EMI/RFI-Shielding Enclosure Vents
These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.
Screw through the vent frame to mount on the surface of your enclosure. A shielded foam gasket fills the gap between the enclosure and the vent.
Also known as attenuation, interference reduction at frequency measures how much interference is blocked. These vents have high attenuation and work for most applications.
