Key Features
- 92-position dual-row layout on 1.27 mm (0.050 inch) pitch enabling high-density mezzanine card-to-card stacking in compact SMT designs
- High-reliability contact construction with gold-plated contacts rated for 500+ mating cycles, ensuring long service life in harsh environments
- Surface mount termination compatible with standard reflow soldering processes for automated PCB assembly in industrial and defense equipment
Applications
The SFM-146-L2-L-D-A-K is used in high-density mezzanine and daughter-card stacking assemblies where 92 SMT signal connections are needed in a 1.27 mm pitch footprint. Its high-reliability contact design suits defense electronics, avionics, and industrial control boards requiring long mating cycle endurance and stable signal integrity. The dual-row surface mount format also supports FPGA expansion cards and communications modules where PCB real estate is constrained.

Frequently Asked Questions
How many mating positions does the SFM-146-L2-L-D-A-K provide and what is the contact pitch?
The connector provides 92 mating positions arranged in 2 rows on a 1.27 mm (0.050 inch) pitch. This high-density layout allows routing 92 signals across a footprint roughly 58 mm long, enabling compact mezzanine stacking in FPGA carrier boards and communications modules.
For which board stacking heights is the SFM-146 series suitable in avionics or defense assemblies?
The SFM-146-L2-L-D-A-K mates with SAMTEC TSM or SFM plug strips to set a defined board-to-board stack height, typically 4 mm to 10 mm depending on the mating plug variant. This controlled standoff suits avionics chassis where vibration isolation and consistent 1.27 mm pitch alignment over 500+ mating cycles are required.
Can the SFM-146-L2-L-D-A-K be assembled using standard reflow soldering, and what temperature profile does it support?
Yes, the surface mount termination is designed for standard Pb-free reflow soldering up to 260°C peak temperature per IPC/JEDEC J-STD-020. The gold-plated contacts withstand the reflow profile without oxidation, making the connector compatible with automated SMT assembly lines processing industrial and defense PCBs.
