The F3311A7H121024E200: This is a 24-position, 0.50 mm pitch FFC/FPC connector from the Aorora F331 series by Amphenol ICC (FCI). It uses a zero-insertion-force (ZIF) flip-lock actuator — lift the black polyamide (PA9T) latch, slide in the 0.30 mm-thick FFC, then snap the latch closed. The mated height above the board is 1.02 mm — low enough for tight stack-ups in handheld or portable equipment.
What the 3.00 µin gold finish means for your application
The contact finish is 3.00 µin (0.076 µm) gold over phosphor bronze. That is a light-duty plating — rated for 20 mating cycles minimum.
