What are the key features of SFM-123-T2-H-D-LC?
- 46-position dual-row socket at 0.050" (1.27 mm) pitch delivers high signal density in a compact SMT footprint half the size of 0.100" equivalents
- High-reliability contact system engineered for hundreds of mating cycles, supporting field-replaceable module designs
- Low-clearance (-LC) height profile minimizes board stack height, enabling ultra-thin multi-board assemblies in portable or space-constrained enclosures
What is SFM-123-T2-H-D-LC used for?
The SFM-123-T2-H-D-LC suits compact mezzanine card interconnects in embedded computing, medical imaging, and portable test instruments where minimizing PCB stack height is critical. Its 46-position dual-row layout at 0.050" pitch supports 46 simultaneous signal paths in a footprint smaller than a comparable 0.100" 24-position single-row connector. The low-clearance height option makes it a natural fit for slim industrial handheld devices and wearable electronics platforms.

Frequently Asked Questions
What does the -LC suffix mean for the SFM-123-T2-H-D-LC, and how does it affect PCB stack height?
The -LC suffix denotes a low-clearance height variant that reduces the mated stack height compared to standard SFM profiles, typically bringing the total board separation down to approximately 4 mm or less. This is critical in slim enclosures such as portable medical devices or handheld instruments where every millimeter of board stack-up matters.
For a 46-signal interface on a compact PCB, why choose the SFM-123-T2-H-D-LC over a standard 0.100" dual-row socket?
The SFM-123-T2-H-D-LC operates at 0.050" (1.27 mm) pitch, so its 46-position dual-row footprint occupies roughly half the PCB area of an equivalent 0.100" connector. This space saving is decisive in designs where the connector zone is constrained to under 30 mm of board length, such as compact FPGAs or SOM carrier boards.
How many mating cycles can the SFM-123-T2-H-D-LC withstand, and what does that mean for serviceability planning?
SAMTEC SFM-series high-reliability socket strips are rated for hundreds of mating cycles, often 500 or more, meaning a module plugged and unplugged once per week could remain in service for approximately 10 years before contact wear becomes a concern. This cycle life supports modular architectures where 46-signal daughter cards are swapped during field maintenance or system upgrades.
