Key Features
- Tiger Eye beryllium copper contacts with 30 µin gold mating finish providing superior contact reliability over thousands of mating cycles
- 20-position dual-row 0.050" (1.27 mm) pitch SMT socket enabling high-density board-to-board interconnects in compact layouts
- Tape-and-reel (TR) packaging with polarization key for automated pick-and-place assembly and mis-mating prevention
Applications
The SFM-110-02-S-D-P-TR is used in dense board-to-board and mezzanine connector applications where 20 dual-row positions at 0.050" pitch are required with high-cycle reliability. It suits computing module stacks, industrial control daughtercards, test and measurement equipment, and high-reliability communications boards that require robust mating over hundreds of plug-and-unplug cycles. The 30 µin gold finish and Tiger Eye contact geometry make it appropriate for designs that demand low and stable contact resistance in demanding electrical environments.

Frequently Asked Questions
What contact finish does SFM-110-02-S-D-P-TR use, and how many mating cycles does the 30 µin gold plating support?
The SFM-110-02-S-D-P-TR uses 30 µin (0.76 µm) gold over nickel on the mating interface of its beryllium copper Tiger Eye contacts, with tin over nickel on the termination side. The 30 µin gold mating finish is rated for a high number of mating cycles — Samtec's SFM series with this finish typically supports 500 or more mating cycles while maintaining contact resistance below specified limits, making it suitable for removable module applications in test fixtures and field-replaceable computing boards.
How does the dual-row 0.050" pitch layout of SFM-110-02-S-D-P-TR compare to a 0.100" pitch alternative for a 20-position interconnect?
A dual-row 20-position connector at 0.050" (1.27 mm) pitch occupies roughly one-quarter the board footprint of a 0.100" pitch equivalent carrying the same 20 signals. The SFM-110-02-S-D-P-TR achieves this density in an SMT package that can be placed alongside other fine-pitch SMD components, enabling compact board-to-board stack designs in products where a 0.100" pitch connector would consume too much PCB real estate.
For which design scenarios is the polarization feature on SFM-110-02-S-D-P-TR most critical?
The polarization key on SFM-110-02-S-D-P-TR prevents the mating plug from being inserted in the wrong orientation, which is critical in dual-row 20-position connectors where a 180-degree mis-insertion would connect power pins to signal pins or reverse power polarity. This is especially important in field-serviceable rack modules, lab instruments, and RF boards where technicians may replace daughtercards without consulting a schematic, and a mis-mated 20-pin connection could damage components rated at 3.3 V or 5 V logic levels.
