What are the key features of SFM-125-L2-FM-D-A-K-TR?
- 50-position dual-row layout on 0.050 inch (1.27 mm) pitch enabling very high contact density in a minimal PCB area
- High-reliability socket design rated for extended mating cycles with gold-plated contacts ensuring consistent low-resistance connections
- Tape-and-reel (TR) packaging for seamless integration into automated high-volume SMT production lines
What is SFM-125-L2-FM-D-A-K-TR used for?
The SFM-125-L2-FM-D-A-K-TR is used in high-density board-to-board and mezzanine connector applications where 50 contacts must fit within a 0.050-inch pitch footprint. Its high-reliability rating makes it suitable for aerospace, defense, and industrial electronics requiring consistent signal integrity over thousands of mating cycles. The surface-mount format supports modern automated PCB assembly processes in compact, multi-layer board designs.

Frequently Asked Questions
What is the contact pitch of the SFM-125-L2-FM-D-A-K-TR and how does it compare to standard 0.100-inch connectors?
The SFM-125-L2-FM-D-A-K-TR uses a 0.050-inch (1.27 mm) pitch, which is half the spacing of standard 0.100-inch connectors. This finer pitch allows 50 dual-row contacts to occupy roughly the same PCB length as a 25-position 0.100-inch strip, making it ideal for space-constrained high-density designs.
For which reliability-demanding applications is the SFM-125-L2-FM-D-A-K-TR specifically rated?
The SFM series is SAMTEC's high-reliability socket strip line, designed to withstand mating cycles exceeding 500 insertions while maintaining contact resistance below 20 milliohms. It is used in aerospace avionics, military electronics, and industrial instrumentation where connector failure is not acceptable over the product lifetime.
Does the SFM-125-L2-FM-D-A-K-TR support tape-and-reel delivery, and what does this mean for production quantities?
Yes, the TR suffix confirms tape-and-reel packaging, which is compatible with automated SMT pick-and-place machines handling 0.050-inch pitch components. Reels typically contain 500 to 1000 pieces, supporting medium-to-high production volumes while reducing manual placement errors and setup time.
What mating connector from SAMTEC is designed to pair with the SFM-125-L2-FM-D-A-K-TR in a board-to-board stack?
The SFM series female socket strips mate with SAMTEC SHF or SFM-compatible male header strips sharing the same 0.050-inch pitch and 50-position dual-row layout. A typical board-to-board stack height ranges from 4 mm to 20 mm depending on the selected header pin length and standoff configuration.
