Frequently Asked Questions

What is the stack height and contact count of the SEAM-50-11.0-S-04-2-A-K-TR?

The SEAM-50-11.0-S-04-2-A-K-TR features a 11.0mm stack height with 50 positions (contacts), making it ideal for board-to-board stacking applications requiring a specific 11mm PCB separation distance. The connector body measures approximately 2.696 inches in length.

What contact plating does the SEAM-50-11.0-S-04-2-A-K-TR use and why does it matter for signal integrity?

The mating contacts feature gold (30 microinches) over nickel (50 microinches) plating, which provides excellent corrosion resistance and low contact resistance across 500 or more mating cycles. The termination side uses tin over nickel barrier plating for reliable solder joint formation on PCB pads.

Which board stacking applications are best suited for the SEAM-50-11.0-S-04-2-A-K-TR with its 11.0mm height?

This connector is best suited for server daughter card assemblies, telecom line cards, and industrial computing boards requiring exactly 11.0mm PCB-to-PCB spacing. The 50-position configuration supports mixed signal and power distribution across 2 rows, and the peg board mounting option adds mechanical retention strength in vibration-prone environments.

Is SEAM-50-11.0-S-04-2-A-K-TR RoHS compliant and does it support lead-free assembly processes?

Yes, the SEAM-50-11.0-S-04-2-A-K-TR is fully RoHS compliant and lead-free (Pb-free), with tin-based termination finish compatible with standard 260°C peak reflow soldering processes used in lead-free SMT assembly lines.
