55-Position FPC Connector — 0.50 mm Pitch, ZIF Slide Lock
The F32R-1A7H1-11055: This is a 55-position FFC/FPC connector from the Amphenol ICC (FCI) Aorora F32R series, on a 0.50 mm pitch. The gold flash contact finish (1.97 µinch) and phosphor bronze base support signal-level duty in compact board assemblies.
Cable Fit and Termination — ZIF Slide Lock, 0.30 mm FPC
The actuator slides open to insert the cable, then closes to clamp the contacts — no insertion force on the cable, which avoids pad damage on thin flex circuits. The slide lock also holds the cable under vibration, preventing the back-out that can occur with a simple friction latch. The connector uses bottom contacts, meaning the cable's conductive pads face down toward the PCB. The right-angle orientation routes the cable 90° from the board edge, which is typical for panel-to-board links in display or sensor modules.
Position Count Cross-Reference — 55 vs 54 vs 57
The only difference is position count: 55 positions here, versus 54 positions on the F32R-1A7H1-11054 and 57 positions on the F32R-1A7H1-11057. If your BOM calls for 54 or 57 circuits, those are direct siblings with identical footprint and mating interface — no board layout change beyond the cable width.
