Frequently Asked Questions

What pitch and contact arrangement does the SEAM-40-03.0-L-06-2-A-K-TR use?

The SEAM-40-03.0-L-06-2-A-K-TR uses a 0.050 inch (1.27 mm) pitch open-pin-field arrangement with 240 positions across a dual-row configuration, allowing flexible signal, power, and ground assignment on a 2.196 inch long connector body.

Which mating connector families are compatible with the SEAM-40-03.0-L-06-2-A-K-TR for board stacking?

This connector is compatible with SAMTEC SEARAY, SAMARRAY, and SEARRAY mating families, including Final Inch cable assemblies. The 3.0 mm stack height and gold-over-nickel contacts ensure stable mating engagement for high-cycle applications exceeding typical 30-insertion life requirements.

In which embedded computing or FPGA board designs is the SEAM-40-03.0-L-06-2-A-K-TR most suitable?

It is well suited for FPGA carrier boards, COM Express modules, and embedded computing platforms that require 240-pin board-to-board connectivity within a footprint of approximately 2.196 x 0.378 inches. The high-density 0.050 inch pitch supports multi-gigabit signal routing alongside 3.3 V and 5 V power rails in the same connector.

What surface finish does the SEAM-40-03.0-L-06-2-A-K-TR contact use, and why does it matter?

The contacts are finished with 10 µin gold over 50 µin nickel, which provides low and stable contact resistance, typically below 20 milliohms, making the connector reliable across temperature ranges of -55°C to +125°C in demanding signal-integrity applications.
