Frequently Asked Questions
What stack height and pin count does the SEAM-20-07.0-L-04-2-A-K-TR provide for board stacking?
The SEAM-20-07.0-L-04-2-A-K-TR provides a 7.00 mm board-to-board stack height with 40 positions in a dual-row configuration. This precisely controlled stack height is critical for multi-board system designs in industrial computing and telecommunications, ensuring consistent mechanical alignment and signal integrity across 40 channels.
How does the gold-over-nickel contact finish on the SEAM-20-07.0-L-04-2-A-K-TR benefit high-reliability applications?
The connector uses 10 µin gold plated over 50 µin nickel for its mating contacts, providing contact resistance typically under 20 milliohms while resisting oxidation and corrosion over thousands of mating cycles. This contact finish is essential for defense, aerospace, and medical equipment operating across wide temperature ranges of -55°C to +125°C.
When should an engineer choose the SEAM-20-07.0-L-04-2-A-K-TR over a shorter-stack board connector?
The 7.00 mm stack height of this SAMTEC SEAM series connector is selected when component clearance between stacked PCBs exceeds 5 mm, such as when heat sinks, tall capacitors, or shielding cans occupy the inter-board space. The 40-position dual-row layout provides sufficient signal channels for embedded processor boards with 32 data lines plus 8 control signals, supporting applications where shorter stack heights would cause mechanical interference.
