Frequently Asked Questions
What is the mating stack height of the SEAF-40-05.0-S-06-1-A-K-TR connector?
The SEAF-40-05.0-S-06-1-A-K-TR provides a 5.00 mm board-to-board stack height, making it suitable for compact mezzanine card assemblies where vertical spacing between PCBs must be tightly controlled within space-constrained enclosures.
What contact finish does the SEAF-40-05.0-S-06-1-A-K-TR use on its mating interface?
The mating contacts feature gold (30 µin minimum) over nickel (50 µin minimum) plating, delivering low contact resistance and excellent corrosion resistance. The termination side uses tin over a nickel barrier, compatible with standard reflow soldering at temperatures up to 260°C.
In which application domains is the SEAF-40-05.0-S-06-1-A-K-TR commonly used?
This 40-pin stacking connector suits industrial control systems, telecom line cards, and embedded computing modules that stack daughter cards. The gold-plated 40-position interface supports reliable signal and power transfer across boards separated by 5.00 mm in rack-mount or panel-mount enclosures.
How does the SEAF-40-05.0-S-06-1-A-K-TR compare to other stack heights in the SEAF series?
The SEAF series is available in multiple stack heights; the -05.0- variant provides 5.00 mm spacing, whereas shorter heights like 3.00 mm or taller heights like 10.00 mm address different board clearance needs. Selecting 5.00 mm allows routing of components up to approximately 4 mm tall on the bottom board within the 40-pin footprint.
