Contact Side and Cable Fit
The 62674-121121ALF: This is a vertical, 1-sided contact FFC/FPC socket — the contact beams mate with pads on one side of the flex cable only. A flipped cable shorts the wrong row, so confirm the cable's pad side faces the actuator before insertion.
Sizing the Board Footprint
The 4.10 mm height above board leaves clearance for low-profile enclosures but requires the mating FFC to route vertically from the top of the connector. Surface-mount termination with kinked pins — the kinks provide a press-fit retention force during solder reflow, reducing tombstoning risk on the fine-pitch footprint.
