Key Features
- 54-position dual-row right-angle (STL) socket strip with 0.050-inch (1.27 mm) pitch providing 108 gold-plated contacts
- Right-angle lead style enables horizontal mating orientation, reducing stacked board height versus vertical alternatives
- Gold-plated contacts rated for 1 A per pin with contact resistance below 20 mΩ maintained across 500+ mating cycles
- Tape-and-reel packaging supporting high-volume automated pick-and-place SMT assembly at reflow temperatures up to 260°C
Applications
The SFM-127-L2-STL-D-A-K-TR is used in horizontal edge-mount and right-angle board-to-board interconnect applications where vertical stack height must be minimized, such as compact embedded computing modules, medical wearable sensor hubs, and ruggedized avionics panel electronics. Its 108-contact right-angle configuration supports high-density signal routing along the PCB edge at 1.27 mm pitch. Industrial data acquisition cards and RF front-end modules requiring horizontal mezzanine access also benefit from its low-profile SMT right-angle design.

Frequently Asked Questions
What is the lead style of the SFM-127-L2-STL-D-A-K-TR, and how does it affect board stack height?
The SFM-127-L2-STL-D-A-K-TR uses a right-angle (STL) lead style, orienting the mating axis parallel to the PCB surface rather than perpendicular. This lowers the mated stack height compared to vertical socket strips, enabling compact enclosures where board-to-board clearance is limited to less than 5 mm in embedded computing and medical wearable designs.
How many total contacts does the SFM-127-L2-STL-D-A-K-TR provide at what pitch?
The SFM-127-L2-STL-D-A-K-TR provides 108 total contacts in a 54-position dual-row layout at 0.050-inch (1.27 mm) pitch. This density accommodates parallel 32-bit or 48-bit data buses plus power and ground lines in a single right-angle SMT connector, minimizing the PCB real estate needed for high-speed interfaces in constrained designs.
What current rating and mating durability does the SFM-127-L2-STL-D-A-K-TR offer?
Each contact is rated for 1 A continuous current, and the SFM-127-L2-STL-D-A-K-TR is qualified for a minimum of 500 mating cycles while maintaining gold-plated contact resistance below 20 mΩ. The connector operates across -55°C to 125°C, making it reliable in thermally cycling industrial automation and avionics applications where extended service life is required.
Is the SFM-127-L2-STL-D-A-K-TR supplied for automated SMT production processes?
Yes, the TR suffix identifies tape-and-reel packaging for automated pick-and-place SMT equipment. The SFM-127-L2-STL-D-A-K-TR supports lead-free reflow soldering at peak temperatures up to 260°C per IPC/JEDEC J-STD-020, complying with RoHS requirements. Its standard 1.27 mm pitch footprint is supported by off-the-shelf PCB land pattern libraries, simplifying integration into high-volume production lines.
