Key Features
- 6-position dual-row SMT terminal strip on 0.100" (2.54 mm) pitch with DH dual-height profile for stacking flexibility in board-to-board designs
- Tape-and-reel (TR) packaging enabling high-volume automated pick-and-place assembly on standard SMT production lines
- Surface-mount termination with keying (K) feature to prevent mismating and ensure correct orientation during PCB assembly
Applications
The TSM-103-04-SM-DH-A-K-TR is designed for compact 6-signal board-to-board interconnect applications in industrial automation, consumer electronics, and communication equipment. Its dual-row 0.100" pitch layout and keying feature ensure reliable, polarity-protected connections between main boards and expansion modules. Tape-and-reel packaging makes this strip compatible with fully automated SMT assembly processes, reducing placement cycle time and improving throughput in high-volume production runs.

Frequently Asked Questions
What does the keying (K) feature on the TSM-103-04-SM-DH-A-K-TR prevent during board assembly and operation?
The keying feature mechanically prevents mismating between the TSM-103-04-SM-DH-A-K-TR and its mating connector by providing an asymmetric polarization on the 6-position, 0.100" pitch dual-row body. This eliminates reverse-insertion errors on assembly lines running at high speed, protecting circuits from the reverse voltage or signal misrouting that could damage components.
How does the DH dual-height profile of the TSM-103-04-SM-DH-A-K-TR support board stacking in compact enclosures?
The DH designation indicates a taller SMT post height that accommodates board-to-board stacking clearances in enclosures where the two PCBs must maintain a defined separation, typically 4 mm to 8 mm, to allow components on both surfaces to coexist. This makes the TSM-103-04-SM-DH-A-K-TR suitable for daughter-card and shield-board designs in industrial controllers and wireless modules.
Which production environments benefit most from the tape-and-reel packaging of the TSM-103-04-SM-DH-A-K-TR?
High-volume SMT production lines that process thousands of PCBs per shift benefit most from the TR packaging, which feeds the 6-position connector directly into pick-and-place machines at rates exceeding 5,000 placements per hour without manual handling. This reduces per-unit placement cost compared to tube or tray packaging, making the TSM-103-04-SM-DH-A-K-TR a cost-effective choice for consumer electronics and industrial gateway products.
