Applications
The SFM-122-T2-L-D-A-K is designed for high-density board-to-board mezzanine interconnect applications in FPGA carrier boards, embedded SOM designs, and industrial I/O modules that require 44-position dual-row socket connectivity at 0.050" pitch. Its high-reliability construction supports demanding signal environments including high-frequency data buses and mixed analog-digital interfaces found in data acquisition systems and communications equipment. This surface-mount socket is also widely selected for test-and-measurement fixtures, medical diagnostic modules, and avionics ground-support electronics requiring compact, repeatable connector performance.

Frequently Asked Questions
How does the 44-position dual-row layout of SFM-122-T2-L-D-A-K serve high-density PCB signal routing?
The SFM-122-T2-L-D-A-K provides 44 signal positions arranged in 2 rows of 22 contacts at 0.050" (1.27 mm) pitch, fitting a board footprint of approximately 1.1" in length. Compared to a single-row 44-position connector at the same pitch, the dual-row layout reduces required board length by 50%, from approximately 2.1" to 1.1", making it ideal for compact embedded computing and SOM mezzanine designs.
Which FPGA and SOM board designs commonly use the SFM-122-T2-L-D-A-K for carrier-to-module connections?
FPGA mezzanine card (FMC) carrier boards, Xilinx Zynq SOM carrier designs, and Intel Cyclone module boards commonly use 44-position 0.050" socket strips like the SFM-122-T2-L-D-A-K for high-speed module-to-carrier interconnects. These designs require consistent impedance-matched connections supporting data rates from 500 Mbps to 3 Gbps per pin, which the high-reliability SFM-series socket provides through precision contact geometry and controlled PCB footprint spacing.
What stacking height options are available when mating SFM-122-T2-L-D-A-K with SAMTEC plug connectors?
When mated with SAMTEC SFM-series male plug connectors, the SFM-122-T2-L-D-A-K supports selectable board-to-board stacking heights typically ranging from 8 mm to 20 mm, depending on the specific plug variant chosen. A stacking height of 11 mm is a common selection for SOM carrier configurations providing clearance for components up to 8 mm tall on the module side, while 8 mm stacking suits ultra-low-profile mezzanine designs.
For a compact motor-drive control PCB, how does SFM-122-T2-L-D-A-K reduce total connector count compared to multiple smaller connectors?
For a motor-drive control board requiring 40 to 44 control and feedback signals, using a single SFM-122-T2-L-D-A-K 44-position socket consolidates all signals into one connector, occupying approximately 1.1" x 0.15" of board space. Using four 11-position connectors at the same pitch would require 4 separate footprints with 4 times the mating alignment complexity, and would typically increase connector assembly time by 3 to 4 minutes per board compared to single-connector placement.
