What are the key features of SFM-134-L2-SM-D-A-K?
- 68 positions dual-row at 0.050" (1.27 mm) pitch enabling twice the signal density of standard 0.100" connectors
- Surface-mount termination compatible with automated SMT reflow assembly on both sides of the PCB
- High-reliability construction rated for demanding mating cycles in aerospace, defense, and telecom modules
- Low stack height profile reduces board-to-board clearance requirements in compact multi-board assemblies
What is SFM-134-L2-SM-D-A-K used for?
The SFM-134-L2-SM-D-A-K is used in high-density board stacking applications for military electronics, telecommunications switching modules, and industrial computing platforms requiring 68 reliable signal channels. Its 0.050" pitch dual-row layout supports compact daughter-card and mezzanine board designs where PCB area is limited. The SMT footprint allows placement alongside fine-pitch ICs on standard reflow assembly lines, simplifying manufacturing.

Frequently Asked Questions
What is the pin count and pitch of the SAMTEC SFM-134-L2-SM-D-A-K socket strip?
The SFM-134-L2-SM-D-A-K has 68 total positions in a dual-row layout with 0.050" (1.27 mm) pitch. Compared to 0.100" (2.54 mm) pitch alternatives, this fine pitch provides approximately 50% reduction in connector length for the same 68 circuits, saving board real estate in compact stack-up designs.
How does the high-reliability rating of the SFM-134-L2-SM-D-A-K differ from standard socket strips?
High-reliability SAMTEC socket strips are tested to higher mating cycle counts and more stringent contact resistance specifications than commercial-grade parts. This makes the SFM-134-L2-SM-D-A-K suitable for defense subsystems and telecom line cards where 68 signal contacts must maintain stable resistance over thousands of insertion cycles.
What assembly process does the SFM-134-L2-SM-D-A-K require for PCB mounting?
The connector uses surface-mount termination, making it compatible with standard SMT reflow soldering at typical peak temperatures of 245°C to 260°C. Automated pick-and-place machines can handle the 68-position body, enabling high-volume assembly alongside other SMT components without manual through-hole soldering operations.
Which board-to-board stacking applications benefit most from the SFM-134-L2-SM-D-A-K?
This socket strip suits mezzanine card, daughter-board, and FMC (FPGA Mezzanine Card) stacking designs where 68 signals at 1.27 mm pitch must be interconnected reliably. Defense avionics modules, telecom switching cards, and FPGA carrier boards are typical use cases requiring high-cycle-rated 0.050" pitch sockets.
