It clamps over the cable shield braid at the back of a D-sub backshell, completing the 360° shield path from the cable to the connector shell. The stepped inner profile fits the three common shell sizes — DB9, DB15, and DB25 — so one ferrule covers the whole harness family. It is an accessory, not a signal-carrying component; the ferrule itself carries no electrical rating beyond the shield continuity it provides. ## Shielded Construction and Series Compatibility The ferrule is explicitly listed as shielded, meaning it is designed to maintain the EMI/RFI shield integrity when mated with a shielded backshell and cable. It is compatible with any AMPLIMITE HD-20, HDE-20, HDP-20, or HDP-22 D-sub connector — the same family that covers standard-density and high-density shell layouts. The 9 ~ 25 position range maps directly to the shell sizes: DB9 (9 positions), DB15 (15 positions), and DB25 (25 positions).","metaTitle":"TE 3-747579-0 AMPLIMITE Shielded Ferrule, DB9/15/25","metaDescription":"TE 3-747579-0 AMPLIMITE HD-20/HDE-20/HDP-20/HDP-22 shielded outer ferrule for DB9/15/25 D-subs.
