Frequently Asked Questions
How many positions does the TFC-140-02-LM-D-A-K-TR provide and what is the contact pitch?
The TFC-140-02-LM-D-A-K-TR is an 80-position dual-row terminal strip with a 0.050-inch (1.27 mm) contact pitch, giving 40 contacts per row. This high-density layout allows designers to route 80 signals across a board-to-board interface in a very compact footprint, suitable for FPGA mezzanine cards and multi-channel data acquisition modules where minimizing connector width is critical.
What is Tiger Eye contact technology and how does it benefit the TFC-140-02-LM-D-A-K-TR in repeated mating cycles?
SAMTEC's Tiger Eye contact technology uses a dual-beam wiping contact design that provides reliable electrical connection with low insertion force. For the TFC-140-02-LM-D-A-K-TR's 80 positions at 1.27 mm pitch, this translates to consistent contact resistance and improved durability across multiple mate/unmate cycles, which is important in test-and-measurement systems or field-replaceable modules that are frequently connected and disconnected.
What does the TR suffix on the TFC-140-02-LM-D-A-K-TR mean for SMT production planning?
The TR suffix indicates that the TFC-140-02-LM-D-A-K-TR ships in tape-and-reel format, enabling direct loading into automated SMT pick-and-place machines for high-volume production. This packaging is essential for assembly lines producing board-to-board stacks at 0.050-inch pitch, where manual component placement of an 80-position dual-row connector would be impractical and would risk misalignment of the 1.27 mm pitch contacts.
