The Molex 2130321001 is a two-piece backshell from the JUWEL series, size 1, designed to fit standard D-sub connectors with 9 positions or the high-density 15-position (HD15) shell. It is a shielded, zinc die-cast accessory — not a connector itself — that clamps over the cable exit of a D-sub to provide strain relief, EMI containment, and a finished look at the cable-to-connector junction. The 180° cable exit routes the cable straight out the back, which suits panel-mount or cable-assembly applications where a right-angle exit would crowd the enclosure wall.
Shielding and Environmental Rating
The metal body provides continuous shielding around the D-sub solder bucket area, which matters when the cable assembly runs near switching supplies or data lines. The IP20 rating means the backshell is finger-safe against solid objects larger than 12 mm but offers no protection against moisture ingress — keep it inside an enclosure or a dry environment. Assembly hardware is included, so the two halves clamp together without sourcing extra screws or jackposts.
