The Molex 2130321031 is a size 1 JUWEL two-piece backshell for standard D-sub connectors, designed for 180° (straight) cable exit. It's a shielded, zinc die-cast assembly in blue with silver hardware, rated IP20 for indoor cabinet use. This backshell fits both 9-position and high-density 15-position D-sub connectors sharing shell size E — a single SKU that covers two common footprints.
Assembly hardware is included with the backshell, so there's no separate fastener to source for the cable-clamp and shell-mount screws. The two-piece clamshell design clamps onto flat cable (per the cable type listing) and provides strain relief at the connector exit point.
The zinc die-cast metal body with full shielding makes this backshell a fit for environments where radiated EMI needs containment — think industrial control cabinets, test equipment, or data-com panels where the cable shield must be terminated to the connector shell. The IP20 rating means it's finger-safe but not sealed against moisture or dust ingress, so it belongs inside an enclosure, not on an outdoor cable run.
This backshell accepts both 9-position standard D-sub and 15-position high-density connectors using shell size E.
