Applications
The SFM-126-T2-S-D-A-K is designed for high-density signal connections between PCBs or between a board and a mezzanine module, providing 52 contacts at 1.27 mm pitch in a compact short-tail SMT socket. It is commonly used in embedded computing platforms, FPGA development systems, and modular telecommunications equipment where reliable high-cycle-life mating of 52-position dual-row sockets is required. The surface-mount format supports standard automated reflow assembly processes.

Frequently Asked Questions
What does the short tail (S) contact style on SFM-126-T2-S-D-A-K offer compared to standard tail lengths?
The short tail (S) designation on SFM-126-T2-S-D-A-K reduces the overall protrusion of contact tails below the PCB, which lowers the component's total mounted height. For 52-position dual-row sockets at 0.050 inch (1.27 mm) pitch, shorter tails are important in stacked-board configurations where clearance between PCB layers is limited to a few millimeters.
How does SFM-126-T2-S-D-A-K serve applications requiring more than 38 but fewer than 100 signal connections?
With 52 positions at 0.050 inch (1.27 mm) pitch, SFM-126-T2-S-D-A-K fills the mid-range between smaller 38-position SFM-119 variants and larger 100-position SFM-150 strips. This makes it appropriate for interfaces requiring 52 signals — such as 48-bit data buses plus control lines, or combined power and signal connections — in embedded boards, FPGAs, and modular computing modules.
Which assembly process is SFM-126-T2-S-D-A-K optimized for, and what are the production implications?
SFM-126-T2-S-D-A-K is a surface-mount component optimized for automated SMT reflow soldering. Its 52 positions at 1.27 mm pitch are arranged on an SMT footprint compatible with standard stencil printing and pick-and-place equipment, allowing consistent, repeatable placement at production scale without requiring manual through-hole assembly or selective soldering steps.
