What are the key features of TSM-123-03-H-DH-A-K-TR?
- 46-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch with high-shroud (H) and dual-height (DH) keying to prevent mis-insertion
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place at high throughput for volume production runs
- Polarized dual-height shroud design provides positive mechanical keying, ensuring correct mating orientation on every insertion
What is TSM-123-03-H-DH-A-K-TR used for?
The TSM-123-03-H-DH-A-K-TR is designed for modular board stacking and PCB-to-module interconnect applications in industrial automation, embedded systems, and test and measurement equipment that require a reliable 46-pin polarized interface at 0.100" pitch. The high-shroud and dual-height design prevents incorrect insertion in field-replaceable module assemblies, reducing service errors. Tape-and-reel packaging makes this connector well-suited for high-volume SMT production lines using automated placement equipment.

Frequently Asked Questions
What does the high-shroud dual-height (H-DH) designation mean for the TSM-123-03-H-DH-A-K-TR?
The H-DH designation means the connector features a high-profile shroud with dual-height construction that physically keys the mating pair to prevent incorrect connector orientation. This ensures the 46-position, 0.100" pitch interface can only mate in the correct direction, reducing assembly errors and protecting all 46 signal pins from damage during insertion in automated or field-service environments.
Why would an engineer select TSM-123-03-H-DH-A-K-TR over a non-shrouded 46-pin header for a modular industrial controller?
In field-replaceable module applications such as industrial PLC expansion cards or test fixture boards, a non-shrouded header carries a risk of off-by-one mis-insertion that can damage circuits or short 3.3 V or 5 V supply rails. The TSM-123-03-H-DH-A-K-TR eliminates this by enforcing single-orientation mating through the dual-height shroud, protecting all 46 positions and potentially saving costly rework cycles in systems with hundreds of installed units.
How many mating positions and what pitch does the TSM-123-03-H-DH-A-K-TR support, and how does tape-and-reel help procurement?
The TSM-123-03-H-DH-A-K-TR provides 46 positions in 2 rows at 0.100" (2.54 mm) pitch across a PCB footprint of approximately 58 mm in length. The TR (tape-and-reel) packaging format is compatible with standard SMT pick-and-place machines, allowing placement of 1000 or more parts per reel with consistent positional accuracy, which reduces per-unit assembly cost versus tube or tray packaging for production volumes above a few hundred pieces.
