Applications
The SFM-134-02-S-D-A-K supports high-density mezzanine interconnects in data communications equipment, FPGA-based processing boards, and high-channel-count instrumentation systems. With 68 positions at 0.050" pitch, it enables simultaneous routing of wide parallel data buses and analog signal channels on compact two-board stacks. Defense electronics and avionics platforms also utilize this connector where reliable 68-pin connections in a minimal footprint are required.

Frequently Asked Questions
How does the 68-position count of SFM-134-02-S-D-A-K support wide data bus designs?
With 68 total positions in a dual-row 0.050" pitch arrangement, the SFM-134-02-S-D-A-K can carry a 32-bit data bus plus 36 additional lines for address, control, power, and ground signals simultaneously. This eliminates the need for multiple smaller connectors, reducing board complexity and improving signal integrity for parallel bus architectures running at up to several hundred MHz.
What mounting style does the S suffix in SFM-134-02-S-D-A-K indicate, and how does it affect PCB layout?
The S suffix denotes a straight SMT tail termination, where solder tails extend vertically downward into standard SMT pads at 0.050" pitch. This style provides a consistent 0.050" center-to-center pad spacing across all 68 positions, making it straightforward to route on a PCB with standard 0.1 mm minimum trace clearance and compatible with Samtec's standard footprint recommendations.
In which applications is SFM-134-02-S-D-A-K preferred over a 0.100" pitch 68-position connector?
The SFM-134-02-S-D-A-K at 0.050" pitch occupies roughly half the linear board length of a 0.100" pitch 68-pin connector, making it essential in designs where mezzanine board length is constrained to under 50 mm. Server blade compute modules, compact FPGA carrier boards, and ruggedized avionics line-replaceable units (LRUs) all benefit from this size reduction while maintaining the same 68 signal connections.
