Frequently Asked Questions
What stack height does SEAM-20-07.0-S-04-2-A-K-TR provide for board-to-board assemblies?
The SEAM-20-07.0-S-04-2-A-K-TR provides a 7.0 mm stack height, making it suitable for mezzanine board designs where a specific board-to-board separation is required. This 20-position, 4-row stacking connector also supports PEG board mounting for added mechanical stability in vibration-prone environments.
What contact finish does SEAM-20-07.0-S-04-2-A-K-TR use and why does it matter for high-cycle applications?
The connector uses Gold (30 µin) over Nickel (50 µin) contact plating, delivering low contact resistance and resistance to oxidation over many mating cycles. This finish is particularly important in high-reliability applications such as test equipment, defense electronics, and industrial control systems requiring durable signal integrity across 20 positions.
When should an engineer choose SEAM-20-07.0-S-04-2-A-K-TR over a shorter-stack equivalent?
The 7.0 mm stack height of SEAM-20-07.0-S-04-2-A-K-TR is ideal when designs require board clearance for tall components such as capacitors exceeding 5 mm height, or when thermal management hardware is mounted between stacked boards. Its 4-row, 20-position layout also allows up to 80 contacts within a compact body length of 1.196 inches.
