Frequently Asked Questions
What stack height and contact finish does SEAF-40-06.5-S-08-2-A-K-TR provide for board stacking designs?
The SEAF-40-06.5-S-08-2-A-K-TR offers a 6.5 mm board-to-board stack height with Gold (30 µin) over Nickel (50 µin) mating contact finish. The 30 µin gold plating provides excellent wear resistance, making it suitable for applications where boards are connected and disconnected repeatedly during testing or field servicing.
How does the polarization post feature on SEAF-40-06.5-S-08-2-A-K-TR prevent assembly errors in production?
The polarization post on the SEAF-40-06.5-S-08-2-A-K-TR physically prevents incorrect board orientation during mating by adding a keying element that only aligns with the matching header in the correct position. This reduces the risk of reversed insertion, which can cause permanent damage to signal traces or components on both mating boards.
What are the physical dimensions of SEAF-40-06.5-S-08-2-A-K-TR and how do they affect PCB layout planning?
The connector body measures 2.229 inch in length, 0.421 inch in breadth, and 0.258 inch in depth. These dimensions must be accounted for in PCB keep-out zones and component placement rules. The 40-position single-row layout along 2.229 inch allows signal routing on both sides of the connector body without interference in typical 8-layer board designs.
