Key Features
- 70-position dual-row SMT socket strip with 0.050" (1.27 mm) pitch and gold-plated mating contacts over nickel barrier for reliable low-resistance connections
- High-reliability surface-mount construction with body length of 1.905 inches providing robust board retention without through-hole vias
- RoHS-compliant lead-free (Pb-free) design meeting environmental regulations for commercial and industrial equipment
Applications
The SFM-135-02-H-D is well-suited for high-density signal and data interconnects in communications equipment, industrial control systems, and embedded computing platforms requiring 70 mating positions at 0.050" pitch. Gold-plated contacts with a nickel barrier ensure stable contact resistance over thousands of mating cycles, making this socket strip ideal for test and measurement fixtures and module-to-module interfaces. Its SMT footprint simplifies automated assembly and is compatible with standard reflow soldering processes.

Frequently Asked Questions
What contact finish is used on the SFM-135-02-H-D and why does it matter for reliability?
The SFM-135-02-H-D uses gold (Au) mating contacts deposited over a nickel (Ni) barrier layer. Gold plating provides excellent corrosion resistance and stable, low contact resistance across thousands of mating cycles. The nickel barrier prevents gold diffusion into the base material, extending connector service life in high-reliability applications at 70 positions and 0.050" pitch.
How does the SFM-135-02-H-D body size affect PCB layout planning?
With a body length of 1.905 inches, body breadth of 0.145 inches, and body depth of 0.185 inches, the SFM-135-02-H-D occupies a well-defined SMT footprint. Designers can place 70 signal connections in a compact, low-profile area, reducing routing complexity compared to discrete through-hole pin headers and saving valuable PCB space in dense electronics assemblies.
Is the SFM-135-02-H-D suitable for lead-free assembly processes?
Yes, the SFM-135-02-H-D carries a Pb-free (lead-free) designation, making it compatible with RoHS-compliant reflow solder processes. The gold-over-nickel contact finish withstands standard lead-free solder temperatures, and the 70-position, 0.050" pitch SMT design supports automated placement and reflow without degrading contact performance.
