RF Connector Captivation

Coaxial Components Corp., the highly-principled manufacturer (also known as Coaxicom) completed a design changeover on select connectors. All connectors with mechanical captivation deemed inadequate for specific applications have been converted to epoxy captivation. Part numbers are the same but customers will notice the following changes.

–  .060 dia cross hole containing vary flex (non conductive) epoxy (used to captivate the internal components).  Epoxy captivation offers the most rigid captivation of all.  It’s ideal for applications where the contact is soldered directly into an element which may be damaged by rotational displacement of the center contact. Epoxy captivation with conductive epoxy back-fill preserves all the advantages of epoxy captivation such as exceptional durability and provides improvement in RF leakage for better overall performance.

–   No movement of the internal components 4 in/oz radial & 10 lbs axial (mechanical captive design was 0 radial & 7 lbs axial)

–   RF leakage -60 db (not noticeable in non-emi gasket designs)

This update is an improvement for receptacles utilizing tabs, small diameter pins and blunt posts.  See diagram below for captivation comparison.
