Key Features
- 100-contact dual-row socket in 0.8mm pitch for high-density board-to-board stacking at 6.5mm height
- Gold (30µin) over nickel (50µin) contact plating for low contact resistance and extended mating cycles
- Polarization post prevents mis-mating during board assembly and field maintenance
- Tape-and-reel (TR) packaging enables high-volume automated SMT pick-and-place assembly
- RoHS-compliant construction meets global environmental and regulatory requirements
Applications
The SEAF-50-06.5-S-08-2-A-K-TR is designed for high-density board stacking applications in embedded computing, networking line cards, and modular instrumentation systems where a 6.5mm mezzanine height and 100 signal contacts are required. It pairs with Samtec SEAM or compatible plug connectors to create reliable inter-board signal and power paths in medical devices, industrial automation controllers, and communications equipment. The tape-and-reel format makes it well suited for high-volume SMT production lines.

Frequently Asked Questions
How many contacts does the SEAF-50-06.5-S-08-2-A-K-TR provide and at what pitch?
The SEAF-50-06.5-S-08-2-A-K-TR offers 100 contacts arranged in 2 rows of 50 positions each, at a 0.8mm pitch. This high-density layout enables transmission of 100 signals or mixed power-and-signal assignments across a compact board-to-board interface in embedded and modular PCB stacking designs.
What stacking height does this Samtec SEAF connector achieve between two PCBs?
This connector provides a 6.5mm board-to-board stacking height, creating a precise and repeatable 6.5mm gap between mated PCBs. The defined standoff allows predictable thermal management and routing of flex cables or power buses in the inter-board space of industrial controllers and communication modules.
When should designers choose the SEAF-50-06.5-S-08-2-A-K-TR over a lower-contact-count alternative?
Designers should select the 100-contact SEAF-50-06.5-S-08-2-A-K-TR when a single interface must carry 80 or more signal lines plus power, eliminating the need for two separate 50-pin connectors. Applications such as FPGA mezzanine cards, processor expansion modules, and DSP daughter boards benefit from the 100-pin capacity and 0.8mm pitch at a 6.5mm stack height.
Is the SEAF-50-06.5-S-08-2-A-K-TR suitable for automated SMT production?
Yes, the -TR suffix denotes tape-and-reel packaging with 1000 or 2000 units per reel depending on quantity, making it directly compatible with automated SMT pick-and-place equipment. The gold-plated contacts and standardized 0.8mm pitch footprint simplify solder paste printing and reflow processes in high-volume manufacturing environments.
