The 1-1734839-0: The contacts are top-side, so the FPC inserts from above the connector body. Rated at 0.5A per contact and 250V, it handles signal-level duty in compact electronics—think display interconnects, sensor boards, or control panel ribbon runs.
Pitch, positions, and FPC thickness—what fits
The 0.50mm pitch is standard for fine-pitch FPC interconnects. The connector accepts FPC thickness of 0.30mm—any thicker and the ZIF mechanism won't close fully. The FPC cable end must be tapered per the TE specification to clear the actuator. With 10 positions, this is a narrow connector for low-signal-count buses. The right-angle SMT mounting keeps the connector profile low at 2.05mm above the board, useful for tight stack-ups.
