Key Features
- 92-position dual-row configuration on ultra-fine 0.050-inch (1.27 mm) pitch delivering high-density signal routing in a minimal PCB footprint
- High-reliability female socket contacts engineered for consistent low-resistance mating across hundreds of insertion cycles in demanding environments
- Surface-mount termination enables standard SMT reflow assembly without through-hole drilling, simplifying high-density multilayer PCB fabrication
Applications
The SFM-146-T2-FM-D is suited for high-density board-to-board interconnects in FPGA evaluation boards, military computing modules, and industrial data acquisition systems where 92 signals must be routed across a 0.050-inch pitch SMT interface. Its high-reliability socket construction supports applications demanding low contact resistance and mechanical stability under vibration, such as avionics daughter cards and rugged embedded computing backplanes.

Frequently Asked Questions
How dense is the SFM-146-T2-FM-D signal layout compared to standard 0.100-inch pitch connectors?
The SFM-146-T2-FM-D operates on a 0.050-inch (1.27 mm) pitch, which is exactly half the spacing of standard 0.100-inch connectors. This allows 92 contacts to occupy roughly the same PCB footprint length as a 46-position 0.100-inch strip, cutting board area consumption by approximately 50% for the same signal count on dense multilayer PCBs.
What makes the SFM-146-T2-FM-D a high-reliability socket choice for aerospace and defense applications?
The SFM-146-T2-FM-D uses precision-machined female socket contacts rated for hundreds of mating cycles with consistent contact resistance below 20 milliohms. Its SMT termination provides a robust solder joint under mechanical shock and vibration, making it compliant with the insertion-cycle and environmental requirements typical of MIL-grade avionics daughter card and field-programmable module applications.
Can the SFM-146-T2-FM-D be reflowed on a standard SMT line without additional tooling?
Yes, the SFM-146-T2-FM-D surface-mount terminations are compatible with standard lead-free reflow solder paste at peak temperatures up to 260 degrees C. No through-hole drilling or wave soldering is needed, so it fits into standard SMT production lines alongside 0402 and 0603 passive components, simplifying PCB fabrication for high-density 92-position connector assemblies.
When should designers choose the SFM-146-T2-FM-D over a 0.100-inch pitch alternative for a new high-density board?
When board area is limited and signal count exceeds 46 channels on one connector, the 0.050-inch pitch SFM-146-T2-FM-D provides 92 positions in approximately the same length as a 46-position 0.100-inch strip. This pitch reduction is particularly valuable on 4-layer or 6-layer boards where routing escape vias for 92 through-hole contacts would consume more than 30% of inner-layer routing channels.
