Frequently Asked Questions
What is the Tiger Eye contact technology in the SFM-105-02-S-D-A and why does it improve connection reliability?
The Tiger Eye contact in the SFM-105-02-S-D-A is a SAMTEC-proprietary design featuring a dual-beam wiping action that cleans the mating pin surface during insertion. This reduces contact resistance variability in the 10-position dual-row 0.050" (1.27 mm) pitch socket, resulting in more stable electrical performance across thousands of mating cycles compared to single-beam alternatives used in standard SMT socket strips.
How does the positioning pin in the SFM-105-02-S-D-A aid in SMT assembly and reduce placement errors?
The positioning pin is a mechanical feature that inserts into a locating hole in the PCB, aligning the SFM-105-02-S-D-A body precisely before soldering. This prevents rotational or translational misalignment of the 10-position dual-row 0.050" (1.27 mm) pitch contacts during reflow, reducing solder bridging defects and ensuring the connector lands on its correct footprint in automated assembly.
How many positions does the SFM-105-02-S-D-A provide, and what are its body dimensions for PCB layout planning?
The SFM-105-02-S-D-A provides 10 positions in a dual-row arrangement with 5 contacts per row at 0.050" (1.27 mm) pitch. The body measures 0.375" in length, 0.145" in breadth, and 0.190" in depth, making it suitable for compact PCB layouts in space-constrained applications such as miniature sensor modules and small embedded computing boards.
When would an engineer choose the SFM-105-02-S-D-A over a standard non-Tiger Eye socket strip for a 10-position connection?
An engineer would select the SFM-105-02-S-D-A over standard socket strips when the application demands higher contact reliability under vibration or in environments with potential contact oxidation, since the Tiger Eye dual-beam wipe provides a self-cleaning action not found in single-beam contacts. Applications in aerospace avionics, military electronics, and medical devices with 10 signal lines at 1.27 mm pitch benefit most from this high-reliability connector design.
