Frequently Asked Questions
What is the pitch and row configuration of the SFM-122-02-L-D-A-K connector?
The SFM-122-02-L-D-A-K features a dual-row, 44-position layout with a 0.050" (1.27 mm) pitch, making it a high-density surface-mount socket strip well suited for compact board-to-board interconnects.
Which PCB assembly method does the SFM-122-02-L-D-A-K support, and how does that affect board layout?
The connector uses surface-mount termination, which eliminates the need for through-hole drilling and allows a smaller PCB footprint. Its 1.27 mm pitch and 44 pins across 2 rows enable dense routing in a minimal board area.
When is SFM-122-02-L-D-A-K a better choice than a 2.00 mm pitch dual-row connector for mezzanine stacking?
The SFM-122-02-L-D-A-K's 1.27 mm (0.050") pitch delivers nearly 60% higher pin density compared to 2.00 mm pitch alternatives, making it the preferred choice for mezzanine designs where board real estate is limited and 44 signals must be routed in a compact area without sacrificing reliability.
What industries or end applications commonly use the SFM-122-02-L-D-A-K?
This 44-position, 1.27 mm pitch SMT socket is commonly used in telecommunications line cards, networking switches, FPGA development boards, industrial automation controllers, and aerospace avionics systems that require high pin-count board-to-board connections in a space-constrained environment.
