Key Features
- 52-position dual-row layout at 0.050" (1.27 mm) pitch delivers high-density signal connectivity in a compact SMT footprint
- Low-profile L2 stacking height minimizes overall mezzanine stack height for space-constrained embedded and industrial PCB designs
- Tape-and-reel (TR) packaging and gold-plated contacts enable reliable automated assembly and long service life in harsh environments
Applications
The SFM-126-L2-STL-D-A-K-TR is designed for high-density board-to-board mezzanine connections in industrial automation, defense electronics, and communications infrastructure equipment. Its 52-position dual-row, 1.27 mm pitch configuration supports high signal-count interfaces between carrier boards and daughter cards. The low-profile stacking height and surface mount footprint make it suitable for thin, ruggedized enclosures where vertical clearance is limited.

Frequently Asked Questions
How many positions does the SFM-126-L2-STL-D-A-K-TR have, and what is its pitch?
The SFM-126-L2-STL-D-A-K-TR has 52 total positions arranged in a dual-row configuration with a 0.050 inch (1.27 mm) pitch. This high-density layout allows 26 contacts per row, supporting a wide range of parallel data bus or mixed signal interfaces on a single compact surface mount connector.
What does the L2 designation in the SFM-126-L2-STL-D-A-K-TR part number indicate about the connector's stacking height?
The L2 suffix specifies the low-profile stacking height option in SAMTEC's SFM series. This shorter mated stack height compared to standard variants is critical in applications where the total board-to-board clearance is constrained to less than 10 mm, such as in embedded computing modules, compact medical devices, or stacked PCB assemblies in 1U rack equipment.
Is the SFM-126-L2-STL-D-A-K-TR compatible with SAMTEC SFM series mating connectors, and what are the procurement lead times?
Yes, the SFM-126-L2-STL-D-A-K-TR mates with SAMTEC's corresponding SFM series plug strips of matching 52 positions and 1.27 mm pitch. SAMTEC typically stocks SFM series parts for same-day or next-day shipment, and the tape-and-reel packaging with 52-position count supports procurement of 500 to 2000+ pieces per reel for volume production runs.
