Key Features
- 40-position single-row board stacking socket with 6.5 mm stack height and gold-plated mating contacts for reliable signal integrity across repeated mating cycles
- Integrated polarization post prevents mis-insertion in field-replaceable board assemblies, protecting all 40 signal positions from damage
- Tape-and-reel (TR) packaging compatible with automated SMT pick-and-place equipment, supporting high-volume assembly at throughputs of 1000+ parts per reel
Applications
The SEAF-40-06.5-S-10-1-A-K-TR is designed for high-density single-row board stacking applications in telecommunications line cards, industrial embedded modules, and FPGA mezzanine assemblies that require a reliable 40-pin interface at a 6.5 mm board-to-board standoff. The gold-plated socket contacts ensure low and stable contact resistance over hundreds of mating cycles, supporting both signal and low-power applications. The polarization post and keyed mechanical design make this connector ideal for field-replaceable module systems where error-free mating is critical to system uptime.

Frequently Asked Questions
What stack height and position count does the SEAF-40-06.5-S-10-1-A-K-TR provide for board-to-board assemblies?
The SEAF-40-06.5-S-10-1-A-K-TR provides 40 positions in a single-row socket configuration with a 6.5 mm board-to-board stack height, spanning a body length of approximately 56.6 mm (2.229 inches). Gold-plated contacts deliver contact resistance typically below 20 milliohms, supporting reliable signal transmission in dense board stacking applications across a wide operating temperature range.
How does the polarization post on SEAF-40-06.5-S-10-1-A-K-TR prevent field assembly errors?
The SEAF series polarization post is a mechanical feature that physically locks the connector into a single correct orientation relative to its mating header, making it impossible to insert the board rotated 180 degrees and protecting all 40 signal pins from damage or short-circuit conditions. This is especially valuable in field-serviceable telecom shelves and industrial control panels where technicians may replace boards under time pressure without detailed diagrams.
For which procurement scenarios does tape-and-reel packaging of SEAF-40-06.5-S-10-1-A-K-TR reduce total assembly cost?
When production volumes exceed 200 to 500 units per order, tape-and-reel packaging eliminates manual feeder loading and reduces pick-and-place machine changeover time compared to tube or tray formats, cutting per-unit assembly labor costs by a measurable margin. The TR suffix also ensures that the 40-position connector arrives on a standard reel compatible with 12 mm to 16 mm SMT feeders, simplifying supply chain qualification and allowing consistent automated placement of the 2.229-inch body length with sub-0.1 mm positional accuracy.
