Frequently Asked Questions
What contact count and pitch does the SFM-123-T2-SM-D-A-K-TR provide in its dual-row configuration?
The SFM-123-T2-SM-D-A-K-TR features 46 positions in a dual-row layout with a 0.050" (1.27 mm) pitch. This configuration provides high contact density per unit length, making it suitable for parallel data bus and mixed signal interconnects in compact mezzanine board designs.
How does the SFM-123-T2-SM-D-A-K-TR compare to the SFM-127 variant for high-density bus routing?
The SFM-123-T2-SM-D-A-K-TR provides 46 positions versus 54 positions on the SFM-127, both at 0.050" (1.27 mm) pitch and dual-row surface mount format. Designers select the SFM-123 when the bus width requires fewer than 54 signals, saving board footprint while maintaining the same high reliability contact construction and assembly process compatibility.
What environments or industries benefit most from the high reliability rating of the SFM-123-T2-SM-D-A-K-TR?
Industries such as industrial automation, telecommunications, and embedded computing benefit most from the SFM-123-T2-SM-D-A-K-TR high reliability rating, where vibration, thermal cycling, and repeated mating cycles could degrade standard connectors. The robust contact retention ensures stable signal paths at 46 positions even after thousands of mating cycles or in elevated temperature environments up to the connector's rated operating range.
