0.50 mm Pitch, 12 Circuits — Signal-Level FFC Interface
The SFV12R-2STE9HLF: It uses a top-contact, zero-insertion-force (ZIF) design with a slide lock actuator — the FFC slides in and the lock secures it without bending the pads.
Tin Contacts, 20 Mating Cycles — One-Time Assembly Fit
Tin-plated phosphor bronze contacts and a 20-cycle rating tell you this is a low-mate-duty connector — intended for connections made once during manufacture and rarely re-entered in the field. The 0.5 A per-contact current ceiling and 50 V rating confirm it carries signal, not power.
FFC Thickness and Cable End — Straight or Tapered, 0.30–0.33 mm
The slide lock actuator clamps the cable with a positive click; the housing material is glass-filled nylon rated UL94 V-0, halogen-free.
Peer Alternative — Gold Contacts vs Tin
The closest sibling is the SFV12R-2STAE1HLF: identical pitch, position count, height, and slide lock, but with gold contact finish instead of tin. If your application demands higher mating cycle life (gold supports 20+ cycles with less fretting), that part is the upgrade path — same footprint, same cable compatibility.
