Key Features
- 54-pin dual-row layout at 2.54 mm pitch supporting dense signal connectivity on a single SMT footprint
- Surface mount termination style enabling automated reflow soldering and reduced assembly labor versus through-hole alternatives
- Tape-and-reel (TR) packaging for continuous high-volume pick-and-place SMT production runs
Applications
The TSM-127-02-SM-DH-A-K-TR terminal strip is used in test and measurement boards, embedded computing modules, and industrial control backplanes where 54 signals must be accessed through a 2.54 mm pitch SMT interface. Its dual-row configuration reduces connector footprint length while maintaining a standard 0.100" grid compatible with common mating headers.
