What This Backshell Covers and How It Fits
The TE Connectivity AMPLIMITE HD-20 5748676-2 is a two-piece shielded backshell for 15-position D-sub connectors using shell size A. It's built from nickel-plated zinc alloy — the standard metal body that gives you RFI/EMI shielding around the cable-to-connector transition. The 180° straight cable exit routes the round cable inline with the connector, which keeps the assembly profile low along the cable axis. This backshell comes with the 4-40 mating screws and grommets already included in the package — you're not hunting for hardware separately. The grommets provide the strain relief grip on the cable jacket once the two halves are closed.
Shielding and Hardware — What's in the Box
The nickel-over-copper plating on the zinc alloy body gives this backshell its silver appearance and provides the conductive path from the D-sub connector shell to the cable braid. The 4-40 threaded inserts are standard for D-sub jackscrew mounting — they pull the backshell tight against the connector face and maintain the shield continuity. The assembly hardware and grommets are factory-fitted, so the backshell arrives ready for cable termination without sourcing extra parts.
