Key Features
- 92-position dual-row design at 0.050" (1.27 mm) pitch delivers maximum signal density per unit board area
- Surface-mount termination with flux-manageable (FM) standoff enables reliable reflow soldering and controlled flux escape
- High-reliability gold-plated contacts rated for repeated mating cycles in demanding industrial interconnect environments
Applications
The SFM-146-L2-FM-D is designed for high-density mezzanine and board-to-board signal interconnect in industrial automation, embedded computing modules, and defense electronics. Its 92-position dual-row layout at 0.050" pitch accommodates a large number of signal lines within a minimal PCB footprint. The flux-manageable (FM) standoff variant ensures reliable reflow assembly by managing solder flux migration during high-volume SMT processing.

Frequently Asked Questions
What does the flux-manageable (FM) standoff on the SFM-146-L2-FM-D provide during reflow assembly?
The FM (flux-manageable) standoff on the SFM-146-L2-FM-D creates a controlled gap between the connector body and PCB during reflow soldering, allowing flux vapors to escape without being trapped beneath the component. This reduces the risk of solder voids and improves joint quality across all 92 positions at 0.050" (1.27 mm) pitch.
How does the 92-position count of SFM-146-L2-FM-D compare to smaller SFM variants in space-critical designs?
With 92 positions arranged in 2 rows at 1.27 mm pitch, the SFM-146-L2-FM-D routes 46 signals per row across a footprint of roughly 58.4 mm in length, consolidating significantly more connectivity than 50- or 60-position alternatives into a single connector, reducing total connector count and board routing complexity.
What industries most commonly use the SFM-146-L2-FM-D socket strip?
The SFM-146-L2-FM-D is most common in defense electronics, medical imaging equipment, industrial PLCs, and high-performance embedded computing platforms where 92-pin dual-row 0.050" pitch connectivity, high-reliability gold contacts, and SMT compatibility are mandatory design requirements for dense backplane and daughtercard interfaces.
What mating plug header is recommended for the SFM-146-L2-FM-D?
SAMTEC recommends mating the SFM-146-L2-FM-D with SAMTEC SMM or SFM plug headers sharing the 0.050" (1.27 mm) pitch and 92-position dual-row pattern. The matched pair provides a 4-point contact wipe per pin, ensuring low contact resistance and reliable electrical performance across all 92 mated positions.
