Frequently Asked Questions
What contact pitch and row configuration does the SFM-120-02-L-D-A-P use?
The SFM-120-02-L-D-A-P uses a 0.050" (1.27 mm) pitch dual-row layout with 40 total positions, making it suitable for high-density surface-mount board-to-board stacking applications where board space is at a premium.
How does the Tiger Eye contact improve long-term reliability in the SFM-120-02-L-D-A-P?
The Tiger Eye contact design provides a wiping action during mating, combined with a gold (10 µin) finish. This reduces contact resistance and accommodates slight misalignment, extending the connector's functional life beyond 100 mating cycles in typical SMT applications.
Which PCB assembly processes are compatible with the SFM-120-02-L-D-A-P positioning pin feature?
The positioning pin option on the SFM-120-02-L-D-A-P secures the 0.050" pitch connector precisely during standard SMT reflow soldering. The 1.125 inch body length and 0.185 inch body depth keep the part stable in pick-and-place and wave-solder processes, minimizing tombstoning and solder bridging.
In what embedded or industrial applications is the SFM-120-02-L-D-A-P typically used?
This 40-position dual-row socket strip is commonly deployed in industrial backplane systems, embedded computing mezzanine cards, and automated test equipment. Its surface-mount profile and gold-plated contacts support operating environments requiring reliable signal integrity across 40 channels at 0.050" spacing.
