Applications
The TFC-129-02-LM-D-A-K-TR suits high-density digital interfaces in embedded computing modules, FPGA development boards, and industrial I/O expansion cards where 58 signal lines must be routed in a minimal PCB footprint. Its 1.27 mm pitch allows placement in space-constrained areas near processor peripherals and memory buses. The tape-and-reel format makes it well-suited for automated assembly in mid- to high-volume production runs.

Frequently Asked Questions
How many positions does the TFC-129-02-LM-D-A-K-TR have, and what pitch spacing do the contacts use?
The TFC-129-02-LM-D-A-K-TR has 58 positions arranged in a dual-row format with 0.050 inch (1.27 mm) pitch between adjacent contacts. This fine pitch enables routing of 58 signal lines in a connector footprint roughly 36 mm long, making it ideal for dense digital bus interfaces on compact PCBs.
What packaging option does the TFC-129-02-LM-D-A-K-TR use, and how does it support high-volume PCB assembly?
The TFC-129-02-LM-D-A-K-TR is supplied in tape-and-reel (TR) format, which is fully compatible with automated SMT pick-and-place equipment. This packaging minimizes manual handling, reduces placement errors, and supports production rates typical of industrial electronics manufacturing lines processing hundreds of boards per hour.
For a 58-signal FPGA expansion interface, why choose the TFC-129-02-LM-D-A-K-TR over a standard 2.54 mm pitch connector?
A 2.54 mm pitch connector would require approximately 73 mm of board edge for 58 positions in a single row, whereas the TFC-129-02-LM-D-A-K-TR fits the same 58 signals in roughly 36 mm at 1.27 mm pitch in a dual-row layout. This halves the board-edge real estate consumption, freeing critical PCB area near FPGA I/O banks.
What contact plating does the SAMTEC Tiger Eye series use, and how does it affect connector reliability in industrial environments?
SAMTEC Tiger Eye contacts use selective gold plating on the mating surfaces, typically 30 µin of gold over nickel underplate. Gold plating resists oxidation and provides stable contact resistance below 20 mΩ even after hundreds of mating cycles, making the connector reliable in industrial environments with temperature cycling from -55°C to +125°C.
