Key Features
- 36-position dual-row socket strip with 0.050" (1.27 mm) pitch for medium-density SMT board-to-board connections
- T2 stacking height designation enables precise board-to-board standoff in mezzanine system designs
- LM tail length variant provides reliable solder joint formation in reflow assembly processes
- Gold-plated high-reliability contacts rated for extended mating cycles in demanding industrial and aerospace environments
Applications
The SFM-118-T2-LM-D-A-K is suited for medium-density board-to-board and mezzanine stacking applications in industrial computing, embedded systems, and telecommunications hardware. Its 36-position, 1.27 mm pitch surface-mount design makes it a practical choice for FPGA evaluation boards, interface daughter cards, and signal acquisition modules where reliable interconnects with controlled stack height are needed. The T2 stacking height option gives designers precise control over the board-to-board air gap, supporting thermal and mechanical clearance requirements.

Frequently Asked Questions
What pin count and pitch does the SFM-118-T2-LM-D-A-K offer, and how does that compare to 2.00 mm pitch connectors?
The SFM-118-T2-LM-D-A-K has 36 pins across 2 rows at a 0.050" (1.27 mm) pitch, which is roughly 57% denser than a 2.00 mm pitch dual-row connector of the same length. This allows more signals to be routed in a smaller PCB footprint for compact board-to-board applications.
What does the T2 designator specify for the SFM-118-T2-LM-D-A-K, and why does it matter in mezzanine designs?
The T2 designator specifies the stacking height, setting the precise board-to-board standoff distance when two PCBs are mated. In mezzanine system designs, this ensures adequate mechanical clearance and controlled air gap for thermal management, especially in multi-board enclosures with tight tolerances.
How is the SFM-118-T2-LM-D-A-K assembled onto a PCB, and is it compatible with standard reflow solder profiles?
The SFM-118-T2-LM-D-A-K uses surface-mount termination with an LM tail length, making it compatible with standard SMT reflow solder profiles. No through-hole drilling is required, and the 36-pin, 1.27 mm pitch layout is compatible with standard PCB pad patterns for pick-and-place automated assembly.
For which end applications is the SFM-118-T2-LM-D-A-K commonly selected over wire-to-board connectors?
Engineers select the SFM-118-T2-LM-D-A-K over wire-to-board connectors in applications like FPGA daughter cards, networking line cards, industrial automation modules, and avionics systems where a rigid 36-position, 1.27 mm pitch board-to-board interface is preferred for mechanical stability and consistent signal integrity across multiple mating cycles.
