What are the key features of SFM-127-L2-LM-D-A-K?
- 54-position dual-row socket strip on 1.27 mm (0.050 inch) fine pitch, providing 27 contacts per row for very high signal density
- Low-mating-height (LM suffix) design reduces board-to-board stack height for compact multi-PCB assemblies
- High-reliability contact system rated for extended insertion cycles in field-serviceable and production test applications
- Surface mount termination supports automated SMT reflow assembly with lead-free solder compatibility
What is SFM-127-L2-LM-D-A-K used for?
The SFM-127-L2-LM-D-A-K serves high-density board-to-board interconnect in FPGA development platforms, high-speed signal processing modules, and industrial I/O expansion cards that require 54 independent signal connections. The 0.050 inch pitch allows these 54 connections in a footprint suitable for compact PCB designs where board space is at a premium. Its high-reliability contacts and low-mating-height configuration make it well suited for stacked board assemblies in rugged instrumentation and communications systems.
