Key Features
- 52-position dual-row socket configuration on 0.050" (1.27 mm) pitch delivers high signal density in minimal PCB footprint
- High-reliability gold-plated contacts provide low contact resistance and robust mating performance across extended cycle life
- Surface mount termination with T2 tail option enables controlled-depth soldering for consistent joint quality in automated assembly
Applications
The SFM-126-T2-F-D-A-K is suited for high-density board-to-board socket interconnects on FPGA daughter cards, embedded computing modules, and instrumentation systems requiring 52 fine-pitch signal channels. Its 0.050" pitch reduces PCB real estate compared to standard 0.100" connectors, enabling more compact designs. It is also used in communications daughtercards and industrial automation controllers that demand reliable signal integrity across dense socket arrays.

Frequently Asked Questions
How many positions and at what pitch does the SFM-126-T2-F-D-A-K provide signal connectivity?
The SFM-126-T2-F-D-A-K offers 52 total positions arranged in 2 rows of 26 contacts each at a 0.050" (1.27 mm) pitch, delivering high signal-count connectivity in approximately half the linear board space required by equivalent 0.100" pitch connectors.
For an FPGA mezzanine card design, what advantage does the SFM-126-T2-F-D-A-K socket offer over pin-header alternatives?
As a socket strip, the SFM-126-T2-F-D-A-K accepts mating pin headers with a female receptacle contact that can support multiple insertion cycles while maintaining contact resistance typically below 20 mΩ across all 52 positions, simplifying daughtercard swap and field serviceability in FPGA mezzanine applications.
What does the T2 designation in SFM-126-T2-F-D-A-K specify, and how does it influence soldering?
The T2 suffix in SFM-126-T2-F-D-A-K specifies the tail length of the SMT contact leads, typically around 0.20" depth, which controls solder joint volume across all 52 contacts during reflow and ensures consistent coplanarity for automated PCB assembly with standard paste-stencil print processes.
