Frequently Asked Questions
What pitch and row configuration does the SFM-126-L2-SM-D-A-K-TR use?
The SFM-126-L2-SM-D-A-K-TR uses a 0.050" (1.27 mm) pitch in a dual-row configuration, providing 52 total positions. This tight pitch allows dense signal routing on PCBs where board space is limited, making it ideal for compact embedded and industrial designs.
Which termination style does the SFM-126-L2-SM-D-A-K-TR use, and how does that affect PCB assembly?
The SFM-126-L2-SM-D-A-K-TR uses surface mount (SMT) termination, which allows standard pick-and-place and reflow solder assembly. This eliminates through-hole drilling requirements and supports double-sided PCB population. The SMT pads are compatible with standard 1.27 mm pitch land patterns used in automated assembly lines.
In what applications is the SFM-126-L2-SM-D-A-K-TR commonly deployed?
This 52-position, 0.050" pitch SMT socket strip is commonly used in board-to-board mezzanine interconnects, data acquisition modules, embedded computing platforms, and industrial control systems. Its high-reliability contacts ensure consistent signal integrity across 8 or more mating cycles in demanding environments.
How does the SFM-126-L2-SM-D-A-K-TR compare to a through-hole socket strip of similar pitch?
Compared to through-hole alternatives, the SFM-126-L2-SM-D-A-K-TR offers a lower profile and eliminates drilling 52 holes per connector, saving PCB fabrication cost and assembly time. The 1.27 mm pitch SMT design supports finer-pitch routing layers and is compatible with modern automated reflow processes.
