Key Features
- 68-position dual-row socket strip at 0.050" (1.27 mm) pitch supporting high-density board edge and module mating in minimal PCB space
- Straddle-mount (STL) termination style allows the connector to mount on the PCB edge, enabling card-edge and vertical mating configurations
- Polarizing alignment peg (A) ensures precise positioning during automated SMT placement, preventing misalignment across 68 contacts
Applications
The SFM-134-T2-STL-D-A-P-TR is designed for high-density board edge interconnects in memory modules, FPGA development boards, and high-speed data acquisition systems requiring 68 positions at 0.050" pitch. Its straddle-mount design enables compact vertical mating at the PCB edge, reducing the board area consumed by connectors in space-constrained applications. The alignment peg and tape-and-reel packaging ensure consistent placement accuracy during high-volume automated SMT assembly.

Frequently Asked Questions
What does the straddle-mount (STL) termination mean for SFM-134-T2-STL-D-A-P-TR in a PCB edge application?
The straddle-mount (STL) termination on the SFM-134-T2-STL-D-A-P-TR means the connector straddles the edge of the PCB, with contacts soldering to pads on both sides of the board simultaneously. This allows the 68-position, 0.050" pitch socket to mount at the board perimeter for compact vertical mating with a pin header, reducing the overall footprint compared to a fully surface-mounted connector body placed away from the edge.
For a 68-signal high-speed interface between two PCBs, why choose SFM-134-T2-STL-D-A-P-TR at 0.050" pitch over a 0.100" pitch alternative?
At 0.050" (1.27 mm) pitch, the SFM-134-T2-STL-D-A-P-TR routes 68 signals in approximately half the board-edge length required by a 0.100" pitch connector, enabling more compact PCB design. This pitch is preferred in FPGA carrier boards and high-speed data acquisition modules where board real estate is at a premium and signal density requirements exceed what 0.100" pitch connectors can accommodate in the available space.
How does the alignment peg on SFM-134-T2-STL-D-A-P-TR improve manufacturing yield in automated SMT assembly?
The polarizing alignment peg (A suffix) on the SFM-134-T2-STL-D-A-P-TR mechanically locates the connector body precisely on the PCB pad pattern during pick-and-place, preventing rotation or lateral shift before reflow soldering. For a 68-position, 0.050" pitch component where each pad is just 1.27 mm from the next, even slight misalignment can cause solder bridging or open joints, so the peg is critical to achieving high first-pass yield in production.
