Key Features
- 48-position dual-row surface-mount configuration at 0.050-inch (1.27 mm) pitch for high-density board-to-board signal routing
- High-reliability socket strip construction with locking feature (K option) providing secure mating retention under vibration
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place assembly at volume production rates
Applications
The SFM-124-L2-LM-D-A-K-TR is used in high-density board-to-board and mezzanine connector applications where 48 signal contacts are required within a compact 0.050-inch pitch footprint. Its surface-mount design suits automated assembly lines in communications, computing, and test equipment platforms where reliable, repeatable interconnection is critical. Engineers also deploy it in module-on-board systems such as FPGA daughter cards and DSP expansion boards requiring robust mechanical retention.

Frequently Asked Questions
How does the 0.050-inch pitch of the SFM-124-L2-LM-D-A-K-TR benefit high-density FPGA expansion board layouts?
The 0.050-inch (1.27 mm) pitch allows 48 dual-row contacts to occupy a footprint under 65 mm in length, roughly half the board space of a 2.54 mm pitch alternative with the same pin count. This enables FPGA daughter cards to route high-speed signals between boards without compromising signal density or requiring multi-layer fanout vias.
What does the K option in SFM-124-L2-LM-D-A-K-TR indicate about its mating retention performance in vibration environments?
The K option designates a locking feature that mechanically secures the mated connector pair, preventing accidental unmating under vibration or shock loads. For industrial and aerospace test fixtures that experience continuous vibration above 5 G, this retention mechanism maintains contact integrity without additional hardware restraints.
Is the SFM-124-L2-LM-D-A-K-TR available in tape-and-reel for automated SMT assembly of 10,000-unit production runs?
Yes, the TR suffix confirms tape-and-reel packaging specifically for automated surface-mount pick-and-place equipment. A single reel typically holds several hundred to a few thousand pieces; purchasing through authorized distributors allows ordering in full-reel quantities compatible with standard SMT assembly lines handling 10,000-unit production volumes.
Which SAMTEC series is electrically compatible with SFM-124-L2-LM-D-A-K-TR to form a complete board-stacking solution?
SAMTEC's SFM series socket strips mate with corresponding SHF or TFM series header strips at the same 0.050-inch pitch, providing a matched 48-pin dual-row board-stacking solution with defined stack heights from 4 mm to over 12 mm. Designers should confirm the mating header's stack height and pin length to match the required PCB separation in their specific chassis design.
