What This Backshell Covers
The TE Connectivity AMPLIMITE 5747099-1 is a two-piece plastic backshell for D-subminiature connectors, designed to fit shell size A — the standard shell for 15-position D-subs and high-density 26-position D-subs. It provides a shielded enclosure around the solder-bucket or IDC termination area of a D-sub connector, with a 180° straight cable exit for round cable assemblies. The backshell includes the 4-40 mating screws and the full assembly hardware and strain relief, so no separate hardware order is needed to complete the cable-end assembly.
Shell Fit and Cable Routing
This backshell mates with any standard D-sub connector using shell size A — that covers both the 15-position standard-density D-sub and the 26-position high-density D-sub. The round cable entry accepts standard round-jacketed D-sub cable bundles. The shielded construction uses a nickel-over-copper plating on the plastic shell to provide EMI containment around the termination area — relevant for signal integrity in industrial or data-communication environments where radiated emissions or susceptibility is a concern.
Included Hardware and Assembly
The 5747099-1 ships with the 4-40 mating screws pre-installed in the backshell halves, plus the full assembly hardware (screws, washers, and strain-relief clamp) to secure the cable and close the backshell around the D-sub connector. The thermoplastic body is rated for the operating temperature range typical of commercial D-sub applications. No additional hardware is required to complete the assembly — the backshell is a complete kit for the cable end.
