Key Features
- 46-position dual-row 0.050" (1.27 mm) pitch for maximum signal density on compact PCBs
- Gold-plated contacts providing low-contact-resistance and long-term corrosion resistance
- Surface mount (SMT) termination style for compatibility with automated reflow soldering
- High-reliability design suited for demanding industrial and instrumentation environments
Applications
The SFM-123-02-STL-D-A-K is well-suited for high-channel-count board-to-board signal routing in industrial control systems, data acquisition equipment, and communication modules that require 46 positions in a compact 0.050" pitch dual-row layout. Its SMT construction makes it compatible with automated PCB assembly lines operating at standard reflow temperatures up to 260°C. Engineers also use this connector in test and measurement instrumentation where dense, reliable signal connections between boards are essential.

Frequently Asked Questions
What is the position count and pitch of the SFM-123-02-STL-D-A-K, and how does it affect PCB layout density?
The SFM-123-02-STL-D-A-K provides 46 positions in a dual-row arrangement on a 0.050" (1.27 mm) pitch, enabling high signal density while occupying only a narrow PCB footprint — roughly 29.21 mm in length — making it ideal for space-constrained board designs.
What reflow solder temperature is the SFM-123-02-STL-D-A-K rated for during PCB assembly?
The SFM-123-02-STL-D-A-K is designed for surface mount reflow soldering and is compatible with standard lead-free reflow profiles up to 260°C peak temperature, ensuring reliable solder joints with 46 positions across dual rows in automated assembly processes.
Which applications benefit most from the SFM-123-02-STL-D-A-K dual-row socket strip?
Applications that benefit most include industrial automation controllers, multi-channel data acquisition modules, and embedded computing systems where 46 signal lines must cross board boundaries reliably. The 0.050" pitch and gold-plated contacts ensure signal integrity across all 46 positions even in vibration-prone environments.
When would an engineer choose SFM-123-02-STL-D-A-K over a lower-position SFM connector variant?
Engineers select the 46-position SFM-123-02-STL-D-A-K over lower-count variants like the SFM-103 (6 positions) when a design requires routing more than 20 differential or single-ended signals between boards, minimizing the number of connector pairs from 4+ smaller connectors down to a single 46-position mated pair.
