0.50 mm Pitch, 4-Position ZIF — Signal-Level FPC Interconnect
The SFV4R-2STE1HLF is a 4-position FFC/FPC connector on 0.50 mm pitch, using a zero-insertion-force (ZIF) top-contact design with a slide lock. The slide lock actuates the ZIF mechanism — the FPC inserts with zero force, then the lock slides to clamp the contacts against the flex pads.
Tin Contacts, 20 Cycles — Know the Reconnect Limit
For comparison, the sibling SFV4R-4STBE1HLF carries gold-plated contacts, which typically support 50+ cycles — a meaningful difference if the FPC is disconnected during test or calibration. The choice between tin and gold comes down to reconnect duty: tin for one-time build, gold for periodic access.
FPC Fit and Termination Checklist
The top-contact ZIF design means the flex circuit pads face upward toward the actuator — confirm the cable orientation before insertion. The right-angle SMT termination requires a reflow profile compatible with the PA housing material.
