Key Features
- 48-position dual-row SMT configuration at 0.050 inch (1.27 mm) pitch for dense board-to-board signal interconnect
- Tape-and-reel (TR) packaging supporting high-volume automated pick-and-place and reflow soldering
- High-reliability contact geometry maintaining consistent electrical performance over thousands of mating cycles
- T2 lead style and SM surface-mount termination optimised for low-profile mezzanine card assembly
Applications
The SFM-124-T2-SM-D-A-K-TR is used in mezzanine and daughter-card stacking applications for embedded computing, industrial automation, and defence electronics where 48 signals at 0.050 inch pitch must be reliably connected between SMT boards. Its tape-and-reel form factor integrates directly into automated assembly lines, making it a cost-effective choice for medium-to-high volume production of control modules and signal acquisition cards.

Frequently Asked Questions
How many positions does SFM-124-T2-SM-D-A-K-TR provide and how are they arranged?
The SFM-124-T2-SM-D-A-K-TR provides 48 positions arranged in 2 rows of 24 contacts each at 0.050 inch (1.27 mm) pitch. This dual-row layout efficiently routes 48 independent signals across a board-to-board interface while keeping the connector length to approximately 30.5 mm, which is useful in compact embedded system designs.
What soldering process is compatible with the SFM-124-T2-SM-D-A-K-TR for production assembly?
The SFM-124-T2-SM-D-A-K-TR uses surface-mount (SM) termination compatible with standard IR or convection reflow soldering at typical peak temperatures of 260°C. Supplied on tape-and-reel, it is fully compatible with automated pick-and-place equipment, enabling throughputs of thousands of placements per hour in a production SMT line.
How does SFM-124-T2-SM-D-A-K-TR compare to a 48-position through-hole socket strip for a mezzanine design?
The SMT SFM-124-T2-SM-D-A-K-TR eliminates drilling, wave-soldering, and manual insertion steps required for through-hole equivalents. At 0.050 inch pitch for 48 pins it occupies roughly 30.5 mm of board length versus approximately 48 mm for a 0.100 inch pitch through-hole strip, reducing connector footprint by about 36% and enabling denser component placement on adjacent layers.
Which industries use SFM-124-T2-SM-D-A-K-TR in their board-to-board interconnect systems?
Industrial control, test-and-measurement, and defence avionics applications rely on SFM series sockets for their high-reliability mating characteristics. For instance, a 48-channel data-acquisition daughter card rated for operation from -40°C to +85°C would use SFM-124-T2-SM-D-A-K-TR to maintain stable contact resistance below 50 mΩ throughout the full temperature range.
