CHAMP .085 50-Position IDC Receptacle
The outer shroud contacts and two-row layout are typical of the CHAMP.085 family, which uses a 0.085-inch pitch between contacts. The free-hanging (in-line) mounting style and IDC termination mean this receptacle is wired by pressing the ribbon cable into the slot with a tool — no individual crimp terminals. The unthreaded flange feature allows panel-mounting with a screw or bolt through the housing shell for strain relief in a fixed installation.
Tin-plated contacts at a lower price point would wear faster under repeated mate/unmate duty; the gold here buys extended reconnect life.
