What are the key features of TSM-123-02-SS-DH-A-K-TR?
- 46-position dual-row SMT terminal strip with 2.54 mm pitch enabling high-density signal routing on standard 0.1-inch grid PCBs
- Stainless steel contact construction providing enhanced durability and corrosion resistance compared to standard tin or gold-plated alternatives
- Surface mount termination compatible with automated reflow assembly at peak temperatures up to 260°C for high-volume manufacturing
What is TSM-123-02-SS-DH-A-K-TR used for?
The TSM-123-02-SS-DH-A-K-TR is used in industrial automation controllers, telecom line cards, and test equipment backplanes requiring 46-position surface mount terminal strip connections with robust contact material. Its dual-row 2.54 mm pitch layout suits high-density PCB designs where through-hole connectors would consume excessive board space. The stainless steel contact version extends service life in environments with elevated humidity or chemical exposure.

Frequently Asked Questions
How many positions does the TSM-123-02-SS-DH-A-K-TR provide, and how are they arranged?
The TSM-123-02-SS-DH-A-K-TR provides 46 total positions arranged in a dual-row configuration with 23 positions per row at a 2.54 mm (0.100 inch) pitch. This layout is compatible with standard PCB grid spacing used in industrial control and communications equipment backplanes requiring high-density signal routing.
Why would a designer choose the stainless steel contact variant of TSM-123-02-SS-DH-A-K-TR over a standard tin contact version?
Stainless steel contacts in TSM-123-02-SS-DH-A-K-TR provide superior corrosion resistance and mechanical durability compared to tin-plated contacts, making them suitable for industrial environments with humidity above 85% RH or exposure to mild chemicals. The SS variant also offers higher tensile strength, reducing contact deformation risk in applications subject to vibration or repeated mating cycles exceeding 50 insertions.
Can TSM-123-02-SS-DH-A-K-TR be processed through standard SMT reflow soldering lines?
Yes, the TSM-123-02-SS-DH-A-K-TR is designed for surface mount reflow soldering with peak temperatures up to 260°C compatible with SAC305 lead-free solder profiles per IPC/JEDEC J-STD-020. The SMT footprint supports automated pick-and-place assembly for production volumes of 500 or more units, reducing per-unit assembly cost compared to through-hole connector alternatives.
