What are the key features of SFM-123-T2-LM-D-A-P-TR?
- 46 contacts in 2 rows at 0.050" (1.27 mm) pitch providing high-density signal connectivity in a compact SMT package
- Low-profile (LM) housing minimizes board stack height, critical for slim portable and embedded module designs
- Tape-and-reel (TR) SMT packaging compatible with automated pick-and-place reflow soldering for efficient production
What is SFM-123-T2-LM-D-A-P-TR used for?
The SFM-123-T2-LM-D-A-P-TR targets low-profile mezzanine and daughter card designs in portable industrial computers, medical monitoring devices, and embedded networking modules requiring 46 signal positions at 1.27 mm pitch. The low-profile housing constrains vertical stack height, enabling the connector to fit within enclosures where clearance is limited to a few millimeters. Automated tape-and-reel assembly ensures consistent placement quality across all 46 positions in production.

Frequently Asked Questions
What contact count does SFM-123-T2-LM-D-A-P-TR provide and how is it arranged?
The SFM-123-T2-LM-D-A-P-TR provides 46 contacts arranged in 2 rows at a 0.050 inch (1.27 mm) pitch. This dual-row configuration supports data buses, control lines, and auxiliary signals on a single connector footprint, making it a compact solution for mezzanine stack-ups and daughter card interfaces in embedded and portable hardware designs.
How does the LM low-profile variant of SFM-123-T2-LM-D-A-P-TR benefit portable medical monitor designs?
In portable medical monitors where total PCB stack height must fit within a thin enclosure, the LM (low-profile) housing of the SFM-123-T2-LM-D-A-P-TR reduces the Z-axis clearance required for the mezzanine connection. This allows designers to fit an additional PCB layer or a battery module in the saved space while maintaining reliable 46-position signal connectivity at 1.27 mm pitch through the device's operational temperature range.
When should a designer choose SFM-123-T2-LM-D-A-P-TR over the SFM-120-T2-LM-D-A-P-TR?
Choose the SFM-123-T2-LM-D-A-P-TR over SFM-120 when the design requires 46 rather than 40 contact positions at 1.27 mm pitch. The additional 6 positions (3 per row) allow routing of a wider parallel bus, additional power or ground pins, or auxiliary I2C and SPI control lines without adding a second connector. Both variants share the same LM low-profile housing and tape-and-reel packaging for identical assembly processes.
What soldering method is recommended for SFM-123-T2-LM-D-A-P-TR?
The SFM-123-T2-LM-D-A-P-TR is designed for SMT reflow soldering using automated pick-and-place equipment. Its tape-and-reel carrier loads directly into SMT feeders, and the 1.27 mm pitch pad layout solders cleanly in a standard lead-free reflow profile peaking at approximately 260°C. Hand soldering 46 closely spaced SMT pads is possible but risks solder bridges, so automated reflow is strongly recommended for production.
