What are the key features of SFM-112-L2-STL-D-LC-TR?
- 24-position dual-row SMT socket strip on 0.050" (1.27 mm) pitch enabling high signal density in compact board footprints
- Long tail (STL) contact variant provides enhanced soldering standoff for reliable solder joint formation on SMT pads
- Low contact resistance gold-plated contacts rated for high reliability mating cycles in demanding environments
- Tape-and-reel (-TR) packaging supports automated pick-and-place SMT assembly for high-volume manufacturing
What is SFM-112-L2-STL-D-LC-TR used for?
The SFM-112-L2-STL-D-LC-TR is designed for high-density board-to-board and daughter-card interconnect applications in telecommunications, industrial automation, and embedded computing systems. Its 24-position dual-row layout and 0.050" pitch make it suitable for module-to-backplane interfaces where PCB real estate is limited. The long tail contact version provides increased soldering compliance, making it valuable in applications subject to mechanical stress or thermal cycling.

Frequently Asked Questions
How many positions and rows does the SFM-112-L2-STL-D-LC-TR provide, and what is its contact pitch?
The SFM-112-L2-STL-D-LC-TR provides 24 positions arranged in 2 rows with 12 contacts per row, on a 0.050" (1.27 mm) pitch. This dual-row configuration doubles the signal density compared to a single-row strip of the same footprint length, making it suitable for compact module interfaces requiring 24 signals in a minimal PCB area.
What does the STL designation mean for the SFM-112-L2-STL-D-LC-TR, and how does it affect soldering?
The STL designation in the SFM-112-L2-STL-D-LC-TR indicates a long tail contact length compared to the standard variant. This extended tail provides additional solder volume and compliance during reflow, helping to absorb thermal expansion mismatches between the connector and PCB. The longer tail contact is beneficial in applications where the assembly undergoes temperature cycling between -40°C and +85°C, reducing the risk of cracked solder joints.
For which board-to-board or daughter-card interface applications is the SFM-112-L2-STL-D-LC-TR best suited?
The SFM-112-L2-STL-D-LC-TR is optimally suited for daughter-card attachment in industrial control systems, FPGA mezzanine boards, and compact embedded modules where 24 signal lines must be routed through a 0.050" pitch interface. The high reliability construction supports applications requiring hundreds of mating cycles and stable contact resistance below 20 milliohms over the product lifetime.
What ordering and supply considerations apply when specifying the SFM-112-L2-STL-D-LC-TR for a production build?
The SFM-112-L2-STL-D-LC-TR ships in tape-and-reel format, ideal for automated SMT assembly lines running at high throughput. Samtec products are available from authorized distributors globally, and the SFM series typically supports custom lead times. For production volumes exceeding 1,000 pieces, buyers should confirm the reel quantity per standard Samtec packaging, which is usually 2,000 parts per reel for this pitch and position count.
