Frequently Asked Questions
What contact finish does the SQT-102-01-L-D use and how does it affect connector reliability?
The SQT-102-01-L-D uses Gold (10 µin) over Nickel (50 µin) on its mating contact surfaces. This gold finish provides excellent oxidation resistance and low, stable contact resistance, making the connector suitable for applications requiring high reliability and repeated mating cycles without signal degradation across all 4 positions.
What does the FLEXYZ Tiger Buy contact feature offer in the SQT-102-01-L-D?
The FLEXYZ Tiger Buy contact in the SQT-102-01-L-D provides a compliant, self-aligning socket contact design that accommodates minor misalignment during mating. This reduces insertion stress and improves mating reliability in automated assembly environments, maintaining consistent electrical performance across 4 dual-row positions with a body depth of 0.25 inch.
Which PCB assembly environments benefit most from the SQT-102-01-L-D's compact body dimensions?
Applications with tight PCB real estate benefit from the SQT-102-01-L-D's compact body measuring 0.17 inch in length, 0.158 inch in breadth, and 0.25 inch in depth. Industrial backplanes, embedded computing modules, and instrumentation daughterboards gain a low-profile 4-position dual-row socket interconnect without sacrificing the reliability of gold-plated contacts.
Is the SQT-102-01-L-D compliant with RoHS and lead-free requirements for international deployments?
Yes, the SQT-102-01-L-D is RoHS compliant and lead-free, as indicated by its Pb-free code. It meets current environmental regulations for the EU and other international markets, making it appropriate for consumer electronics, industrial control equipment, and communications hardware that must comply with hazardous substance restrictions across 4-position dual-row connector designs.
