What are the key features of SFM-123-L2-LM-D-LC?
- 46-position dual-row socket at 0.050" (1.27 mm) pitch providing 23 contacts per row for high-density SMT board interconnects
- Low-profile LM mating height variant reducing overall assembly stack height in space-constrained enclosures
- High-reliability SFM series construction qualified for industrial, telecommunications, and defense board applications
What is SFM-123-L2-LM-D-LC used for?
The SFM-123-L2-LM-D-LC is designed for mezzanine board-to-board interconnect in telecommunications infrastructure, embedded computing, and data acquisition systems. Its 46-position dual-row layout at 0.050" pitch delivers high signal density while minimizing PCB real estate. The low-profile mating height variant is particularly valued in thin enclosures and stacked module designs where vertical clearance is constrained.

Frequently Asked Questions
How many positions and what pitch does the SFM-123-L2-LM-D-LC support for SMT board interconnects?
The SFM-123-L2-LM-D-LC provides 46 positions in a dual-row configuration at 0.050" (1.27 mm) pitch, offering 23 contacts per row. This high pin density enables compact mezzanine board-to-board connections for signal routing in data communications, embedded computing, and instrumentation designs.
What does the LM suffix mean in the SFM-123-L2-LM-D-LC part number, and why does it matter for system design?
The LM suffix denotes a low-profile mating height variant in Samtec's SFM series. For system designs where two PCBs are stacked in tight enclosures with limited vertical clearance, the LM mating height reduces the overall stack height compared to standard height variants, allowing board stacking in thin chassis and compact embedded modules.
Can the SFM-123-L2-LM-D-LC be assembled using standard reflow soldering, and what volume applications benefit most?
Yes, the surface-mount (SM) termination of the SFM-123-L2-LM-D-LC is fully compatible with standard SMT reflow soldering at typical profiles up to 260°C. High-volume production of networking equipment, FPGA mezzanine cards, and test instrumentation benefit most, as the SMT footprint enables automated pick-and-place and consistent 46-pin solder joint formation across large PCB runs.
