Key Features
- Tiger Eye contact design with beryllium copper spring material delivering superior normal force and extended mating cycle life up to tens of thousands of cycles
- 10 µin (0.25 µm) gold mating finish on contacts ensuring minimal contact resistance and reliable signal integrity over thousands of mating cycles
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place assembly at high production volumes with 1-week factory lead time
- Dual-row 10-position configuration at 1.27 mm pitch enabling compact high-density board-to-board connections in space-constrained designs
Applications
The SFM-105-02-L-D-A-K-TR is designed for high-density board-to-board and mezzanine card interconnect applications in telecom, industrial, and computing systems where reliable 10-position dual-row connections at 1.27 mm pitch are required. Its Tiger Eye beryllium copper contacts with gold plating make it particularly suited for applications demanding extended mating cycles and low contact resistance, such as hot-swappable module sockets and test fixture interfaces. The tape-and-reel format simplifies automated assembly integration for high-volume production of networking blades, FPGA daughter cards, and embedded computing modules.

Frequently Asked Questions
What makes the Tiger Eye contact design of the SFM-105-02-L-D-A-K-TR advantageous over standard socket contacts?
The Tiger Eye contact design uses a beryllium copper spring geometry that delivers a higher and more consistent normal force compared to standard stamped contacts, resulting in lower and more stable contact resistance over thousands of mating cycles in applications such as hot-swap module sockets and high-cycle test fixtures operating at 1.27 mm pitch.
What is the contact finish specification for the SFM-105-02-L-D-A-K-TR mating and termination surfaces?
The mating surface uses 10 µin (0.25 µm) gold over nickel barrier, providing excellent corrosion resistance and consistent low contact resistance, while the termination finish is tin with a nickel barrier, ensuring reliable solderability during reflow assembly and long-term solder joint integrity.
Is the SFM-105-02-L-D-A-K-TR suitable for high-volume automated assembly and what is the typical lead time?
Yes, the -TR suffix confirms tape-and-reel packaging fully compatible with automated SMT pick-and-place equipment and reflow soldering up to 260°C. The factory lead time is typically 1 week, making it practical for just-in-time manufacturing of boards requiring 10-position dual-row 1.27 mm pitch socket connectors.
How does the SFM-105-02-L-D-A-K-TR perform in demanding industrial or test-and-measurement environments?
The combination of beryllium copper contacts, 10 µin gold mating finish, and Tiger Eye geometry ensures the SFM-105-02-L-D-A-K-TR maintains stable electrical performance across operating temperatures typically ranging from -55°C to +125°C and withstands thousands of mating cycles, making it a reliable choice for test fixture sockets and industrial module connectors with high duty cycles.
