CPC Size 17 Plug Cap — Shell Size Defines the Fit
The TE Connectivity 3-2407269-2 is a protective cap designed for the CPC (Circular Plastic Connector) series, specifically for a size 17 plug. The shell size 17 is the critical dimension — it determines which plug this cap fits, and it is non-negotiable for a proper seal and mechanical retention. Molded from black polyethylene (PE), the cap provides basic dust and impact protection for the plug face when unmated, keeping the contacts clean during storage, transport, or panel maintenance.
