Current, Voltage, and Contact Duty
The SFV18R-2STE1HLF: The 0.50 mm pitch limits per-contact current before the housing temperature rise becomes a factor; do not use for power distribution. Tin-plated phosphor bronze contacts are cost-optimised for low-cycle, indoor applications. With 20 mating cycles rated, this connector is designed for one-time assembly or infrequent field disconnect — not daily reconnection.
Top-Contact Orientation and ZIF Actuation
Top-contact configuration means the FPC pads face upward when the flip-lock actuator is open. This is a common mis-seat trap — confirm the ribbon orientation before closing the lock. Zero Insertion Force (ZIF) with a flip-lock actuator: the actuator lifts the contact beam away from the FPC pad during insertion, then clamps down. No insertion force on the ribbon, but the actuator must be fully closed to make contact.
Material and Environmental Range
The actuator is polyphenylene sulfide (PPS), also glass-filled and halogen-free. RoHS compliant — no restricted substances per the current directive.
Selecting Between SFV18R Siblings
The closest alternative is SFV18R-1STE1HLF — identical in every spec except contact orientation: that part is bottom-contact, meaning the FPC pads face downward when the actuator is open. If your FPC tail is routed with pads on the opposite side, swap to the -1 variant.
