What This Backshell Covers
The TE Connectivity AMPLIMITE 5745833-1 is a two-piece backshell designed to terminate and shield the cable end of a 25-position D-subminiature connector. It accepts round cable and exits the cable straight out the back (180°), which is the standard orientation when the cable runs directly away from the panel or enclosure wall. The shell is shielded — the nickel-over-copper plating on the thermoplastic body provides a continuous ground path from the connector shell to the cable braid, which matters when you're routing signal lines near switching power supplies or motor drives. This backshell fits the standard shell size (Shell B) and is also listed as compatible with HD44-position D-subs that share the same shell footprint.
Checking the Fit Against a Sibling
The 5745833-1 is the shielded, 180° exit version for 25-position D-subs. If your enclosure has the connector mounted on the back wall with the cable running straight out, the 5745833-1 is the one; if the cable needs to turn 90° immediately to fit inside a shallow enclosure, the -2 is the better pick.
