Key Features
- Tiger Eye beryllium copper contacts provide superior spring force and >100 mating cycle reliability, maintaining low contact resistance over the connector's lifetime
- 10 µin gold contact finish on mating surfaces ensures corrosion resistance and stable electrical performance across the full 20-pin dual-row interface
- Low-profile (L) housing with press-fit (P) mounting minimizes board-to-board stack height and improves mechanical retention during vibration
Applications
The SFM-110-02-L-D-P-TR is ideal for compact mezzanine board stacking in portable instruments, FPGA module interfaces, and space-constrained embedded computing designs requiring 20 high-reliability connections at 0.050" pitch. Its Tiger Eye contacts and gold finish make it particularly suitable for high-cycle field-replaceable modules where reliable contact performance across repeated insertions is essential.

Frequently Asked Questions
What makes the Tiger Eye contact in the SFM-110-02-L-D-P-TR superior to standard socket contacts?
The Tiger Eye contact is made from beryllium copper with a unique geometry that provides higher normal force than conventional socket contacts at 0.050" (1.27 mm) pitch. This results in contact resistance below 20 mΩ maintained over 100 or more mating cycles, making the SFM-110-02-L-D-P-TR a preferred choice for test sockets, field-replaceable modules, and any 20-pin interface requiring long-term reliable performance.
What is the gold plating thickness on the mating contacts of the SFM-110-02-L-D-P-TR?
The SFM-110-02-L-D-P-TR features 10 µin (0.25 µm) gold over nickel on its mating contacts, while the termination contacts use tin with a nickel barrier. The 10 µin gold layer provides corrosion resistance and maintains low, stable contact resistance even in humid or mildly corrosive environments, suitable for industrial and communications equipment operating at temperatures from -55°C to +125°C.
How compact is the SFM-110-02-L-D-P-TR for a 20-pin mezzanine interface compared to .100" pitch alternatives?
At 0.050" (1.27 mm) pitch dual-row, the SFM-110-02-L-D-P-TR achieves a 20-pin interface in a body approximately 12.7 mm long, which is roughly half the length of an equivalent .100" pitch 20-pin connector at 25.4 mm. The low-profile (L) housing further reduces stack height, enabling mezzanine assemblies with board-to-board gaps as small as 4 mm to 6 mm.
