Key Features
- 48-position dual-row SMT terminal strip on 2.54 mm pitch, providing 24 pins per row for high pin-count board-to-board interconnects
- Gold-plated contacts rated at 3 A per pin and 250 V AC working voltage ensure reliable mixed signal and power performance
- Top-left (TL) polarization key prevents mis-mating during assembly, reducing rework risk in automated production lines
Applications
The TSM-124-03-TL-DH-A-K-TR is designed for backplane-to-daughter-card interconnects, embedded computing modules, and industrial control systems that require high pin-count SMT connectivity on a standard 2.54 mm grid. Its dual-row layout and polarization key suit test-and-measurement fixtures and FPGA development boards where reliable, repeatable mating is critical.

Frequently Asked Questions
How many positions and what pitch does the TSM-124-03-TL-DH-A-K-TR provide?
The TSM-124-03-TL-DH-A-K-TR offers 48 positions arranged in 2 rows of 24 pins each on a 2.54 mm (0.100 inch) pitch. This standard pitch ensures broad PCB footprint compatibility with existing 0.100-inch grid designs used across industrial, computing, and prototyping applications.
What current and voltage ratings does the TSM-124-03-TL-DH-A-K-TR support?
Each contact in the TSM-124-03-TL-DH-A-K-TR is rated for 3 A continuous current and 250 V AC working voltage. Gold-plated contacts maintain low contact resistance below 20 mΩ over the operating life, making the connector suitable for mixed signal and power distribution on backplane assemblies.
When should a designer choose TSM-124-03-TL-DH-A-K-TR over a 2-row pin header such as the TSM-124-01 series?
The TSM-124-03-TL-DH-A-K-TR is preferred over a basic 2-row header when tape-and-reel (TR) packaging, a polarization key (K), and dual-height (DH) mating clearance are all required simultaneously. The TR suffix enables automated pick-and-place at volumes above 1000 pieces per reel, and the DH profile provides at least 5 mm of board-to-board standoff for cable routing.
