Frequently Asked Questions
What is the pin count per row and total position count in the SFM-148-L2-STL-D-A-K?
The SFM-148-L2-STL-D-A-K has 96 total positions in a dual-row configuration with 48 positions per row, all at 0.050 inch (1.27 mm) pitch. Gold-plated contacts provide stable mating interface performance, and the polarization key prevents the 180-degree mating error that would swap all 96 signal connections and potentially damage connected circuits.
How does the L2 column designator affect the stack height when mating the SFM-148-L2-STL-D-A-K?
The L2 designator specifies the column height of the socket body, determining the board separation distance when mated with a corresponding SFM plug. For the SFM series, column height designators define stack heights ranging from approximately 3 mm to over 20 mm, and L2 selects a specific intermediate height appropriate for enclosure clearances typically between 5 mm and 10 mm above the PCB surface.
When is the SFM-148-L2-STL-D-A-K preferred over a lower-pin-count connector like the SFM-125 in a new PCB design?
The SFM-148-L2-STL-D-A-K is preferred when the interface requires between 73 and 96 signal, power, or ground connections over a single connector body, avoiding the need to place two smaller connectors side by side. This matters in FPGA I/O expansion daughter cards, high-speed serial bus interfaces, and data acquisition boards where consolidating 96 pins into one 0.050 inch pitch connector reduces PCB routing complexity and connector count.
