Applications
The SFM-128-T2-L-D-A is ideal for high-density board-to-board and mezzanine interconnect applications in embedded computing, telecommunications equipment, and test-and-measurement systems. Its 56-position, 0.050-inch pitch surface-mount socket supports compact module stacking where space savings and reliable signal integrity across dozens of parallel lines are critical. It is also well-suited for industrial control boards and FPGA daughter-card interfaces requiring secure, repeatable mating.

Frequently Asked Questions
How many signal positions does the SFM-128-T2-L-D-A provide and how are they arranged?
The SFM-128-T2-L-D-A offers 56 total positions arranged in a dual-row format with 28 pins per row on a 0.050-inch (1.27 mm) pitch, providing high-density connectivity in a compact surface-mount footprint suitable for board-to-board applications.
For a mezzanine card design requiring 50+ signal lanes at 1.27 mm pitch, is the SFM-128-T2-L-D-A an appropriate choice?
Yes, the SFM-128-T2-L-D-A is designed exactly for this scenario, offering 56 positions at 0.050-inch (1.27 mm) pitch with a dual-row surface-mount socket rated for high-reliability mating cycles, making it suitable for mezzanine expansions in industrial and computing modules.
What is the contact pitch of the SFM-128-T2-L-D-A and how does it compare to standard 2.54 mm pitch connectors for PCB density?
The SFM-128-T2-L-D-A uses a 0.050-inch (1.27 mm) pitch, half the spacing of standard 2.54 mm pitch connectors, allowing approximately 4x more connection density per unit length and enabling 56 contacts in a footprint that a 2.54 mm-pitch strip would fill with only about 28 contacts.
Can the SFM-128-T2-L-D-A be placed using automated pick-and-place equipment for volume PCB manufacturing?
Yes, the SFM-128-T2-L-D-A is a surface-mount component compatible with automated pick-and-place assembly and reflow soldering, making it suitable for high-volume production with standard SMT equipment and minimizing manual assembly steps for its 56-position dual-row footprint.
