0.50 mm Pitch, 24 Positions — FFC/FPC Signal Interconnect
The F31K-1A7H1-11024: This is an Amphenol ICC (FCI) Aorora F31K series FFC/FPC connector, 24 positions on 0.50 mm pitch, with vertical 1-sided contacts and gold plating rated for 30 mating cycles. Gold contact finish at 1.97 µinch (0.050 µm) over phosphor bronze gives reliable signal-level connections in repeated mating applications, though the 30-cycle rating means this is a low-mating-duty interconnect — fine for internal harnesses that connect once and stay.
Solder Retention and SMT Termination for Board Assembly
The 4.20 mm height above board gives a compact z-height budget for tight enclosures; the natural LCP housing and gray actuator are standard for the Aorora F31K series.
It is RoHS compliant with a UL94 V-0 rated housing.
