Frequently Asked Questions
How does the 1.27 mm pitch of the SFM-124-T2-FM-D-A-K-TR benefit high-density PCB layouts?
The 1.27 mm (0.050") pitch allows 48 positions to be accommodated in roughly half the board space of a standard 2.54 mm pitch connector, making this socket strip suitable for compact FPGA daughter cards and mezzanine modules where PCB real estate is limited and signal count requirements remain high.
For which high-reliability application environments is the SFM-124-T2-FM-D-A-K-TR rated?
This socket strip is designed for high-reliability applications including aerospace, defense, and industrial instrumentation. The gold-plated contacts maintain less than 20 mΩ contact resistance over thousands of mating cycles, ensuring consistent electrical performance in environments subject to vibration and thermal cycling across -55°C to +125°C.
How does the SFM-124-T2-FM-D-A-K-TR compare to through-hole socket alternatives for mezzanine designs?
Compared to through-hole socket strips, the SFM-124-T2-FM-D-A-K-TR eliminates the need for 48 drilled holes per connector, reducing PCB fabrication cost and enabling double-sided component placement. Its 1.27 mm pitch SMT footprint also supports finer board routing channels, an advantage in high-speed signal designs above 100 MHz.
