18-Circuit Vertical Shrouded Header — Tin-Plated
The 15-80-0181: This is a Molex C-Grid vertical shrouded header, 18 circuits, with tin-plated contacts. The vertical orientation places the pin axis perpendicular to the PCB, suiting board-edge or mid-board layouts where the mating receptacle approaches from above. Tin plating on the mating interface is rated for moderate cycle counts — typical for equipment that sees infrequent disconnect, such as power supplies or control panels.
