What are the key features of SFM-129-T2-STL-D-K-TR?
- 58-position dual-row layout on 0.050" (1.27 mm) pitch maximizes signal density for compact mezzanine connections
- Integrated stiffener (STL) option adds mechanical rigidity to the socket strip body, reducing flex-induced contact stress
- Tape-and-reel (TR) packaging with gold-plated contacts supports automated assembly and long-life mating reliability
What is SFM-129-T2-STL-D-K-TR used for?
The SFM-129-T2-STL-D-K-TR is designed for high-density mezzanine and board-to-board interconnect applications in embedded computing, communications, and medical instrumentation. The integrated stiffener enhances mechanical stability when mating and unmating the 58-position dual-row connector in systems subject to vibration or repeated insertion cycles. Surface mount construction and tape-and-reel packaging support high-volume automated pick-and-place assembly in production environments.

Frequently Asked Questions
What does the STL designation mean in the SFM-129-T2-STL-D-K-TR part number?
The STL suffix indicates an integrated stiffener added to the SFM-129 socket strip body. This stiffener provides additional mechanical rigidity across the 58-position dual-row connector length, reducing contact stress caused by PCB flexing or repeated mating cycles and helping maintain consistent 0.050-inch pitch alignment over the product lifetime.
For a vibration-prone industrial enclosure, how does the SFM-129-T2-STL-D-K-TR outperform a non-stiffened socket strip?
In vibration-prone environments, the stiffener in the SFM-129-T2-STL-D-K-TR keeps the 58-position dual-row body from bowing or twisting under mechanical stress, preserving the 0.050-inch pitch alignment and gold-plated contact integrity. Non-stiffened alternatives can flex under repeated vibration, increasing contact resistance and risk of intermittent signal loss on critical interfaces.
How many signals can the SFM-129-T2-STL-D-K-TR route across a mezzanine interface, and what is its pitch?
The SFM-129-T2-STL-D-K-TR routes 58 independent signals across a mezzanine interface using a dual-row arrangement on a 0.050-inch (1.27 mm) pitch. Its compact footprint accommodates 58 signals in roughly half the board length of an equivalent 0.100-inch pitch connector, making it well suited for space-constrained embedded and communications PCBs.
