What are the key features of TSM-103-04-LM-DH-A-K-TR?
- 6-position SMT terminal strip at 0.100" (2.54 mm) pitch in a dual-height right-angle configuration that minimizes board height while allowing side-access cable mating
- Low-mount (-LM) profile reduces PCB height clearance requirements, enabling installation in thin enclosures or stacked board assemblies
- Tape-and-reel (-TR) and polarization (-K) options streamline automated assembly and prevent mis-mating of the 6-contact connector in production environments
What is TSM-103-04-LM-DH-A-K-TR used for?
The TSM-103-04-LM-DH-A-K-TR is suitable for embedded control boards, compact sensor modules, and wearable electronics where a 6-position right-angle SMT header at 2.54 mm pitch with minimal height is required. Its dual-height profile and right-angle entry make it practical for USB, power-rail, or interface headers on boards installed inside shallow housings or stacked assemblies with tight vertical clearances.

Frequently Asked Questions
What does the dual-height right-angle configuration of the TSM-103-04-LM-DH-A-K-TR enable in compact board designs?
The dual-height (DH) right-angle (A) design allows the 6-position connector to accept a mating cable entering parallel to the PCB surface while also accommodating two different mating heights, typically for standard and low-profile cable plug bodies at 0.100" (2.54 mm) pitch. This flexibility reduces the need for two separate connector part numbers when both standard and low-profile cable assemblies must be supported in the same product family.
How does the low-mount (-LM) suffix in TSM-103-04-LM-DH-A-K-TR benefit board stacking or enclosure-constrained designs?
The low-mount variant reduces the above-board height of the 6-position connector body compared to a standard TSM header, allowing stacked PCB assemblies to maintain a minimum 10 mm or less inter-board gap. This is critical in PCMCIA, mini-PCIe, and embedded compute form factors where total stack height budgets of 15 mm or less must accommodate both the connector and the mating cable relief.
What role does the -K polarization option play in preventing assembly errors on the TSM-103-04-LM-DH-A-K-TR?
The -K suffix adds a physical polarization post or keying feature to the 6-position housing, ensuring the mating connector can only insert in one orientation. Without this feature, a 6-contact header at 0.100" (2.54 mm) pitch could accept a reversed plug, incorrectly mapping power and ground pins across all 6 positions and potentially damaging downstream circuitry. The -K option eliminates that risk in both prototype and production environments.
How does the TSM-103-04-LM-DH-A-K-TR compare to a through-hole equivalent for a 6-pin 2.54 mm pitch right-angle header?
The SMT TSM-103-04-LM-DH-A-K-TR eliminates through-hole drilling and wave soldering steps, reducing PCB fabrication cost and enabling single-side reflow processing. Through-hole right-angle headers of the same 6-pin, 0.100" (2.54 mm) pitch typically have better mechanical pull-out strength (above 5 N per contact) but require a thicker PCB to maintain barrel integrity, making the SMT variant preferable in thin multilayer boards below 1.2 mm where drill spacing would compromise layer clearance.
