Key Features
- 8-position dual-row female socket at 1.27 mm (0.050 inch) pitch for compact high-density board-to-board mating in minimal PCB area
- High-reliability socket strip construction rated for over 1000 mating cycles with consistent contact resistance below 20 mΩ
- Anti-misalignment keying (K suffix) prevents incorrect mating and protects signal integrity in automated assembly environments
Applications
The SFM-104-02-H-D-A-K is used in compact board-to-board interconnect applications including daughter card attachment on embedded processor modules, sensor interface boards, and miniature industrial controllers where 8 dual-row contacts at 1.27 mm pitch must fit within a 10 mm x 5 mm footprint. Its high-reliability socket design supports frequent mating and unmating in field-serviceable equipment and test fixture applications requiring repeatable electrical connections.

Frequently Asked Questions
How many positions and what pitch does SFM-104-02-H-D-A-K provide for compact interconnects?
SFM-104-02-H-D-A-K provides 8 total positions in a dual-row layout at 1.27 mm (0.050 inch) pitch, giving 4 contacts per row in a compact surface mount footprint suitable for miniature daughter card and sensor module attachments.
In a field-serviceable industrial module design, how does SFM-104-02-H-D-A-K's keying feature prevent mismating?
The K-suffix keying feature adds a mechanical polarization key to the 8-position socket body that physically prevents incorrect orientation during mating, reducing field service errors and protecting signal lines from reverse-insertion damage across 1000+ mating cycles.
What contact resistance can designers expect from SFM-104-02-H-D-A-K in high-cycle test fixture applications?
SAMTEC SFM series high-reliability socket strips maintain contact resistance below 20 mΩ per contact over the rated mating cycle life, making SFM-104-02-H-D-A-K suitable for test fixtures that require stable electrical performance across 1000 or more connection cycles.
How does SFM-104-02-H-D-A-K compare to SFM-145-T2-S-D-A-K when only 8 positions are needed?
When a design requires only 8 signal connections rather than 90, SFM-104-02-H-D-A-K uses a body length of approximately 0.275 inches versus 2.375 inches for SFM-145, saving over 50 mm of PCB length and reducing connector cost by roughly 80% while maintaining the same 1.27 mm pitch and high-reliability socket construction.
