Key Features
- 52-position dual-row SMT terminal strip with 0.100" (2.54 mm) pitch for high-density board connections
- Gold-plated contacts ensure low contact resistance and long-term reliability in demanding environments
- Tape-and-reel packaging (TR suffix) enables automated pick-and-place assembly for high-volume production
Applications
The TSM-126-01-LM-DH-A-K-TR is well suited for backplane-to-daughtercard interconnects and board stacking applications where a robust 0.100" pitch SMT header is required. Its 52-position dual-row layout supports high pin-count data and power routing in industrial control modules, test and measurement equipment, and embedded computing boards. The tape-and-reel format makes it ideal for automated assembly lines with high throughput requirements.

Frequently Asked Questions
What is the pin count and row configuration of TSM-126-01-LM-DH-A-K-TR?
The TSM-126-01-LM-DH-A-K-TR features 52 total positions arranged in a dual-row layout on a 0.100" (2.54 mm) centerline pitch. Each row contains 26 pins, providing a compact footprint while delivering high contact density for backplane and stacking interconnect applications.
For automated SMT production lines, how is TSM-126-01-LM-DH-A-K-TR packaged?
This part ships in tape-and-reel format (TR suffix), fully compatible with automated pick-and-place equipment. The reel packaging supports high-volume PCB assembly and reduces handling time. The SMT mounting style allows reflow soldering, which further streamlines production for industrial and computing board manufacturers.
How does the gold plating on TSM-126-01-LM-DH-A-K-TR contacts compare to tin-plated alternatives?
Gold-plated contacts (K suffix) on the TSM-126-01-LM-DH-A-K-TR maintain contact resistance well below 20 mΩ over thousands of mating cycles, outperforming standard tin finishes in humid or vibration-prone environments. Gold resists oxidation, making these 52-pin connectors preferable for high-reliability industrial or aerospace-adjacent applications.
