The TE Connectivity AMPLIMITE HD-20 5748677-1 is a two-piece shielded backshell for a 9-position D-subminiature connector with shell size E. It routes the cable at a 180° straight exit, which keeps the harness running directly behind the panel — useful when the connector sits flush against an enclosure wall or backplane. The shell is nickel over copper for RFI/EMI containment, and the plastic insert is ABS. It ships in bulk with the assembly hardware included.
What hardware comes with the backshell?
The 5748677-1 includes the mating screws (4-40 thread) and the grommets as part of the assembly hardware. That means you do not need to source those separately — the backshell, the two shell halves, the screws, and the cable-entry grommet are all in the bag. The grommet compresses around the round cable jacket when the two halves are tightened, providing strain relief and completing the shield bond.
What mates with this backshell?
This backshell fits any standard D-sub connector with shell size E — that covers 9-position D-subs. The 4-40 threaded inserts on the backshell align with the jackscrews on the mating connector. The shield continuity depends on the metal-to-metal contact between the backshell halves and the connector shell; a good ground path through the shield requires the connector itself to have a metal shell.
