What are the key features of TSM-122-04-LM-DH-A-K-TR?
- 44-position dual-row surface-mount layout at 0.100" (2.54 mm) pitch provides broad signal routing capacity in a compact SMT footprint
- High-mating-force contact design (-H suffix) ensures positive retention and vibration resistance for board-to-board and cable-to-board assemblies
- Tape-and-reel (-TR) packaging enables high-speed automated pick-and-place assembly at production volumes exceeding thousands of units per reel
What is TSM-122-04-LM-DH-A-K-TR used for?
The TSM-122-04-LM-DH-A-K-TR is suited for SMT backplane signal distribution, embedded controller I/O headers, and modular board-to-board stacking where 44 dual-row positions at 0.100" pitch are required. The high-mating-force variant is particularly valuable in industrial and transportation applications subject to mechanical shock or vibration. Tape-and-reel packaging supports seamless integration into high-volume SMT pick-and-place production lines.

Frequently Asked Questions
How many positions and what pitch does the TSM-122-04-LM-DH-A-K-TR offer?
The TSM-122-04-LM-DH-A-K-TR provides 44 total positions arranged in a dual-row surface-mount configuration at 0.100" (2.54 mm) pitch, delivering high contact density for signal or mixed signal-and-power board-to-board interconnects in compact SMT designs.
Why does the -DH suffix on TSM-122-04-LM-DH-A-K-TR matter for harsh-environment designs?
The -DH suffix designates a dual-row, high-mating-force contact variant. Higher mating force—typically 30–50% greater than standard—improves resistance to unmating under vibration loads of 10 G or more, making this connector appropriate for industrial, automotive, and transportation PCB assemblies.
Is TSM-122-04-LM-DH-A-K-TR compatible with standard 0.100" pitch mating headers for modular board designs?
Yes. The 0.100" (2.54 mm) pitch is the industry-standard spacing used across a wide range of SAMTEC and third-party mating headers. The 44-position dual-row layout mates directly with compatible TSW or TFM series headers, enabling flexible modular board stacking and daughter-card designs without custom tooling.
