What are the key features of SFM-124-T2-LM-D-A-P-TR?
- 48-position dual-row SMT socket at 0.050 inch (1.27 mm) pitch enabling high-density board-to-board interconnect in a minimal PCB footprint
- High-reliability socket strip contact design engineered for extended mating cycle life in demanding embedded computing and module applications
- Low-profile mated height (-LM) variant reducing total PCB stack height for slim mezzanine and daughter-card assemblies
- Tape-and-reel (-TR) packaging supporting fully automated pick-and-place SMT assembly for high-volume production
What is SFM-124-T2-LM-D-A-P-TR used for?
The SFM-124-T2-LM-D-A-P-TR is designed for mezzanine board stacking, daughter-card attachment, and module-to-baseboard interconnect in embedded computing, industrial I/O, and communications equipment. Its 48-position, 0.050-inch pitch footprint accommodates parallel data buses, power, and ground distribution across stacked PCBs within a compact assembly envelope. The high-reliability contact design makes it suitable for applications requiring hundreds of mating cycles, such as removable function modules and field-replaceable PCB assemblies.

Frequently Asked Questions
What is the position count and pitch of the SFM-124-T2-LM-D-A-P-TR, and how does the dual-row layout affect routing density?
The SFM-124-T2-LM-D-A-P-TR provides 48 positions in a dual-row arrangement at 0.050 inch (1.27 mm) pitch, with 24 contacts per row. This layout concentrates 48 signal and power connections into a connector footprint of approximately 31 mm in length, enabling dense routing of parallel data buses and mixed-voltage rails between mated PCBs without consuming excessive board real estate compared to single-row or wider-pitch alternatives.
How does the low-profile mated height (-LM) designation benefit slim embedded module stack designs?
The -LM (low-profile mated) designation means the SFM-124-T2-LM-D-A-P-TR presents a reduced overall mated height above the PCB surface, typically targeting stacking clearances of 2 mm to 4 mm between PCBs. This is critical for embedded modules like COM Express Type 10 or custom SOM designs where the total assembled height from baseboard to mezzanine top surface must remain under 10 mm, allowing the system to fit into slim enclosures or meet thermal management spacing requirements.
With which SAMTEC pin header series does the SFM-124-T2-LM-D-A-P-TR mate, and what mating cycle rating can engineers design to?
The SFM-124 socket strip is designed to mate with SAMTEC's corresponding SFM-series pin headers at 0.050 inch pitch, forming a matched board-to-board interconnect system. SAMTEC rates SFM-series high-reliability socket strips for a minimum of 200 mating cycles under standard conditions, with contact resistance typically remaining below 30 milliohms across the rated cycle life, making the combination suitable for removable module and field-serviceable PCB applications.
What procurement advantages does the tape-and-reel packaging of the SFM-124-T2-LM-D-A-P-TR offer versus tube-packaged connectors?
Tape-and-reel packaging for the SFM-124-T2-LM-D-A-P-TR allows direct loading into SMT pick-and-place machines without manual re-taping or feeder modification, reducing placement setup time by typically 15 to 30 minutes per component changeover on a production line. Standard reel quantities are typically 500 to 1,000 pieces per reel, lowering per-unit handling cost in high-volume runs. Cut-tape quantities for prototyping are available through SAMTEC's distribution partners with minimum order quantities as low as 1 piece.
