The F31L-1A7H1-11045: It uses a zero-insertion-force (ZIF) slide-lock actuator to secure the cable — the slide lock holds the FPC against the bottom contacts without requiring insertion force on the cable itself. The 30 mating cycles limit it to one-time assembly or infrequent service access.
Gold contact finish at 1.97 µinch (0.050 µm) over phosphor bronze base — the gold layer provides corrosion resistance for the rated 30 mating cycles. In a typical assembly that mates once at build and once during field service, the contact interface stays within its wear budget. The natural housing colour and black actuator are visual identifiers for the 45-position variant.
Termination is solder-only — the connector is surface-mounted to the PCB, and the FPC/FFC is inserted into the ZIF clamp. No crimp or press-fit option exists for this part.
The closest peer by position count is the 55-position F31L-1A7H1-11055 and the 57-position F31L-1A7H1-11057, both sharing the same pitch, height, and contact finish.
