Frequently Asked Questions
How many positions and rows does the SFM-127-02-STL-D-A-K connector have, and what is its pitch?
The SFM-127-02-STL-D-A-K is a 54-position, dual-row socket strip with a 0.050" (1.27 mm) pitch. This high-density layout allows it to accommodate up to 54 contacts in a compact footprint, making it well-suited for board-to-board and module interconnect applications where space is limited.
What mounting style does the SFM-127-02-STL-D-A-K use, and how does it affect PCB assembly?
The SFM-127-02-STL-D-A-K uses surface mount technology (SMT), which means it can be placed and soldered using standard automated reflow processes. The SMT format with 54 positions at 0.050" pitch is compatible with high-volume PCB assembly lines and reduces through-hole drilling requirements on the host board.
For which applications is the SFM-127-02-STL-D-A-K high-reliability socket strip best suited?
The SFM-127-02-STL-D-A-K is designed for high-reliability applications in industrial controls, telecommunications, defense, and medical equipment where board-to-board connections with 54 contacts at 1.27 mm pitch must endure vibration, thermal cycling, and repeated mating. Its gold-plated contacts ensure low resistance and long mating life exceeding hundreds of cycles.
