What is SFM-120-T2-H-D used for?
SFM-120-T2-H-D is used in high-density board-to-board socket interconnects for defense electronics, medical instrumentation, and high-speed data acquisition systems where a 0.050 inch pitch enables more signals in a smaller footprint. The gold contact finish and high-reliability construction ensure stable electrical performance across extended operating life and repeated mating cycles. Its surface mount footprint of 1.155 inch body length allows designers to integrate 40-pin connectivity in space-constrained PCB areas typical of compact embedded computing and RF modules.

Frequently Asked Questions
Why choose a 0.050 inch pitch connector like SFM-120-T2-H-D over a standard 0.100 inch pitch alternative?
At 0.050 inch (1.27 mm) pitch, SFM-120-T2-H-D delivers 40 contacts in a body length of just 1.155 inches, roughly half the board space of an equivalent 0.100 inch pitch connector. This density advantage is critical in defense electronics, medical devices, and compact embedded modules where PCB real estate is scarce and routing 40 signals in a minimal footprint is a design priority.
What is the gold contact thickness on SFM-120-T2-H-D and how does it affect connector lifespan?
SFM-120-T2-H-D uses a 30 microinch gold mating finish over a nickel barrier on all 40 contacts. Thicker gold plating reduces oxidation and maintains low contact resistance over hundreds or thousands of mating cycles, making this socket strip particularly well-suited for high-reliability applications in medical instrumentation and aerospace systems where connector failure is not acceptable.
Is SFM-120-T2-H-D compatible with automated SMT pick-and-place assembly for high-volume production?
Yes. SFM-120-T2-H-D uses surface mount termination compatible with standard SMT pick-and-place machines and reflow ovens. The 40-position dual-row body can be placed and soldered alongside other SMT components in a single reflow pass, reducing assembly steps and cost compared to through-hole alternatives for 0.050 inch pitch socket connectors in production volumes.
How does the YTEOL rating of 9.4 years benefit long-lifecycle embedded system designs?
A YTEOL (Years to End of Life) of 9.4 indicates SFM-120-T2-H-D is projected to remain in active production for approximately 9 more years. Defense, medical, and industrial embedded systems often carry 7- to 10-year production lifecycles, so this YTEOL rating gives engineering teams confidence that this 40-position, 0.050 inch pitch socket connector will remain available through the full product manufacturing run without requiring a costly connector redesign.
