28-Position, 0.50 mm Pitch, Top-Contact ZIF
The SFV28R-2STE1HLF: This is a 28-position FFC/FPC connector on 0.50 mm pitch, top-contact style — the cable's conductor pads face up when the actuator is open. The slide lock clamps the flex without insertion force, so the contact beams aren't stressed during cable insertion.
Cable Fit and Actuator Check
A flipped flex shorts the wrong row — confirm the conductor pattern matches top-contact orientation before closing the slide lock. The actuator is brown PPS, glass-filled and halogen-free; the housing is black LCP, glass-filled, halogen-free, rated UL94 V-0.
Mating Cycle Life and Field Service
In a product that ships pre-cabled and never opens in the field, the cycle count is adequate. For repeated cable swaps, look at the SFV-R series gold-plated variants.
Peer Comparison: SFV28R-2STE9HLF
The only functional difference between SFV28R-2STE1HLF and SFV28R-2STE9HLF is cable end type: this part accepts notched FPC tails; the -2STE9HLF accepts straight or tapered tails. All other specs — 28 positions, 0.50 mm pitch, top contact, tin finish, slide lock — are identical.
