What This Backshell Covers and How It Fits
The Molex 1727040100 is a two-piece metal backshell from the FMK, FCT 172704 series, designed to fit standard DB25 D-sub connectors and high-density 44-position D-subs that share the same shell size B footprint. It provides 360° shielding for the cable-to-connector transition, with a zinc die-cast body and nickel plating that gives a consistent ground path and corrosion resistance.
What's in the Box — Hardware Included
This backshell ships with the assembly hardware, cable clamp, and strain relief already included — no separate hardware order needed to complete the cable assembly. The 4-40 mating screws are the standard thread for DB25 backshells, securing the two halves together and to the D-sub connector. The cable clamp grips round cable jackets evenly, and the two-piece design means you can terminate the D-sub connector first, then assemble the backshell over the wiring — a field-serviceable approach that saves a trip back to the bench.
