Frequently Asked Questions
How many positions does the SFM-140-T2-F-D-A-K-TR provide and what is its pitch?
The SFM-140-T2-F-D-A-K-TR is an 80-position dual-row socket strip with a 0.050" (1.27 mm) pitch, making it suitable for high-density surface-mount interconnect applications where board space is limited.
What contact finish is used on the SFM-140-T2-F-D-A-K-TR mating interface and why does it matter?
The mating contacts feature gold flash (3 micro-inch minimum) over a nickel barrier, while termination contacts use tin (Sn) finish. Gold flash provides corrosion resistance and reliable low-resistance connections across hundreds of mating cycles in industrial and telecom environments.
Which applications benefit most from using the SFM-140-T2-F-D-A-K-TR in a board-to-board configuration?
Applications requiring 80 pins of dual-row connectivity in a compact 2.075" body length include communication backplanes, defense electronics, and test equipment. The 0.050" pitch and surface-mount termination support high-speed signal routing at board spacings as low as 0.185" stack height.
How does the Tiger Eye contact design in the SFM-140-T2-F-D-A-K-TR improve reliability compared to standard socket contacts?
Tiger Eye contacts generate higher normal force over a longer contact wipe distance compared to standard bifurcated contacts, maintaining reliable electrical connection even with slight misalignment or vibration. This contact geometry supports a minimum of 30 mating cycles at contact resistance below 20 milliohms.
