Frequently Asked Questions
What stack height does the SEAF-40-05.0-L-10-2-A-K-TR provide for board-to-board spacing?
The SEAF-40-05.0-L-10-2-A-K-TR provides a 5.0 mm stack height, allowing precise 5.0 mm separation between two parallel PCBs in a stacking configuration. This dimension is critical for space management in multi-board assemblies with 40 signal positions.
How does the gold contact finish on SEAF-40-05.0-L-10-2-A-K-TR benefit long-term connector reliability?
Gold-plated mating contacts deliver low and stable contact resistance, typically below 20 milliohms, even after hundreds of mating cycles. The gold finish resists oxidation and corrosion, ensuring signal integrity across 40 positions in industrial and telecom applications operating over a wide temperature range.
Which embedded computing designs benefit from using SAMTEC SEAF-40-05.0-L-10-2-A-K-TR instead of a single-board solution?
Modular embedded systems, FPGA daughtercard assemblies, and industrial I/O expansion boards benefit from this 40-position, 5.0 mm stack height connector. It enables a clean 40-signal interface between a main carrier board and a mezzanine module, reducing board complexity while keeping the stacked PCB separation at exactly 5.0 mm.
