Frequently Asked Questions
How many total positions does the SFM-126-T2-LM-D-A provide and how are they arranged?
The SFM-126-T2-LM-D-A provides 52 total positions arranged in a dual-row configuration with 26 contacts per row at a 0.050" (1.27 mm) pitch. This dual-row layout allows designers to achieve high connection density within a compact SMT footprint for board-to-board and mezzanine interconnect applications.
For which types of high-density PCB designs is the SFM-126-T2-LM-D-A most appropriate?
The SFM-126-T2-LM-D-A is best suited for high-density mezzanine board designs, FPGA daughter card interconnects, and modular rack computing systems that require 52 reliable signal contacts within a minimal 0.050" pitch SMT footprint. It supports applications that demand stable electrical performance across repeated mating cycles in industrial and telecom environments.
When should a designer choose SFM-126-T2-LM-D-A over a lower-count variant like SFM-108?
Designers should choose the SFM-126-T2-LM-D-A over lower-count SFM-108 variants when their interface requires 52 or more signal lines in a single dual-row connector instead of 16 positions. For FPGA carrier boards or high-channel-count data acquisition front ends needing 52-position connectivity at 1.27 mm pitch, the SFM-126 eliminates the need for multiple smaller connectors.
