What are the key features of SFM-134-T2-LM-D-K-TR?
- 68-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch supporting ultra-high-density board-to-board interconnects
- High-reliability design with gold-plated contacts maintaining contact resistance below 20 mΩ across extended mating cycles
- K keying feature prevents reversed insertion, protecting all 68 signal channels from misconnection damage
- Tape-and-reel (TR) and LM low-mount options optimized for automated SMT assembly and low-profile stack configurations
What is SFM-134-T2-LM-D-K-TR used for?
The SFM-134-T2-LM-D-K-TR is designed for demanding high-density mezzanine and daughter card interconnect applications in FPGA platforms, high-performance computing, and aerospace instrumentation. Its 68-pin dual-row fine-pitch layout at 0.050" enables significantly higher pin count within the same board footprint compared to 0.100" pitch connectors, making it ideal for data-intensive signal routing in rack-mount systems and SBC designs. The keying and low-mount profile further simplify assembly in height-restricted enclosures.

Frequently Asked Questions
How does the SFM-134-T2-LM-D-K-TR compare to 0.100" pitch connectors in terms of pin density?
By using a 0.050" (1.27 mm) pitch instead of the standard 0.100" (2.54 mm), the SFM-134-T2-LM-D-K-TR achieves roughly 4 times the pin density per unit area. Its 68 positions in a dual-row arrangement occupies approximately half the board length of an equivalent 0.100" pitch connector, which is critical in compact FPGA and computing module designs.
What does the LM suffix indicate about the SFM-134-T2-LM-D-K-TR connector height?
The LM (low mount) designation means the connector body sits close to the PCB surface, reducing the overall stack height between mated boards. This allows daughter card assemblies with minimal clearance, typically enabling board separation of around 4 mm to 8 mm, compared to standard-mount variants that require more vertical space.
For which procurement scenarios should engineers consider the SFM-134-T2-LM-D-K-TR over lower pin-count alternatives?
Engineers should select the 68-position SFM-134-T2-LM-D-K-TR when a single high-density connector must carry 60 or more simultaneous signal channels with less than 20 mΩ contact resistance, avoiding the added cost, board space, and alignment complexity of multiple lower pin-count connectors in parallel on FPGA carrier boards or high-speed computing platforms.
