What are the key features of SFM-123-02-LM-D-A-P-TR?
- 46-position dual-row socket at 0.050" (1.27 mm) pitch for high-density signal routing in a compact SMT footprint
- Low-mount (LM) profile minimizing above-board height for tight board-to-board stack assemblies
- Tape-and-reel (TR) packaging enabling seamless automated pick-and-place PCB assembly in volume production
- High-reliability contact construction rated for repeated mating cycles in industrial and computing applications
What is SFM-123-02-LM-D-A-P-TR used for?
The SFM-123-02-LM-D-A-P-TR is ideal for embedded computing mezzanine cards, FPGA daughter-board sockets, and modular industrial control interfaces where 46 positions at 1.27 mm pitch are required in a low-profile surface-mount package. Its low-mount design reduces PCB-to-PCB separation, making it well suited for multi-board assemblies in portable instruments and compact telecom equipment. Tape-and-reel delivery supports high-volume automated PCB manufacturing programs.

Frequently Asked Questions
What does the LM (low-mount) designation mean for the SFM-123-02-LM-D-A-P-TR board stack height?
The LM (low-mount) designation indicates a reduced above-board profile compared to standard height SFM variants. For the 46-position, 1.27 mm pitch SFM-123-02-LM-D-A-P-TR, this lowers the board-to-board separation in mated assemblies — typically achieving a reduced stack height below 5 mm — benefiting portable instruments and slim multi-board embedded enclosures.
How many signal connections does the SFM-123-02-LM-D-A-P-TR support in a single connector pair?
The SFM-123-02-LM-D-A-P-TR provides 46 positions in a dual-row configuration at 0.050 inch (1.27 mm) pitch, enabling up to 46 simultaneous signal, mixed-signal, or power connections across the two rows in a compact surface-mount footprint suitable for high-density board-to-board interface designs.
Which automated assembly processes is the SFM-123-02-LM-D-A-P-TR compatible with?
The SFM-123-02-LM-D-A-P-TR is packaged in tape-and-reel (TR) format and designed for surface-mount reflow soldering at peak temperatures up to 260 °C, making it fully compatible with automated pick-and-place equipment and standard SMT reflow ovens used in high-volume 46-position dual-row connector PCB assembly.
For which embedded computing applications is the SFM-123-02-LM-D-A-P-TR a suitable choice?
This 46-pin, 1.27 mm pitch dual-row low-mount socket is well suited for FPGA mezzanine interfaces, small form factor single-board computers, industrial Ethernet daughter cards, and compact data acquisition modules requiring reliable surface-mount board-to-board connectivity with a minimized height profile.
