What This Backshell Covers
The TE Connectivity 1478762-9 is a two-piece D-sub backshell from the ADK series, designed for 9-position D-sub connectors with shell size E. It is a shielded, metal backshell — the zinc die-cast body carries a nickel plating, giving the shell good corrosion resistance and a consistent ground path for the cable braid. The 180° cable exit routes the round cable straight out the back, which suits panel-mount or bulkhead installations where the cable runs perpendicular to the panel face.
Hardware Included
This backshell ships as a kit that includes the mating screws (4-40 thread), assembly hardware, grommets, and strain relief. The 4-40 screws are the standard D-sub jack-screw thread — they engage the threaded inserts on the mating D-sub connector to lock the assembly together and prevent the backshell from loosening under vibration. Having the grommet and strain relief in the package means one line item on the BOM covers the full cable exit seal and pull-relief, rather than sourcing those parts separately.
Cable and Connector Fit
The backshell is listed for round cable types and accepts a 9-position D-sub connector with shell size E. TE notes this backshell as compatible with both 9-position and HD15-position D-sub connectors — the HD15 uses the same shell size E as the standard DE-9, so the backshell fits both if the cable bundle fits the grommet. The 180° exit means the cable exits straight through the backshell, so the assembly height behind the panel is the length of the backshell plus the cable bend radius.
