- Polarization post (K option) prevents mis-mating during assembly, reducing rework risk in high-density 50-pair stacking connector installations
- RoHS-compliant gold-contact socket in tape-and-reel packaging supports automated SMT assembly and meets global environmental compliance requirements
Applications
The SEAF-50-06.5-S-10-2-A-K-TR is designed for high-density board stacking applications in telecommunications line cards, FPGA mezzanine modules, and embedded computing platforms. Its 100-position, 1.27 mm pitch layout with a fixed 6.5 mm stack height accommodates multi-board system architectures where precise vertical spacing is critical. The polarization post and tape-and-reel format streamline automated assembly and eliminate connector orientation errors in production environments.

Frequently Asked Questions
What stack height and pin count does the SEAF-50-06.5-S-10-2-A-K-TR provide for board stacking designs?
The SEAF-50-06.5-S-10-2-A-K-TR provides a 6.5 mm stack height with 100 positions (50 pairs) arranged in 2 rows at 1.27 mm pitch, making it suitable for mezzanine board stacking systems requiring a fixed vertical separation between PCBs.
How does the polarization post option (K) help during PCB assembly of this Samtec stacking connector?
The -K polarization post physically prevents a 180-degree mis-mating with the complementary plug, avoiding costly rework in automated assembly lines where 100-position, 1.27 mm pitch connectors could otherwise be installed in the wrong orientation, especially given the body length of 2.729 inches.
Which mezzanine or FPGA module applications are best served by this board stacking socket?
This 100-position, 6.5 mm stack height socket is well matched to FPGA daughter card interfaces, telecom FMC mezzanine modules, and industrial SBC expansion boards that require reliable high-density signal routing between two PCBs separated by a defined 6.5 mm gap across an operating temperature range of -55°C to +125°C.
Is the SEAF-50-06.5-S-10-2-A-K-TR compatible with automated pick-and-place assembly?
Yes, the -TR suffix denotes tape-and-reel packaging, enabling standard pick-and-place equipment to handle this 100-position stacking connector at 1.27 mm pitch; the gold-plated contacts and RoHS compliance further facilitate use in high-volume production environments worldwide.
