The free-hanging (in-line) body and mating-side flange with M2.6 screw holes and latchblocks mean this plug is designed for a panel-mount or rack-mount receptacle, not for board-edge soldering — the screws and latches take the cable strain and vibration load, not the contacts. Gold contact finish at 7.87 µin (0.200 µm) is a solid commercial-grade plating for a high-density IDC connector. The gold layer is thick enough to prevent base-metal exposure through the wiping action of IDC termination, which is the real failure mode in a mass-terminated harness — a tin-plated contact in the same class would risk oxide build-up at the wire-to-contact interface over time. The IDC termination accepts standard 0.050-inch pitch ribbon cable (typically 28 AWG stranded or 30 AWG solid); the insulation displacement forks pierce the cable insulation on the wire side, so no stripping or soldering is needed. The flange with M2.6 screw holes provides a positive mechanical lock to the mating connector, and the latchblocks on the mating side engage with the receptacle housing to prevent accidental unmating under cable pull.","metaTitle":"Hirose DX31A-80P(50) 80-Pin IDC Plug, Miniature High Density","metaDescription":"Hirose DX31A-80P(50) 80-position IDC plug, Miniature High Density series.
