RFI/EMI Shielded Nut Assembly 890020

Description

The 890020 RFI/EMI Shielded Nut Assembly is intended to provide RFI/EMI shielding for TA796-P, TA797, and TA820 series valves. The honeycomb plug allows air to pass through and is joined to the housing with silver-filled conductive epoxy to form a Faraday cage. This protects the interior of the container from unwanted radio frequency and electromagnetic radiation. The plug and the housing are both made of MIL-DTL-5541, Type II, Class 3 conversion coated aluminum.

To complete the Faraday cage, the interior surface of the container must also be conductive. When the 890020 is installed, this surface contacts a fluorosilicone base conductive gasket, which creates a conductive path between the container wall and the housing. Other gasket base materials are available upon request.

Four grooves in the wall of the nut provide a convenient gripping point for a hook spanner wrench for tightening.

Custom RFI/EMI Shielded Nut Assemblies offering higher attenuation through the use of drilled holes or honeycombed aluminum are also available. Similar nut assemblies are available for AGM's TA238-R, TA292-R, TA294-R, TA330, TA333-R, TA225, TA770-R, and TA790 series valves as well.
