A range of low cost plastic EMC vents for use with 40, 60, 80, 92 and 120mm fans is available from Kemtron. These provide RFI/EMI shielding where applications demand a low cost solution, whilst still providing an adequate shielding performance for most commercial applications of over 50db up to 10 GHz.
The Hi-impact ABS UL94V-0 fire retardant moulding is fitted with one layer of 3.2mm cell x 6.35mm thick aluminium honeycomb and an electrically conductive nickel/copper fabric over foam gasket to ground the honeycomb to the metalwork. As well as providing RFI/EMI shielding, the fan vents ensure good thermal management of an electronics enclosure, ensuring a good exchange of air. The vents have four countersunk holes to suit standard fan mountings, so are easy to fit with no modification.
Kemtron manufactures and supplies a full range of RFI/EMI shielding gaskets and components – including electrically conductive elastomers, knitted wire mesh gasket strips, conductive fabric over foam gaskets, beryllium copper finger stock, shielded optical windows, and more.
