What are the key features of TSM-125-01-LM-DH-A-K-TR?
- 50-position dual-row configuration at 0.100" (2.54 mm) pitch supporting high pin-count signal and power distribution in a compact SMT footprint
- Gold-plated contacts providing low contact resistance and corrosion protection for long-term reliability in harsh environments
- Surface-mount termination enabling automated SMT reflow assembly and precise placement repeatability on high-density PCBs
What is TSM-125-01-LM-DH-A-K-TR used for?
The TSM-125-01-LM-DH-A-K-TR is well-suited for bus interconnect, backplane, and daughter card applications in industrial automation, embedded computing, and test-and-measurement equipment where 50 positions at 2.54 mm pitch are needed. Its surface-mount design streamlines assembly on high-volume production lines without the need for through-hole tooling or manual insertion. This terminal strip also supports signal routing in power supply modules and communication equipment requiring high-density header interfaces.

Frequently Asked Questions
What is the pitch and total position count of the TSM-125-01-LM-DH-A-K-TR?
The TSM-125-01-LM-DH-A-K-TR is a 50-position dual-row surface-mount terminal strip with a 0.100 inch (2.54 mm) pitch. This standard pitch ensures compatibility with common 0.100 inch pitch mating headers and breadboard prototyping systems used across industrial and commercial electronics.
For which PCB assembly methods is the TSM-125-01-LM-DH-A-K-TR optimized?
This connector is optimized for surface-mount technology (SMT) reflow soldering, making it suitable for automated pick-and-place assembly on standard PCB production lines. The SMT termination eliminates the need for through-hole drilling and wave soldering, reducing manufacturing cost when producing boards with 50-position connector requirements.
How does TSM-125-01-LM-DH-A-K-TR compare to a through-hole version for a high-vibration industrial application?
For high-vibration industrial environments, through-hole connectors typically offer superior mechanical retention because solder joints penetrate the PCB. The TSM-125-01-LM-DH-A-K-TR's surface-mount design with 50 positions at 2.54 mm pitch may require underfill or additional mechanical support (such as locking hardware) to meet vibration specifications above 5 g continuous in demanding applications.
What alternative SAMTEC parts should be evaluated if fewer than 50 positions are needed?
If your design requires fewer than 50 positions at 2.54 mm pitch, SAMTEC offers the TSM series in variants such as TSM-110 (20 positions), TSM-115 (30 positions), and TSM-120 (40 positions), allowing engineers to right-size the connector and reduce PCB footprint while maintaining the same 0.100 inch pitch interface and SMT assembly process.
