What are the key features of SFM-129-L2-FM-D-A-K?
- 58-position dual-row socket layout on 0.050 inch (1.27 mm) pitch enabling very high contact density for compact mezzanine and board stacking designs
- High-reliability socket strip construction engineered for consistent electrical contact across hundreds of mating cycles in demanding environments
- Flush-mount (FM) SMT termination style minimizes connector height, enabling low-profile board stack assemblies and efficient PCB real estate usage
What is SFM-129-L2-FM-D-A-K used for?
The SFM-129-L2-FM-D-A-K is suited for high-density mezzanine interconnects in embedded computing, FPGA daughterboards, and RF front-end modules where 58 contacts must be reliably bridged at a 0.050 inch pitch. Its flush-mount SMT tails allow integration into single-reflow PCB assemblies without protruding pins, simplifying the manufacturing process. The high-reliability contact design supports repeated plug-and-play configurations in test fixtures, evaluation platforms, and field-serviceable industrial computing modules.

Frequently Asked Questions
How should SFM-129-L2-FM-D-A-K be matched to an existing design?
The available product data establishes these design facts: SAMTEC SFM-129-L2-FM-D-A-K is a 58-position dual-row high-reliability surface mount socket strip with 0.050 inch pitch and flush-mount SMT termination, designed for precise board-to-board mating in dense PCB assemblies. Match those values to 1 controlled PCB footprint and the exact mating interface before layout release.
What engineering evidence supports approval of SFM-129-L2-FM-D-A-K?
Use 1 controlled PCB footprint to confirm the contact pattern, mating direction, and termination; then inspect 2 prototype assemblies for mechanical fit.
Which BOM controls are useful when ordering SFM-129-L2-FM-D-A-K?
Keep the full suffix on the purchase order, request 1 manufacturer certificate, and compare 2 incoming samples with the controlled BOM and package drawing.
