50-Position Shielded Backshell for AMPLIMITE .050 III D-Sub Connectors
The TE Connectivity 5749193-1 is a two-piece backshell from the AMPLIMITE.050 III series, designed to fit a 50-position D-sub connector with a D shell size. The backshell is shielded, constructed from metal (zinc) with a nickel over copper plating, giving it the conductivity needed to bleed EMI from the cable braid to the connector shell. The silver finish is the standard appearance for this plating combination. It ships with the assembly hardware and strain relief included — the spring lock secures the two halves together without loose screws, and the strain relief clamps the cable jacket to prevent pull-out forces from reaching the solder buckets or crimp contacts inside the connector.
Fit and Compatibility — Which Connector It Covers
This backshell is listed as compatible with both a standard 50-position D-sub and a high-density 78-position D-sub that share the D shell size. The 50-position count on the backshell refers to the connector it fits, not the number of cable conductors — the shell cavity is sized for the D footprint.
