Key Features
- 78 dual-row positions on a compact 0.050" (1.27 mm) pitch, enabling high-density surface-mount interconnects
- Gold-plated contacts rated at 1 A per pin for reliable low-resistance mating in demanding environments
- High-reliability socket strip construction engineered for repeated mating cycles in industrial and instrumentation designs
Applications
The SFM-139-T2-S-D-A is well suited for high-density board-to-board and mezzanine connections in test and measurement instruments, data-acquisition systems, and industrial control modules. Its surface-mount 0.050" pitch footprint makes it a preferred choice for compact PCB designs where space is critical and a large number of signal lines must be routed between stacked boards.

Frequently Asked Questions
What is the pitch and contact rating of the SFM-139-T2-S-D-A socket strip?
The SFM-139-T2-S-D-A uses a 0.050" (1.27 mm) pitch and provides 78 dual-row positions with gold-plated contacts rated at 1 A per pin, making it ideal for high-density surface-mount signal routing.
Which board-stacking applications benefit most from the SFM-139-T2-S-D-A?
Mezzanine and daughter-card assemblies in test-and-measurement equipment, industrial control modules, and data-acquisition cards benefit from this 78-position, 0.050" pitch surface-mount socket, which supports high pin counts in compact PCB envelopes.
How does the dual-row layout of the SFM-139-T2-S-D-A compare to single-row alternatives?
A dual-row arrangement accommodates 78 contacts within roughly half the row length required by a single-row connector at the same 0.050" pitch, reducing the PCB footprint by approximately 50% along the connector axis while maintaining the same 1 A per-pin current capacity.
