Key Features
- 20-position dual-row socket strip on 0.050 inch (1.27 mm) pitch with gold mating contacts for superior signal integrity and low contact resistance
- Surface mount (SM) termination with tin over nickel barrier enables automated SMT assembly and excellent solderability on standard reflow profiles
- High-reliability female socket design with 0.655 inch body length rated for thousands of mating cycles in demanding aerospace, industrial, and embedded applications
Applications
The SFM-110-T2-SM-D is suited for high-density board-to-board or board-to-module stacking applications in embedded computing, RF modules, and industrial control systems. Its 0.050 inch pitch with 20 positions allows significant signal density in a 0.655 inch footprint, making it ideal for compact SBC expansion connectors and daughtercard interfaces. The gold mating contacts ensure reliable electrical continuity in applications subject to repeated insertion cycles or environmental stress.

Frequently Asked Questions
What are the key electrical and mechanical specifications of the SFM-110-T2-SM-D socket strip?
The SFM-110-T2-SM-D is a 20-position dual-row socket with 0.050 inch (1.27 mm) pitch and a body measuring 0.655 inch long by 0.185 inch deep by 0.145 inch wide. It uses gold-plated mating contacts and tin over nickel barrier termination contacts, making it suitable for high-cycle-count board-to-board connections requiring low contact resistance below 20 mΩ.
Why choose gold mating contacts over tin contacts in the SFM-110-T2-SM-D for high-reliability designs?
Gold mating contacts on the SFM-110-T2-SM-D provide significantly lower and more stable contact resistance than tin, typically maintaining under 20 mΩ across thousands of mating cycles. Gold also resists oxidation at elevated temperatures up to 125°C, making it the preferred choice for aerospace, military, and medical applications where contact reliability is non-negotiable.
How does the surface mount termination of SFM-110-T2-SM-D benefit PCB manufacturing?
The surface mount (SM) termination allows the SFM-110-T2-SM-D to be placed and reflowed using standard SMT production equipment, eliminating through-hole drilling and wave solder steps. Tin over nickel barrier termination contacts ensure excellent solder joint wetting on standard SAC305 lead-free solder at 260°C peak reflow temperature, supporting high-volume automated assembly.
What application scenarios benefit most from the SFM-110-T2-SM-D dual-row socket strip configuration?
The SFM-110-T2-SM-D dual-row 20-pin configuration at 0.050 inch pitch delivers 20 signals in a 0.655 inch board footprint, making it ideal for compact FPGA expansion headers, RF daughterboard interconnects, and SBC module interfaces. Applications requiring dense signal routing with fewer than 1 inch of connector length, such as embedded vision systems or industrial sensor modules, benefit most from this format.
