The TE Connectivity AMPLIMITE 5745833-9 is a two-piece plastic backshell for D-subminiature connectors, designed to terminate round cable with a 180° straight exit. It is shielded — the nickel-over-copper plating on the shell provides continuous EMI/RFI coverage when mated to a compatible D-sub connector. The backshell accepts 25-position standard D-sub shells and also fits HD44 shells (same Shell Size B footprint), giving it a wider cross-fit than a typical 25-position-only backshell. Assembly hardware is included: the 4-40 mating screws and the two-piece clamp halves are in the bag, so no separate fastener order is needed.
Shielding and Cable Exit — What the Ratings Mean
The shielded construction means this backshell is intended for environments where radiated emissions or susceptibility is a concern — industrial drives, test equipment, or data-communication panels. The nickel-over-copper plating provides a conductive path from the cable braid to the D-sub shell; for full shield continuity, the cable braid must be terminated to the backshell's internal clamp (not included in the bag — the clamp is part of the backshell assembly).
Hardware Included — No Surprises on the Bench
The bag contains the two-piece plastic backshell body, the 4-40 mating screws, and the assembly hardware — typically the screws and nuts that secure the backshell halves together. The 4-40 screws are the standard thread for D-sub backshells; they engage the threaded inserts on the D-sub connector's locking posts. No additional hardware purchase is required for a basic installation, though a cable clamp or strain-relief boot may be needed depending on the cable diameter.
