What are the key features of SFM-120-T2-LM-D-A-P-TR?
- 40 contacts in 2 rows at 0.050" (1.27 mm) pitch for reliable high-density mezzanine and board-to-board interconnect
- Low-profile (LM) housing reduces board stack height, optimizing vertical clearance in space-constrained assemblies
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT reflow assembly for high-volume production
What is SFM-120-T2-LM-D-A-P-TR used for?
The SFM-120-T2-LM-D-A-P-TR is suited for compact embedded computing modules, industrial sensor interfaces, and portable instrument boards requiring a low-profile 40-position dual-row connector at 1.27 mm pitch. Its LM (low-profile) housing minimizes mezzanine stack height, which is important in slim enclosures and compact chassis designs. The SMT format combined with tape-and-reel packaging ensures efficient automated assembly in volume manufacturing.

Frequently Asked Questions
How many positions and rows does SFM-120-T2-LM-D-A-P-TR provide at its rated pitch?
The SFM-120-T2-LM-D-A-P-TR offers 40 positions across 2 rows at a 0.050 inch (1.27 mm) pitch. This configuration supports parallel data buses, mixed-signal lines, and I/O expansion on a compact SMT footprint, suitable for embedded computing daughter cards and mezzanine modules in industrial and instrumentation systems.
What is the significance of the LM (low-profile) designator in SFM-120-T2-LM-D-A-P-TR for slim enclosure designs?
The LM designation means the SFM-120-T2-LM-D-A-P-TR has a reduced housing height compared to standard or tall-profile SFM variants at the same 1.27 mm pitch. In slim enclosures, portable instruments, or wearable platforms where total PCB stack height must stay below a few millimeters, the low-profile housing directly determines whether the mezzanine board fits within the available Z-axis clearance.
For a portable sensor board, how does the 40-position SFM-120-T2-LM-D-A-P-TR compare to a higher pin-count variant?
At 40 positions the SFM-120-T2-LM-D-A-P-TR balances contact density with connector body length at 1.27 mm pitch. Compared to 56-position or 92-position SFM variants, it occupies less board length, reducing PCB cost and routing complexity for sensor boards with modest bus widths. If the design carries 8-bit ADC data, SPI, and auxiliary signals, 40 positions typically provides sufficient contacts without excess unused pins.
Can SFM-120-T2-LM-D-A-P-TR be wave-soldered or is it exclusively for reflow?
The SFM-120-T2-LM-D-A-P-TR uses SMT surface mount termination pads designed for reflow soldering at the standard 1.27 mm pitch footprint. Wave soldering is not recommended for SMT connectors because the solder wave can flood fine-pitch pads and cause bridging across the 40-position interface. Automated reflow with pick-and-place placement from the tape-and-reel carrier is the intended assembly method.
