Frequently Asked Questions
What contact finish does the SFM-120-02-STL-D use for mating, and why does it matter for reliability?
The SFM-120-02-STL-D uses a gold (30 micro-inch) mating contact finish across all 40 positions. Gold provides corrosion resistance and maintains low contact resistance through hundreds of mating cycles, making it critical for high-reliability aerospace and defense applications.
What are the body dimensions of the SFM-120-02-STL-D, and how does its size fit compact PCB designs?
The SFM-120-02-STL-D has a body length of 1.155 inches, breadth of 0.145 inch, and depth of 0.185 inch. This compact envelope accommodates 40 dual-row contacts at 0.050" pitch, enabling high-density board-to-board connections in space-constrained PCB layouts.
When should engineers choose the SFM-120-02-STL-D over socket strips with tin-only mating contacts?
Engineers should select the SFM-120-02-STL-D when long-term reliability across 40 signal paths is critical, such as in aerospace or defense systems subjected to vibration and humidity. The 30 micro-inch gold mating finish outperforms tin-only contacts in corrosion resistance and insertion-cycle durability.
