Frequently Asked Questions
How many contacts does the SFM-120-T2-SM-D provide and what pitch separates them?
The SFM-120-T2-SM-D provides 40 contacts in a dual-row arrangement on a 0.050" (1.27 mm) pitch. This fine pitch enables a high signal density within a body length of just 1.155 inches, making it an efficient choice for compact PCB-to-PCB interconnect designs in telecom and industrial boards.
What plating materials are used on the SFM-120-T2-SM-D contacts, and why does it matter for signal integrity?
The SFM-120-T2-SM-D uses gold-plated mating surfaces over a nickel barrier, combined with tin-over-nickel (Sn/Ni) solder terminations. Gold plating ensures low and stable contact resistance—typically under 20 milliohms—over thousands of mating cycles, which is critical for maintaining signal integrity in high-speed serial and parallel data bus applications.
Is the SFM-120-T2-SM-D verified lead-free for European RoHS compliance?
Yes, the SFM-120-T2-SM-D carries a Pb-free (lead-free) designation confirmed by its spec data. It is manufactured without restricted hazardous substances, meeting EU RoHS 2 Directive requirements and making it a compliant choice for equipment sold in European and other regulated international markets.
For a compact telecom line-card design, how does the SFM-120-T2-SM-D body size compare to higher-pitch alternatives?
The SFM-120-T2-SM-D body measures 1.155" long and 0.145" wide, which is roughly half the length of an equivalent 40-position connector on a 0.100" (2.54 mm) pitch. This space saving is significant in high-density telecom line-card designs where PCB real estate costs limit how many connectors can fit per board layer.
