What are the key features of TFC-139-02-LM-D-A-K?
- 78 positions at 0.050" (1.27 mm) pitch in a dual-row arrangement provides high contact density for compact PCB designs
- Long machined (-LM) tails enable precise through-hole placement and support wire-wrap or press-fit termination options
- Kinked tail (-K) design ensures positive PCB registration and prevents connector shift during automated assembly processes
What is TFC-139-02-LM-D-A-K used for?
The TFC-139-02-LM-D-A-K serves high-density through-hole interconnection needs on embedded computing cards, industrial controller boards, and data acquisition modules routing 78 signals in a 1.27 mm dual-row footprint. Long machined tails provide extra insertion length for secure solder joints or alternative wire-wrap termination in prototyping environments. The kinked pin design improves alignment in automated PCB assembly, reducing placement defects in volume production.
