The Molex 743201007 is a DVI-I Dual Link receptacle from the MicroCross 74320 series, carrying 29 contacts in a shielded steel shell. It supports both digital and analog video signals — the extra four contacts over a DVI-D connector carry the analog RGB and sync lines.
Rated 3A per contact at 40VAC, with gold-plated contacts that handle the rated current without excessive temperature rise. The 100 mating cycles are typical for a panel-mount video connector — enough for the life of a desktop monitor or projector, but not designed for daily hot-plug reconnection in a test fixture. The steel shield provides continuous EMI containment when mated with a shielded DVI cable assembly.
