What are the key features of SFM-113-T2-FM-D-LC-TR?
- 26-position dual-row layout at 0.050" (1.27 mm) pitch with friction-mate (FM) contact system for tool-free, low-insertion-force mating
- Extended T2 solder tail improves solder joint stand-off and fillet formation on fine-pitch 1.27 mm SMT pads
- High-reliability contact construction maintains signal integrity across thousands of mating cycles in demanding environments
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for high-volume PCB production
What is SFM-113-T2-FM-D-LC-TR used for?
The SFM-113-T2-FM-D-LC-TR is used in FPGA daughter cards, mezzanine board interfaces, and module-to-baseboard designs requiring a 26-signal low-insertion-force connector at 1.27 mm pitch. Its friction-mate contact system allows boards to be connected and disconnected with minimal force, making it ideal for test fixture sockets and field-replaceable computing modules. The extended solder tail and tape-and-reel format ensure quality solder joints and seamless integration into automated SMT production lines.

Frequently Asked Questions
What does the FM (friction-mate) contact designation mean for the SFM-113-T2-FM-D-LC-TR?
The FM designation indicates that the SFM-113-T2-FM-D-LC-TR uses a friction-mate contact system, which requires lower insertion force than standard wiping contact designs. Across all 26 dual-row positions at 1.27 mm pitch, this reduces the cumulative mating force needed, making the connector easier to mate by hand in test fixtures, field-replaceable modules, and applications where a PCB press is not available.
How does the T2 extended solder tail improve reliability for the SFM-113-T2-FM-D-LC-TR in production?
The T2 extended tail on the SFM-113-T2-FM-D-LC-TR provides a longer termination length at each of the 26 dual-row positions, increasing solder paste volume and joint stand-off height on the 1.27 mm pitch SMT pads. This reduces the incidence of insufficient solder joints during reflow, and the taller fillet is more readily detected by automated optical inspection (AOI) equipment, lowering escape rates in high-volume production.
In what scenario would an engineer select the SFM-113-T2-FM-D-LC-TR over a standard-force SFM variant for a 26-position interface?
An engineer would choose the FM variant when the 26-position connector must be mated and unmated repeatedly without tools, such as in a test socket where boards are inserted and removed during functional testing. The lower mating force also reduces the risk of mechanical damage to fine-pitch 1.27 mm pitch pads and adjacent surface mount components when boards are connected by hand rather than guided by a mechanical jig or press fixture.
