It routes the cable at a 90° angle from the connector axis. This backshell is part of the 165X series and carries a base product number of 165X134. It ships in Bulk packaging, which suits both prototype builds and production runs where you want the same part number across both. ## What It Fits and What Comes with It The 165X13439XE is compatible with both standard 25-position D-sub connectors and high-density 44-position D-sub connectors that use a size B shell. That dual compatibility is useful when your panel has a mix of standard and high-density ports — one backshell stock code covers both. The shell size B is the same footprint used by standard 25-position D-subs, so the backshell aligns with the connector mounting holes without adapters. It ships with 4-40 mating screws already included — no separate fastener line item on the BOM. The assembly hardware and strain relief are also part of the package, so the backshell arrives ready to install onto a terminated connector. The strain relief clamps onto the round cable jacket, taking the pull load off the solder or crimp connections inside the shell. ## Build Notes for the Harness Bench Because this is a two-piece backshell, you terminate the D-sub connector first, then assemble the backshell halves around the cable and screw them together. That sequence is standard for field-terminated cables — you don't need to thread the cable through a one-piece shell before terminating. The 4-40 mating screws thread into the D-sub connector's threaded inserts. The PBT shell handles that without stripping.","metaTitle":"165X13439XE Backshell, 25-Pos, 90°, Black, Mating Screws","metaDescription":"165X13439XE D-sub backshell, 25 positions, 90° cable exit, black PBT, includes 4-40 mating screws and strain relief.
