Key Features
- 68-position dual-row configuration at 0.050" (1.27 mm) pitch enables high-density large-scale board-to-board signal interconnect in minimal PCB footprint
- STL (straddle mount) termination style provides mechanical stability and improved coplanarity for reliable SMT reflow solder joints across all 68 contacts
- High-reliability stamped contacts with gold plating ensure low contact resistance and consistent mating performance over extended service life
- Compact 0.050" pitch dual-row layout reduces board space by up to 50% compared to equivalent 0.100" pitch 68-position connectors
Applications
The SFM-134-T2-STL-D-A-K is designed for high-pin-count board-to-board and daughter-card interconnect in embedded computing platforms, FPGA and DSP module interfaces, industrial automation backplanes, and test and measurement equipment requiring 68 signal positions at 0.050" pitch. Its straddle mount termination straddles the PCB edge, providing secure mechanical attachment for applications subject to vibration and mechanical stress. Engineers also specify it for high-density data acquisition systems and communication modules where routing 68 channels in a compact 0.050" pitch dual-row layout is essential.

Frequently Asked Questions
What does the STL (straddle mount) termination style mean for SFM-134-T2-STL-D-A-K installation?
The STL designation on SFM-134-T2-STL-D-A-K indicates a straddle mount termination, where the connector straddles the edge of the PCB and solders to pads on both the top and bottom surfaces. This dual-side attachment provides superior mechanical retention for the 68-position dual-row socket at 0.050" (1.27 mm) pitch, especially in applications subject to vibration or mechanical shock.
How does the 68-position count of SFM-134-T2-STL-D-A-K compare to smaller SFM variants for FPGA interface designs?
With 68 total positions (34 per row) at 0.050" (1.27 mm) pitch, the SFM-134-T2-STL-D-A-K can interface FPGA I/O banks or DSP module buses requiring 64 to 68 signal lines in a footprint approximately 43 mm long, providing a more space-efficient solution than two separate smaller dual-row connectors or a single 0.100" pitch 68-position alternative.
Which embedded computing and industrial applications benefit most from a 68-position 0.050" pitch socket like SFM-134-T2-STL-D-A-K?
High-pin-count embedded computing modules such as FPGA carrier boards, DSP daughter cards, and industrial automation controllers with 68-channel I/O backplanes benefit from the SFM-134-T2-STL-D-A-K. Its 0.050" (1.27 mm) pitch dual-row layout routes all 68 signals in roughly half the board length of a 0.100" pitch equivalent, which is critical in space-constrained rack-mount and embedded module designs.
What mating connector family is compatible with the SFM-134-T2-STL-D-A-K for a complete board-to-board assembly?
The SFM-134-T2-STL-D-A-K mates with SAMTEC TSM or SHF series 0.050" (1.27 mm) pitch dual-row headers with 68 positions. This mating pair provides a complete board-to-board interconnect solution rated for multiple insertion cycles, supporting signal buses up to 50 V AC/DC and approximately 1 A per contact in embedded and industrial system assemblies.
