Frequently Asked Questions
How many signal contacts does SFM-145-L2-STL-D-A-P provide and at what pitch?
SFM-145-L2-STL-D-A-P offers 90 contacts arranged in a dual-row 2×45 configuration with a 0.050" (1.27 mm) pitch, making it well suited for high-density PCB interconnect applications where compact signal routing is required.
Which board stacking or mezzanine designs can the SFM-145-L2-STL-D-A-P support?
This socket strip is designed for mating with SFM-series pin headers and board-to-board stacking assemblies. With 90 positions at 1.27 mm pitch and surface-mount termination, it fits compact mezzanine board designs in industrial, telecom, and embedded computing systems operating over typical temperature ranges.
What mechanical feature distinguishes SFM-145-L2-STL-D-A-P from standard SFM connectors?
The STL suffix indicates stainless steel hardware components, providing higher mechanical durability and resistance to corrosion compared to standard plated variants. This feature is particularly valuable in environments requiring robust mating across hundreds of mating cycles or exposure to vibration and shock.
Is SFM-145-L2-STL-D-A-P appropriate for automated SMT assembly processes?
Yes. The SFM-145-L2-STL-D-A-P uses a surface-mount termination style, making it compatible with standard SMT reflow assembly processes. Its 0.050" (1.27 mm) pitch and 90-pin count suit pick-and-place equipment and high-volume PCB production lines.
