What are the key features of SFM-124-02-LM-D-A-K?
- 48-position dual-row socket strip on 1.27 mm (0.050 inch) fine pitch for high-density signal routing in compact PCB designs
- High-reliability contacts rated for extended mating cycle life, ideal for field-serviceable board-to-board connections
- Low-mating-height (LM suffix) configuration minimizes stack height between two mating PCBs
- Surface mount termination eliminates through-hole drilling and simplifies automated SMT assembly workflows
What is SFM-124-02-LM-D-A-K used for?
The SFM-124-02-LM-D-A-K is well suited for high-density board-to-board interconnect in embedded computing modules, FPGA daughter cards, and industrial I/O expansion boards requiring 48 signal connections. Its 1.27 mm fine pitch allows routing of 48 lines in a footprint smaller than an equivalent 2.54 mm pitch connector, enabling tighter PCB designs. The high-reliability socket contacts support repeated board removal and reinsertion in systems requiring field maintenance.

Frequently Asked Questions
How many signal connections does the SFM-124-02-LM-D-A-K support per connector on a 1.27 mm pitch?
The SFM-124-02-LM-D-A-K supports 48 signal connections arranged in 2 rows of 24 contacts each, all on a 1.27 mm (0.050 inch) pitch. This high pin count on a fine pitch enables routing of 48 independent signals in a PCB footprint substantially smaller than equivalent 2.54 mm pitch connectors.
What does the LM suffix indicate for the SFM-124-02-LM-D-A-K and why is it important for stacked PCB designs?
The LM suffix designates a low-mating-height profile, meaning the SFM-124-02-LM-D-A-K and its mating header achieve a reduced board-to-board stack height, typically around 4 mm to 5 mm. This low profile is essential in multi-board assemblies where the total system height must fit within a constrained enclosure, such as compact industrial controllers or medical devices.
Which mating header family is compatible with the SFM-124-02-LM-D-A-K at 0.050 inch pitch?
The SFM-124-02-LM-D-A-K mates with SAMTEC TSM or SSM series pin headers on the same 1.27 mm (0.050 inch) dual-row pitch. Designers can select from various stack heights in the mating header family to achieve the required board separation, typically from 3 mm to 15 mm, without altering the 48-position socket footprint.
For a design requiring 48 board-to-board connections with field-replaceable boards, how does the SFM-124-02-LM-D-A-K compare to soldered ribbon cable?
The SFM-124-02-LM-D-A-K enables tool-free board removal and reinsertion across its rated mating cycle life, providing far greater serviceability than a soldered ribbon cable connection at 48 positions. Ribbon cables require desoldering tools and risk PCB pad damage during rework, while the 1.27 mm pitch socket allows field technicians to replace boards without specialized soldering equipment.
