What are the key features of SFM-127-02-STL-D-A-K-TR?
- 54-position dual-row SMT socket strip at 0.050 inch (1.27 mm) pitch enabling high-density board-to-board signal connections in a minimal PCB footprint
- STL (surface mount low-profile) body combined with K keying option ensures correct mating orientation and reduced stack height for compact multi-board assemblies
- Gold-plated (A) contacts with tape-and-reel (TR) packaging delivering low contact resistance and automated assembly support for high-volume production
What is SFM-127-02-STL-D-A-K-TR used for?
The SFM-127-02-STL-D-A-K-TR is used in FPGA mezzanine expansion boards, compact industrial sensor modules, and wireless communication daughterboards where 54 dual-row signals are required at 0.050 inch pitch. Its keyed low-profile SMT design makes it ideal for multi-board assemblies in portable instruments and medical devices where board height and mating accuracy are critical constraints.

Frequently Asked Questions
How dense is SFM-127-02-STL-D-A-K-TR for a mezzanine socket connection?
SFM-127-02-STL-D-A-K-TR provides 54 pins on a 0.050 inch pitch, so it supports compact dual-row board-to-board interconnects where a low-profile socket strip is needed.
Which mechanical options in this MPN should be matched to the PCB footprint?
The STL low-profile body, D dual-row layout, A alignment option, K keying, and TR tape-and-reel supply should be checked against the 54-position PCB footprint and mating header.
Why specify the keyed version for production assemblies?
The K keying option helps reduce mismating risk on a 54-contact, 0.050 inch socket pair, which is useful when multiple similar mezzanine connectors appear on one board.
