Key Features
- 44-position dual-row layout at 0.050" (1.27 mm) pitch delivers 22 contacts per row for high-density signal interconnects in a compact SMT footprint
- High-reliability socket strip design with gold-plated contacts ensures low contact resistance and extended mating cycle life for board-to-board stacking applications
- Surface mount termination with tape and reel packaging supports automated pick-and-place assembly in high-volume PCB production lines
Applications
The SFM-122-L2-L-D-A-K-TR is used in FPGA mezzanine boards, server daughtercards, and industrial computing modules where 44 signals must be routed between stacked boards at a 1.27 mm pitch. Its dual-row SMT design minimizes board area compared to through-hole alternatives, making it suitable for space-constrained rack-mounted systems and ruggedized embedded computing platforms. The high-reliability gold contact finish meets the requirements of telecom and military-grade electronics that demand consistent signal integrity over thousands of mating cycles.

Frequently Asked Questions
How many positions and rows does the SFM-122-L2-L-D-A-K-TR provide, and what is the contact pitch?
The SFM-122-L2-L-D-A-K-TR offers 44 positions across 2 rows at a 0.050" (1.27 mm) pitch, providing 22 contacts per row. This dual-row arrangement on a 1.27 mm grid is widely used in high-density FPGA and processor mezzanine card standards, enabling compact board stacking with a large signal count in a small PCB area.
For a high-cycle mating application such as a test fixture socket, how does the SFM-122-L2-L-D-A-K-TR's contact design hold up?
SAMTEC's SFM series socket strips use gold-plated contacts engineered for high mating cycle count applications, maintaining low contact resistance over repeated insertions and removals. Gold plating resists oxidation and fretting corrosion, which is critical in test fixture sockets and instrumentation docking stations where the same board may be mated hundreds or thousands of times without noticeable degradation in signal integrity at 0.050" pitch.
Which procurement format is available for the SFM-122-L2-L-D-A-K-TR, and does it support automated assembly?
The SFM-122-L2-L-D-A-K-TR is supplied in tape and reel format, making it fully compatible with automated SMT pick-and-place machines and standard reflow soldering at peak temperatures up to 260°C. This packaging format reduces handling time and placement errors in volume production runs, which is cost-effective for FPGA daughter card and telecom line card assemblies that require precise 1.27 mm pitch component placement.
