Frequently Asked Questions
What pitch and contact finish does the SQT-110-01-L-D use for board-to-board mating?
The SQT-110-01-L-D uses a 2.00 mm pitch with gold (10 µin) over nickel (50 µin) contact plating, delivering low contact resistance and excellent corrosion resistance. This finish supports reliable mating in high-cycle-count applications typical of modular board-to-board interconnect systems.
How does the 6.65 mm row height of SQT-110-01-L-D affect PCB stacking design?
The 6.65 mm row height determines the standoff distance between mated PCBs in a stacking configuration, allowing clearance for components on the bottom board. Designers must account for this dimension alongside mating header height when calculating total stack-up thickness in embedded computing or industrial backplane assemblies.
In which applications is the SQT-110-01-L-D through-hole socket connector most commonly deployed?
This 2.00 mm pitch through-hole socket is commonly used in test and measurement instruments, embedded system modules, industrial automation controllers, and robotics boards where its 10-position dual-row configuration and mechanical retention through soldered pins provide reliable signal interconnection under vibration and thermal cycling.
What advantage does the FlexYZ TIGER BUY contact technology provide in the SQT-110-01-L-D?
FlexYZ contact technology provides enhanced lateral wiping action during mating, displacing surface contaminants and reducing contact resistance variability. This design benefit maintains signal integrity across the 10 positions per row in SQT-110-01-L-D, especially important in high-reliability applications requiring stable connections over thousands of mating cycles.
