Key Features
- 40-position dual-row layout at 0.050" (1.27 mm) pitch enables high pin density in a compact SMD footprint
- High-profile (H) mating height option accommodates taller component clearance requirements in mezzanine stacking systems
- Gold-plated contacts deliver low contact resistance and long mating cycle reliability for high-reliability applications
- No tape-and-reel suffix indicates tray or tube packaging suited for prototype and lower-volume production runs
Applications
The SFM-120-L2-H-D-A-K is ideal for high-density mezzanine board-to-board connections in telecommunications switching equipment, FPGA evaluation platforms, and industrial embedded computing modules requiring 40 contacts at 0.050" pitch with a taller stacking clearance. The high-profile stack height variant provides additional room for through-hole components or heat sinks on the mated board, making it valuable in server blade and line-card designs with complex thermal management needs. Its gold-plated contacts and high-reliability construction support long service life in mission-critical interconnect applications.

Frequently Asked Questions
What does the 'H' designation in SFM-120-L2-H-D-A-K indicate about the connector's stack height?
The 'H' in the part number indicates a high-profile mating stack height, providing greater vertical clearance between stacked boards compared to standard or low-profile variants. This is particularly useful in 40-position, 0.050" pitch mezzanine assemblies where taller components, heat sinks, or additional PCB layers need clearance between the two mated boards.
How many positions per row does the SFM-120-L2-H-D-A-K provide in a dual-row configuration?
The SFM-120-L2-H-D-A-K has 40 total positions in a dual-row (D) format, meaning 20 pins per row spaced at 0.050" (1.27 mm) pitch. This delivers a high signal count in a compact surface-mount area, well-suited for FPGA daughter cards and data communications mezzanine boards with dense signal routing requirements.
For which system architectures is the SFM-120-L2-H-D-A-K most appropriate given its 0.050" pitch and 40-position count?
The SFM-120-L2-H-D-A-K is best matched to mezzanine systems such as blade servers, telecom line cards, and embedded computing modules requiring a 40-contact, 0.050" pitch high-profile surface-mount interface. The 1.27 mm pitch allows routing 40 signals in a PCB footprint roughly half the length required by a standard 0.100" pitch equivalent connector.
Is the SFM-120-L2-H-D-A-K available in tape-and-reel and what are the ordering considerations?
The SFM-120-L2-H-D-A-K without a TR suffix is typically supplied in tray or tube packaging, making it suitable for prototype builds and lower-volume SMT assembly. For high-volume automated production requiring tape-and-reel packaging of the 40-position, 0.050" pitch SAMTEC SFM series, the TR-suffixed variant SFM-120-L2-H-D-A-K-TR should be specified.
