What this cap does in the assembly
The TE Connectivity 2407269-1 is a protective cap for the CPC series, sized for shell size 11 plug connectors. It covers the mating face of the CPC plug when unmated, keeping debris and handling damage off the contacts. The orange polyethylene body makes the cap visible on a harness or panel — easy to spot if left off before mating.
This cap fits CPC size 11 plugs only — it matches the shell diameter and latch geometry of the plug housing. It is not a receptacle cap; the retention features are keyed to the plug's outer profile. If you are capping a CPC receptacle, you need the corresponding receptacle cap in the same shell size.
Material and environment
Polyethylene is a general-purpose dust-cap material — it resists moisture and common solvents but is not rated for continuous outdoor UV exposure or high-temperature zones near an engine or exhaust. The orange color is a standard TE high-visibility option, useful on a crowded harness board or in a service kit where the cap needs to stand out against black housings and black wire.
