Frequently Asked Questions
What makes the Tiger Eye contact design in SFM-120-02-S-D-LC-TR superior to standard stamped contacts for high-cycle applications?
Tiger Eye contacts use a dual-beam beryllium copper design that creates two independent contact points per pin, delivering a higher and more consistent normal force than single-beam stamped contacts. This results in reliable electrical performance at contact resistance below 20 milliohms even after thousands of mating cycles, making the SFM-120-02-S-D-LC-TR ideal for field-replaceable modules and test sockets.
What is the gold plating thickness on SFM-120-02-S-D-LC-TR contacts, and why does it matter for reliability?
The mating surface on each of the 40 positions is finished with 30 µin (approximately 0.76 µm) of hard gold over a nickel barrier. This thickness resists fretting corrosion during vibration exposure and maintains low contact resistance over the connector's rated operating temperature range of -55°C to +125°C, meeting the durability standards required by aerospace and defense system qualification programs.
For a compact mezzanine board design, how much board area does the 40-position SFM-120-02-S-D-LC-TR require?
At 0.050" (1.27 mm) pitch in a dual-row arrangement, the 20-position-per-row SFM-120-02-S-D-LC-TR spans approximately 24.4 mm in length and under 4 mm in width for the socket body alone. This compact footprint allows mezzanine cards to use multiple connectors along one PCB edge while keeping the overall board area well within standard 3U or PC/104 form factor constraints.
How does the LC contact length option affect SFM-120-02-S-D-LC-TR's compatibility with mating header pin lengths?
The LC designation selects a specific contact length that controls the mating depth and over-travel allowance when paired with Samtec's SMM or TSM mating headers. Using the correct LC length ensures that pin insertion reaches the dual Tiger Eye beam contact zone, achieving rated normal force and full 30 µin gold contact engagement, rather than bottoming out on the housing before full electrical connection is made.
