Frequently Asked Questions
What contact finish does the SMS-120-01-L-D use, and why does it matter for connector reliability?
The SMS-120-01-L-D uses gold (10 µin) over nickel (50 µin) on mating contacts, which provides low and stable contact resistance, excellent corrosion resistance, and a long mating life. The tin-over-nickel solder termination finish ensures reliable reflow solder joints on the PCB side, suitable for standard SMT assembly processes.
How does the SMS-120-01-L-D's 1.27 mm pitch compare to 2.00 mm pitch connectors in terms of board space savings?
The SMS-120-01-L-D uses a 0.050" (1.27 mm) pitch, which is approximately 36% finer than a 2.00 mm pitch connector. For a 40-position dual-row interface, this finer pitch results in a significantly shorter connector body, freeing board real estate in compact embedded designs and high-density PCB layouts.
Is the SMS-120-01-L-D compatible with RoHS regulations, and what does that mean for procurement?
Yes, the SMS-120-01-L-D is RoHS compliant, meaning it is manufactured without restricted hazardous substances such as lead, mercury, and cadmium. This makes it directly usable in products exported to the EU and other markets with environmental regulations on electronic assemblies, simplifying global procurement and compliance documentation.
For which electronic system types is the SMS-120-01-L-D most commonly specified?
The SMS-120-01-L-D is most commonly specified in networking line cards, embedded computing modules, telecommunications shelf hardware, FPGA-based development platforms, and industrial automation systems where a 40-position, 1.27 mm pitch dual-row SMT socket provides reliable high-density board-to-board signal routing in a compact package.
