What This CPC Cap Covers and Why It Matters
The TE Connectivity 1-2407269-2 is a protective dust cap from the CPC (Circular Plastic Connector) series, designed to cover an unmated connector half during shipping, storage, or panel installation. It fits both a shell size 11 CPC receptacle and a shell size 13 CPC plug — one cap that covers the two most common panel-mount and in-line connector sizes in the series. That dual-fit means you stock one SKU instead of two, and you don't chase the wrong cap when a size 11 receptacle and a size 13 plug are both on the same harness. The cap is molded from black polyethylene (PE), a material chosen for its combination of flexibility and impact resistance — it snaps over the connector face without cracking and stays put during handling, but can be removed cleanly when it's time to mate. The black color is standard for CPC accessories and matches the industrial look of the mated connector assembly. This is a protective cover, not a mating connector — it seals the contact cavity against dust, debris, and light splash during the period the connector is unmated. It is not rated for continuous submersion or high-pressure washdown; its job is keeping the pin cavities clean between installation steps or during transit.
Shell Size Compatibility — One Cap, Two Connectors
The 1-2407269-2 covers shell size 11 on the receptacle side and shell size 13 on the plug side. In the CPC series, shell size 11 is the common panel-mount receptacle size (used for 4- and 7-position inserts), while shell size 13 is the standard in-line plug size (used for 4- and 7-position inserts as well). The cap's internal geometry is stepped or contoured to grip both sizes securely — it's not a universal cap that loosely fits everything, but a precision-molded cover that engages the specific shell diameter and latch profile of each. Compared to a single-size cap (e.g., a cap that only fits a size 11 receptacle), this dual-fit part reduces inventory complexity for a harness shop that builds assemblies with both shell sizes. The trade-off is that it won't fit a size 11 plug or a size 13 receptacle — those are different shell-size combinations not covered by this cap.
No stock-holding claim; the cap is procured through independent distribution per the buyer's quantity and delivery window.
