Key Features
- 86-position dual-row layout at 0.050" (1.27 mm) pitch delivers very high signal density for complex PCB interconnects
- Tiger Eye dual-beam contact design ensures reliable mating and low contact resistance across the full 86-pin array
- Cost-effective construction supports high-volume manufacturing without sacrificing connectivity performance in high-pin-count designs
Applications
The TFC-143-02-LM-D-A-K is engineered for very high-density signal interconnection in advanced embedded computing boards, FPGA development platforms, and telecommunications line cards. Its 86-position dual-row format at 0.050" pitch enables engineers to route a large number of parallel signals within a compact PCB area. This makes it a strong choice for data plane backplanes, high-speed DSP systems, and instrumentation front-ends where space efficiency and reliable 86-channel connectivity are both required.

Frequently Asked Questions
What signal density can the TFC-143-02-LM-D-A-K provide compared to a 0.100" pitch connector?
The TFC-143-02-LM-D-A-K provides 86 signal positions in a dual-row layout at 0.050" (1.27 mm) pitch, achieving roughly twice the signal density of a comparable 0.100" pitch connector along the same board length. This allows designers to route 86 parallel channels in the footprint that a 0.100" pitch connector would use for approximately 43 positions, which is critical in space-limited FPGA boards, backplanes, and high-speed data acquisition systems.
In which system designs is the 86-position count of the TFC-143-02-LM-D-A-K particularly advantageous?
An 86-position count is well suited for FPGA I/O expansion boards, high-channel-count data acquisition front-ends, and telecom line cards that must route many parallel signals between PCBs or daughter cards. The dual-row 0.050" pitch layout of the TFC-143-02-LM-D-A-K keeps the connector footprint compact even at 86 pins, supporting dense backplane designs and multi-function embedded computing modules where board real estate is at a premium.
Does the Tiger Eye contact design in the TFC-143-02-LM-D-A-K support reliable connections under vibration in industrial environments?
Yes. The Tiger Eye dual-beam contact used across all 86 positions provides a wiping action during mating that removes surface oxidation and maintains stable contact resistance, even when exposed to vibration and thermal cycling typical of industrial environments. This geometry supports reliable electrical connection over hundreds of mating cycles, which is important for equipment that undergoes regular maintenance or module replacement.
