As the threat of IEMI or EMP attacks becomes more real and the awareness of the risks rises, the necessity of shielded racks and/or datacenters increases. Holland Shielding offers shielded racks which can be fully customized to your requirements.

Attenuation levels

We have 2 standard performance levels for our shielded racks, so you can pick the type of rack that will suit your application.

Level 1: This type of rack is based on the well-known racks in the market and optimized for the shielding of your equipment with our in house produced shielding materials. This rack will give you the basic protection and will reduce the incoming attack up to 10.000 times.

Level 2: The ultimate shielding will come from our racks which are a spin-off off our prefab Faraday cages. These racks are exceeding most shielding effectiveness standards and offer a performance over 120 dB.

RF shielded rack structure
  • IEMI (Intentional Electromagnetic Interference)
  • Eavesdropping
  • Solar storms
  • EMP attacks
  • MIL-STD-188-125
  • Radiated attacks
  • Lightning
  • NSA 94-106


All our racks can be fully customized to your requirements. Just note that every opening or cable is going to be a leakage in the RF shielding of the rack. For this purpose we have power and signal line filters.

Most integrated options are:
  • Power-line filters
  • Signal-line filters
  • Ventilation honeycombs
  • Waveguide
  • I/O panel (BNC-, SMA-, N-Connector)
  • 7894 UDP data-line filter
  • 7896 USB 3.0 optical converter
  • Fixed/sliding shelve
  • Etc.

RF shielded racks honeycomb ventialation panel cooling

For extra power ventilation extra fans with shielded Honeycomb ventilation panels can be attached on the back of the rack

RF shielded rack mesh window door transparent

The glass in the door is equipped with a very fine electrically conductive mesh, which you can easily see through, but which guarantees a very good shield.

RF shielded rack data power line filter

Each rack can be equipped with the inputs and filters you need. Think of data connections such as USB and Ethernet, but also filtered power feeds for the device inside the racks.

We deliver relatively simple shielded boxes for small studies to large EMI and FCC heavy-duty shielded enclosures.

Our EMI shielded racks are constructed with our patented Mu-ferro series plate material, which is galvanically perfectly compatible with our EMI shielding gasket materials. This combination results in a very high shielding performance, also in the long term.

Our Shielded enclosures allow you to meet a wide variety of requirements for EMI/RFI suppression including:

  • Mil Spec 285
  • FCC Part 15
  • European VDE
  • I/O panel (BNC-, SMA-, N-Connector)
  • 7894 UDP data-line filter
  • 7896 USB 3.0 optical converter
  • Fixed/sliding shelves
  • Etc.
