MAJR offers a wide variety of EMI/RFI Vent Panels in standard sizes which can reduce lead time and set up charges for our customers. However, we understand that some shielding requirements need special designs. MAJR’s team of engineers can assist with applications requiring special mounting or dimensions.

For most applications, aluminum Code-32 honeycomb will provide a degree of attenuation that will be within specification limits, however, for the lower frequency magnetic (H Field) it may be necessary to specify MAJR’s Tin Plated Steel, Code-44 honeycomb. Although heavier in weight than aluminum, an increase of 20-40dB H-field shielding effectiveness can be achieved in the lower frequency range by the use of the higher permeable – Code 44 grade honeycomb.
