Key Features
- 54-position dual-row layout supports 27 signals per row at 0.050-inch pitch
- Right-angle SMT termination for edge-card and panel-mount signal breakout
- High-reliability gold-plated contacts rated for repeated mating cycles
- Tape-and-reel packaging (-TR) for high-volume automated assembly
Applications
The SFM-127-T2-H-D-K-TR is used in board-to-board and board-to-cable interconnect designs where a right-angle SMT socket minimizes vertical profile in enclosures. Its 54-position dual-row configuration suits FPGA daughter cards, high-density signal breakout boards, and test fixtures. The part is a standard choice for telecommunications, medical instrumentation, and ruggedized computing platforms that require dense, reliable connectors.

Frequently Asked Questions
How does the right-angle orientation of the SFM-127-T2-H-D-K-TR affect PCB layout compared to a vertical SMT socket?
The right-angle termination routes the 54 positions parallel to the PCB surface rather than perpendicular, enabling edge-facing connectors that exit the board horizontally. This reduces the overall system height by avoiding a vertical mating stack, which is critical in enclosures with a height constraint below 10 mm.
What pitch and row count does the SFM-127-T2-H-D-K-TR use, and what mating plug series is compatible?
The SFM-127-T2-H-D-K-TR uses a 0.050-inch (1.27 mm) pitch in a dual-row, 54-position configuration with 27 pins per row. It mates with SAMTEC's SFM or TSM plug series at the same 0.050-inch pitch, providing a secure 54-contact interconnect for high-density signal buses.
For a compact FPGA carrier board, how many signal lanes can be routed through the SFM-127-T2-H-D-K-TR?
The 54-position dual-row socket provides up to 54 independent signal contacts, sufficient for routing 4 high-speed differential pairs, 16 LVDS lines, and several GPIO or power rails simultaneously. At 0.050-inch pitch the full 54-contact footprint spans approximately 1.4 inches, fitting neatly on standard Eurocard or half-size mezzanine boards.
What tape-and-reel format does the -TR suffix indicate for production procurement?
The -TR suffix designates tape-and-reel packaging, meaning the SFM-127-T2-H-D-K-TR ships on a carrier reel compatible with standard SMT pick-and-place machines using 12 mm or 16 mm feed tape. This format supports uninterrupted feeding during high-volume production runs at placement rates exceeding 5,000 components per hour.
