Frequently Asked Questions
How many positions does the SFM-120-02-L-D-A-K provide and what is its pitch?
The SFM-120-02-L-D-A-K is a dual-row socket connector with 40 total contacts arranged in 2 rows of 20 positions each, at a standard 2.54 mm pitch, making it compatible with common pin header mating connectors used in embedded and industrial PCB designs.
What contact finish is used on the SFM-120-02-L-D-A-K mating surface?
The mating contacts are finished with gold plating (10 µin minimum) to ensure low contact resistance, corrosion resistance, and reliable electrical performance over many thousands of mating cycles in demanding environments.
What is the Tiger Eye contact feature on the SFM-120-02-L-D-A-K and why does it matter?
Tiger Eye is SAMTEC's proprietary contact design that provides a controlled, low insertion force during mating while maintaining a secure 360-degree wrap-around grip on pins. This translates to reliable electrical contact even under vibration, an important factor in industrial and aerospace applications requiring MIL-grade robustness.
In which PCB assembly processes does the SFM-120-02-L-D-A-K positioning pin help?
The positioning pin mechanically aligns the connector to the PCB footprint before soldering, reducing misalignment risk in automated pick-and-place and wave-solder processes. This feature is particularly valuable in high-volume production runs where manual alignment is impractical.
