What This Ferrule Does in the Assembly
The TE Connectivity 520433-1 is a ferrule — a crimp-on or slip-on accessory — designed for use with SDL connectors. It serves as a strain-relief and cable-management component, fitting over the cable jacket at the connector back end to protect the termination point from flex and pull forces. The gray color helps with visual identification on the harness or in a bin, and it ships in bulk packaging for volume assembly work.
