Key Features
- 52-position dual-row surface mount terminal strip with 2.54 mm pitch for high-density board-level signal distribution
- Low-profile SMT design enabling placement in space-constrained PCB assemblies while maintaining mechanical stability under reflow conditions
- Dual-height (DH) configuration allowing compatibility with both standard and elevated mating connector profiles in backplane and daughtercard designs
Applications
The TSM-126-02-L-DH-A-K-TR is used in communications backplanes, industrial control cards, and test and measurement equipment requiring 52-position surface mount terminal strip connectivity at standard 0.1-inch pitch. Its dual-height configuration supports mating with various connector heights in stacked board assemblies. The SMT footprint enables automated pick-and-place assembly for efficient high-volume PCB manufacturing.

Frequently Asked Questions
What position count and pitch does TSM-126-02-L-DH-A-K-TR offer, and how is it arranged?
The TSM-126-02-L-DH-A-K-TR provides 52 total positions arranged in a dual-row layout with 26 positions per row at a 2.54 mm (0.100 inch) pitch. This standard spacing is compatible with 0.1-inch grid PCBs used in industrial control, communications, and test equipment where high signal channel density is required.
What does the dual-height (DH) designation mean for TSM-126-02-L-DH-A-K-TR in a stacked PCB design?
The dual-height designation indicates the TSM-126-02-L-DH-A-K-TR supports two mating stack heights, typically 8.5 mm and 11.5 mm above the PCB surface, allowing designers to choose the appropriate board-to-board standoff height for their assembly. This flexibility suits both compact stacked modules and larger daughtercard applications with 52 signal positions.
How does TSM-126-02-L-DH-A-K-TR compare to a through-hole 52-position terminal strip for high-volume SMT assembly?
The SMT configuration of TSM-126-02-L-DH-A-K-TR eliminates the need for PCB drilling, reducing board fabrication cost by approximately 5% to 15% on high-density designs with 52 or more positions. It is compatible with standard reflow ovens at peak temperatures up to 260°C and automated pick-and-place machines, enabling production rates of 1000 or more boards per hour compared to manual through-hole insertion.
