Frequently Asked Questions
What does the STL (straddle-mount) designation mean for the SFM-147-T2-STL-D-A?
The STL designation indicates a straddle-mount configuration, meaning the connector mounts directly to the PCB edge by straddling it from both sides. This provides a mechanical advantage by distributing mating forces along the 94-position, 0.050" pitch dual-row layout, eliminating the need for a separate edge-card socket and reducing assembly height by up to several millimeters compared to standard vertical board connectors.
How many signal positions does SFM-147-T2-STL-D-A support, and what board area does it occupy?
The SFM-147-T2-STL-D-A provides 94 positions in a dual-row layout at 0.050" (1.27 mm) pitch. The total connector length across 47 positions per row at 1.27 mm spacing is approximately 59.7 mm, offering very high signal density in a compact footprint suited for FPGA boards, mezzanine cards, and dense telecom modules where space efficiency is critical.
When is SFM-147-T2-STL-D-A preferred over a standard vertical SMT socket for edge-card applications?
The SFM-147-T2-STL-D-A is preferred when the PCB design calls for direct edge-card mating without an intermediate daughtercard connector. Its straddle-mount design allows plug-in module insertion at the board edge, which reduces connector stack height by eliminating a mating half, supports 94-signal throughput at 1.27 mm pitch, and simplifies field replacement of mezzanine modules in telecom, networking, and embedded computing platforms.
