Key Features
- 70-position dual-row polarized socket strip at 0.050 inch pitch preventing incorrect mating in high-density assemblies
- Tin/lead over nickel barrier contact termination providing reliable solder joint integrity and corrosion resistance
- Tape-and-reel packaging enabling automated SMT pick-and-place assembly of 70-pin high-reliability board connectors
Applications
The SFM-135-02-STL-D-A-K-TR is suited for high-density board-to-board connections in server daughter cards, network switches, and industrial computing platforms requiring 70 polarized signal contacts at 0.050 inch pitch. Its polarized socket design prevents mismating during assembly and field service, reducing risk in complex multi-board systems. The tape-and-reel format supports efficient automated placement in high-volume SMT production environments.

Frequently Asked Questions
What polarization feature does the SFM-135-02-STL-D-A-K-TR provide and why is it important?
The SFM-135-02-STL-D-A-K-TR includes polarization that physically prevents incorrect mating orientation across its 70 positions at 0.050 inch pitch, protecting sensitive circuits from reverse-connection damage during assembly and field maintenance of high-density board stacking systems.
What contact finish does the SFM-135-02-STL-D-A-K-TR use on its termination, and how does it affect soldering?
The connector uses tin/lead over nickel barrier contact termination, which provides excellent solderability for SMT reflow processes and corrosion resistance at the interface, ensuring reliable 70-position solder joints on the PCB during standard reflow soldering assembly.
What factory lead time should procurement teams expect for the SFM-135-02-STL-D-A-K-TR?
The SFM-135-02-STL-D-A-K-TR carries a factory lead time of approximately 5 weeks and 5 days, meaning procurement teams should plan orders well ahead for production runs and consider safety stock for programs using this 70-position 0.050 inch pitch socket strip.
How does the 70-position count of SFM-135-02-STL-D-A-K-TR compare to smaller variants in the SFM series?
With 70 positions at 0.050 inch pitch, the SFM-135 provides 10 more contacts than the 60-position SFM-130 and 22 more than the 48-position SFM-124, making it the appropriate choice when interface buses exceed 60 signals without stepping up to a different connector series.
