What are the key features of TFC-121-02-L-D-A-K-TR?
- 42-position dual-row 0.050" pitch layout with key (K) alignment feature preventing mis-mating in automated and field assembly operations
- Tiger Eye wiping contact technology ensuring oxide-free, low-resistance connections across repeated mating cycles in compact 1.27 mm pitch footprints
- Tape-and-reel (TR) packaging enabling high-volume automated pick-and-place SMT assembly at production line rates exceeding 1000 parts per hour
What is TFC-121-02-L-D-A-K-TR used for?
The TFC-121-02-L-D-A-K-TR is designed for high-volume consumer electronics, communication sub-modules, and compact industrial controllers where 42 signals must be routed across a board-to-board or module interface in a minimal 0.050" pitch footprint. The key alignment feature prevents mis-mating during automated manufacturing, reducing assembly defect rates in multi-shift production environments. Tape-and-reel packaging ensures seamless integration into SMT pick-and-place lines without the need for manual component handling.
