibility. For example, equipment can be moved from a vertical rack to a sloped front console, work station or instrument cabinet without modification. By adding shelves, drawers, turrets, casters, lift bolts, standard or special panels, outlet strips, fans, blowers, an almost endless list of accessories and other options, our customers can usually create the perfect electronic enclosure out of a catalog of standard products. This saves time and money over a custom packaging solution. Many projects can be manufactured and shipped by Equipto Electronics in just five working days.

In addition, our experienced engineering staff works directly with customers to specify and design enclosures for special situations. Because of the flexibility of our components and our wide variety of standard products, requirements that may seem very special can often be met with relatively minor modification of standard products providing meaningful savings.

While the Equipto Electronics design staff can find solutions to virtually any metal packaging need for electronics, the company has developed special expertise in EMI-RFI shielding and in the robust construction necessary for enclosures to survive major seismic-events. These capabilities make Equipto Electronics a preferred supplier for military, civil government, power utility and other critical electronic applications. The same operational characteristics are also in demand in such fields as scientific research, medicine, oil exploration and transportation systems.
