What are the key features of TSM-125-02-SM-DH-A-K-TR?
- 50-position dual-row 0.100" (2.54 mm) pitch for broad compatibility with standard PCB grid layouts
- Tape-and-reel (TR) packaging enabling high-volume automated pick-and-place assembly
- Gold-plated contacts delivering reliable low-resistance signal connections in demanding environments
- Surface mount dual-height (DH) design providing mechanical flexibility for board stacking applications
What is TSM-125-02-SM-DH-A-K-TR used for?
The TSM-125-02-SM-DH-A-K-TR is used in industrial automation, embedded computing, and telecommunications equipment where a 50-position 0.100" pitch dual-row surface mount terminal strip provides reliable signal and power distribution between boards. Its dual-height feature accommodates varying standoff requirements in board stacking configurations, while the tape-and-reel format streamlines production on automated SMT lines. This connector is also popular in test and measurement fixtures requiring dense, repeatable signal connections across 50 positions.

Frequently Asked Questions
What are the position count and pitch specifications of the TSM-125-02-SM-DH-A-K-TR?
The TSM-125-02-SM-DH-A-K-TR provides 50 positions arranged in a dual row on a 0.100" (2.54 mm) pitch, one of the most widely used PCB grid spacings. This configuration supports routing up to 25 differential signal pairs or 50 single-ended signals across a board interface measuring approximately 63.5 mm in row length.
How does the dual-height (DH) feature of the TSM-125-02-SM-DH-A-K-TR benefit board stacking designs?
The dual-height (DH) designation means the TSM-125-02-SM-DH-A-K-TR is manufactured with an elevated insulator body, typically providing additional clearance of 2 mm to 4 mm between mated boards. This extra standoff accommodates components that extend above the PCB surface while still maintaining a secure 50-position SMT connection in stacked board assemblies.
Is the TSM-125-02-SM-DH-A-K-TR suitable for automated PCB assembly, and what packaging does it use?
Yes, the TSM-125-02-SM-DH-A-K-TR is packaged in tape-and-reel (TR) format, making it fully compatible with standard SMT pick-and-place equipment operating at standard reflow temperatures up to 260°C. The tape-and-reel format also supports high-volume production runs exceeding thousands of units per reel.
When would a designer select TSM-125-02-SM-DH-A-K-TR over a 0.050" pitch SAMTEC SFM connector?
A designer would prefer the TSM-125-02-SM-DH-A-K-TR when using legacy 0.100" (2.54 mm) pitch PCB layouts or when mating with through-hole or standard-pitch headers, whereas the 0.050" pitch SFM series is chosen for newer high-density boards where PCB area must be minimized. The 0.100" pitch also offers greater mechanical robustness for connectors subjected to repeated mating cycles exceeding 100 insertions.
