Pitch and Position Fit — 1.00 mm, 12-Way Top-Contact ZIF
The SFW12R-2STE1LF: The right-angle SMT orientation places the FPC parallel to the PCB, keeping the mated height above board at 0.106" (2.70 mm).
Current, Temperature, and Contact Finish — Signal-Duty Limits
Tin plating on the contacts keeps cost low but limits mating cycle life to 20 cycles; after that the tin oxide layer builds and contact resistance drifts. For applications that see frequent cable swaps — test fixtures or field-replaceable modules — a gold-plated sibling is a better fit. The solder retention feature helps keep the connector in place during wave or reflow — no separate board lock needed for most applications.
Cable Compatibility and Termination — FFC/FPC Thickness Window
Accepts FFC or FPC with a thickness of 0.30 mm or 0.33 mm — the two common standard thicknesses for 1.00 mm pitch cables. The top-contact configuration means the cable's conductive pads face upward when the connector is mounted; the ZIF mechanism requires no insertion force, so the cable pads are not scraped on entry. The slide lock pushes the actuator forward to clamp the cable; a distinct click confirms full engagement. Termination is solder — the right-angle SMT pads are on a single row, which makes hand-solder inspection straightforward under magnification. The tape-and-reel packaging (available in cut tape as well) feeds into standard pick-and-place for volume assembly.
Peer Comparison — 12-Position Top vs Bottom Contact
The closest sibling is the SFW12R-1STE9LF, which shares the same 12 positions, 1.00 mm pitch, 2.70 mm height, and tin finish — but uses bottom-contact configuration instead of top. The difference matters for cable routing: top-contact connectors let the FPC fold over the top of the connector, while bottom-contact routes the cable underneath. If your PCB layout has components or keep-out zones on one side of the connector, the contact orientation determines which cable bend direction fits. The SFW12R-2STE1LF (top contact) is the more common choice for board-edge ribbon exits where the cable runs away from the board surface. For a different position count, the SFW11R-2STE1LF (11 positions) and SFW14R-2STE1LF (14 positions) are direct pitch-and-height matches with the same top-contact ZIF design — only the circuit count changes. No pinout or footprint cross-compatibility beyond the same series.
