The TE Connectivity 1-332056-0 is a Coaxicon-series ferrule, built from copper with a silver finish. It's an accessory — not a connector body — designed for use with CPC (Circular Plastic Connector) connectors. On the harness floor, this is the part you crimp over the cable braid or shield before terminating into the CPC backshell, giving you a clean, repeatable ground path that doesn't fray or short against adjacent pins.
Why the Copper Body and Silver Finish Matter for RF Work
Copper gives you good conductivity for shield termination — it carries the return current without adding a hot spot. The silver plating keeps oxidation from building up at the crimp interface over time, which matters when that ferrule is the only ground reference between the cable shield and the connector shell. If you're terminating RG-type coax or shielded twisted pair into a CPC housing, this ferrule maintains the shield continuity through the connector.
