Frequently Asked Questions
What is the Tiger Eye system in the TFC-115-02-L-D-A, and what does it offer for board stacking reliability?
The Tiger Eye system in the TFC-115-02-L-D-A is Samtec's proprietary contact design that uses a cantilever beam geometry to produce a wiping action during mating, ensuring low contact resistance and self-cleaning of the mating interface. Combined with the shrouded housing, this system provides secure retention and polarized mating alignment for the 30-position dual-row connector, making it highly reliable for board stacking in vibration-prone industrial and defense environments.
What contact plating specification does the TFC-115-02-L-D-A use, and why does it matter?
The TFC-115-02-L-D-A uses gold (10 µin minimum) over nickel (50 µin) on the mating contacts and tin-over-nickel on the termination contacts. Gold plating provides corrosion resistance and low contact resistance over hundreds of mating cycles, while the nickel barrier prevents gold diffusion into the base metal. This plating specification ensures stable electrical performance for the 30-position dual-row connector across a wide operating temperature range.
How does the shrouded housing of the TFC-115-02-L-D-A prevent assembly errors in board stacking systems?
The shrouded housing of the TFC-115-02-L-D-A surrounds all 30 dual-row male contacts with a protective wall that guides the mating socket connector into correct alignment and prevents off-center or reversed insertion. This polarized shroud design eliminates mis-mating errors during board assembly or field maintenance, protecting the gold-plated contacts from mechanical damage and reducing rework costs in production environments.
What PCB footprint and body dimensions should engineers expect when designing with the TFC-115-02-L-D-A?
The TFC-115-02-L-D-A has a body length of 1.625 inches (approximately 41.3 mm) and a body breadth of 0.225 inches (approximately 5.7 mm), with the 30-position dual-row contacts arranged at 0.050" (1.27 mm) pitch. Engineers should verify the recommended PCB footprint from Samtec's land pattern data to ensure proper solder joint formation and mechanical alignment with the mating TFC socket connector in a mezzanine stack design.
