Frequently Asked Questions
How many positions and rows does the SFM-149-T2-LM-D-A-K socket strip provide?
The SFM-149-T2-LM-D-A-K provides 98 positions arranged in a dual-row (2 rows x 49 positions) configuration with a 0.050" (1.27 mm) pitch, making it one of SAMTEC's higher-count surface mount socket strips for dense board interconnects.
Which SAMTEC male header series mate with the SFM-149-T2-LM-D-A-K for a complete 0.050" pitch connector pair?
The SFM-149-T2-LM-D-A-K mates with SAMTEC TSM and TMS series male headers sharing the same 0.050" (1.27 mm) pitch. These complementary 98-position dual-row headers provide a secure, low-profile board-to-board interconnect system supporting signal integrity requirements in compact SMT designs.
What does the LM designation in SFM-149-T2-LM-D-A-K indicate about the contact construction?
The LM designation stands for Low-Metallic Mass, meaning the contacts have a reduced metal volume compared to standard contacts. This lowers thermal mass during soldering—critical for SMT reflow processes—and helps prevent heat-related damage to adjacent components on boards with tight component spacing of 1.27 mm pitch.
In which high-reliability application segments is the SFM-149-T2-LM-D-A-K most commonly deployed?
This connector is commonly deployed in industrial automation, test and measurement instruments, military communications equipment, and embedded computing modules. Its 98-position, dual-row, 0.050" pitch design handles dense I/O routing, and the high-reliability rating supports environments where consistent electrical performance over thousands of mating cycles is required.
