What are the key features of TSM-125-04-TL-DH-A-K-TR?
- 50-position dual-row layout at 0.100" (2.54 mm) standard pitch supports versatile SMD board-to-board and wire-to-board connections
- Top-loaded (TL) contact design allows contacts to be inserted from the top after housing placement, enabling flexible assembly sequencing
- Gold-plated contacts (K) ensure low and stable contact resistance for reliable signal connections across industrial temperature ranges
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for efficient high-volume PCB manufacturing
What is TSM-125-04-TL-DH-A-K-TR used for?
The TSM-125-04-TL-DH-A-K-TR is well-suited for module-to-backplane and daughter-card interconnections in industrial control systems, embedded computing platforms, and test and measurement equipment where 50 contacts at the standard 0.100" pitch are required. The top-loaded contact configuration offers assembly flexibility for builds where connectors must be populated after other board components, making it useful in complex multi-board system architectures. Its gold-plated contacts and tape-and-reel packaging support reliable, production-scale automated SMT assembly for industrial and commercial electronics applications.

Frequently Asked Questions
How many pins per row does the TSM-125-04-TL-DH-A-K-TR have in its dual-row layout?
The TSM-125-04-TL-DH-A-K-TR has 50 total positions in a dual-row (DH) format with 25 pins per row, spaced at 0.100" (2.54 mm) pitch. This standard pitch and dual-row arrangement makes it compatible with a wide range of 0.100" mating connectors and PCB footprints used in industrial control and embedded computing designs.
What does the top-loaded (TL) contact designation mean for assembly of the TSM-125-04-TL-DH-A-K-TR?
The TL (top-loaded) designation means the electrical contacts are inserted into the connector housing from the top after the housing is placed on the PCB, rather than being pre-installed. This allows the 50-position, 0.100" pitch housing to be placed and soldered first, then contacts are loaded, which benefits complex multi-step assembly processes where contact insertion must occur after initial board population.
Why specify gold-plated contacts on the TSM-125-04-TL-DH-A-K-TR over tin-plated alternatives for industrial applications?
Gold-plated contacts (K suffix) on the TSM-125-04-TL-DH-A-K-TR maintain stable contact resistance below 20 milliohms even after thousands of mating cycles and resist corrosion in humid or chemically aggressive industrial environments. For low-voltage signal applications at 0.100" pitch, gold plating provides superior long-term reliability compared to tin contacts that can develop oxide layers increasing contact resistance over time.
Is the TSM-125-04-TL-DH-A-K-TR a good fit for automated SMT production and what is the packaging format?
Yes, the TR suffix confirms tape-and-reel packaging that is directly compatible with automated pick-and-place machines. The 50-position surface-mount format with 0.100" dual-row pitch supports standard reflow solder assembly, making this SAMTEC connector appropriate for high-volume automated SMT production lines in industrial electronics, telecommunications equipment, and embedded computing manufacturing.
