What are the key features of SFM-104-T2-LM-D-A-P?
- 8-position dual-row socket at 0.050" (1.27 mm) pitch in a minimal SMT footprint, ideal for SOM and mezzanine module interfaces
- Alignment post (-A) and polarization (-P) features ensure correct orientation during reflow soldering and mating, preventing pin damage
- Low-mated-height (-LM) profile minimizes board-to-board stack gap, enabling ultra-compact multi-board assemblies in portable electronics
What is SFM-104-T2-LM-D-A-P used for?
The SFM-104-T2-LM-D-A-P is designed for compact system-on-module (SOM) and mezzanine card connections in portable medical devices, wearable electronics, and miniaturized IoT sensor nodes. Its 8-position dual-row layout at 0.050" pitch carries up to 8 signals in a footprint under 6 mm wide, enabling very dense multi-board stacking. The low mated height and built-in alignment post make it reliable in vibration-prone or field-deployed enclosures where mechanical precision is essential.

Frequently Asked Questions
What does the -LM suffix mean on SFM-104-T2-LM-D-A-P, and what board-to-board clearance does it provide?
The -LM suffix indicates a low-mated-height design that reduces the gap between mated PCBs compared to the standard SFM profile. The low-mated-height variant typically achieves a board-to-board clearance of approximately 4 mm or less, which is critical in slim device enclosures such as wearable health monitors or handheld scanners where total assembly thickness must stay under 10 mm.
For an 8-signal SOM interface, why choose a 0.050" pitch connector like SFM-104-T2-LM-D-A-P over a standard 0.100" option?
At 0.050" (1.27 mm) pitch, the SFM-104-T2-LM-D-A-P occupies a contact span of roughly 5 mm for 4 positions per row, compared to approximately 10 mm for a 0.100" equivalent. This 2x footprint reduction matters significantly on SOM carrier boards where multiple connectors compete for edge space, and where keeping each connector under 6 mm preserves routing channels for high-speed signals.
How do the -A (alignment post) and -P (polarization) features of this SAMTEC socket strip reduce assembly defect rates?
The -A alignment post locates the socket within 0.1 mm on the PCB pad before and during reflow, preventing the connector from floating out of position in the liquid-solder phase. The -P polarization feature physically blocks incorrect 180-degree insertion, eliminating pin-reversal damage on an 8-pin dual-row interface where all contacts would otherwise be shorted to wrong nets.
