After the contact is crimped onto the stripped conductor, the ferrule is crimped over the insulation jacket. This provides mechanical strain relief so that tugging on the wire does not pull the conductor out of the crimp barrel, and it also centres the wire inside the contact cavity for consistent insertion force. For harness shops building AMPLIMITE HDP-20 cable assemblies, using the correct inner ferrule is standard practice to meet contact retention specifications. ## Compatibility with AMPLIMITE HDP-20 Connectors The 6-745129-9 is listed for use with AMPLIMITE Series products, meaning it mates with the standard AMPLIMITE HDP-20 D-sub connector family. It is the inner ferrule — not the outer ferrule that goes over the contact assembly. The outer ferrule (a separate part number) crimps over the cable jacket after the contact and inner ferrule are in place, providing overall cable strain relief. Both are needed for a full AMPLIMITE HDP-20 backshell assembly, but this listing is specifically the inner piece.","metaTitle":"6-745129-9 AMPLIMITE HDP-20 Inner Ferrule","metaDescription":"TE 6-745129-9 inner ferrule for AMPLIMITE HDP-20 D-subs.
