Contact system and plating
The 66207-012LF is the 16-circuit member of Amphenol ICC's Quickie™ shrouded header line, a board-to-cable/wire interconnect. The 3-wall shrouded housing with latch lock/eject hooks protects the pins during mating and holds the cable-side receptacle against vibration.
Keying slot and mounting flange on the 0.642" (16.30mm) tall insulator align the connector to the board cutout and prevent mis-mating.
