Key Features
- 34-position surface mount terminal strip at 2.54 mm (0.100") pitch for moderate-density board interconnect
- Low-profile (LM) and dual-height (DH) construction for flexible mechanical clearance in stacked designs
- P-suffix polarization feature preventing incorrect mating orientation
- Tape and reel (TR) packaging for automated high-volume pick-and-place SMT assembly
- Robust SMT footprint compatible with lead-free reflow soldering up to 260°C
Applications
The TSM-117-03-LM-DH-P-TR is suited for signal distribution and board-to-board interconnect in industrial control panels, embedded computing modules, and test instrumentation requiring a compact 34-position SMT strip. Its polarized, dual-height design ensures correct connector orientation and mechanical clearance in dense PCB assemblies where mismatings must be prevented during manufacturing or field servicing.

Frequently Asked Questions
What does the LM-DH designation mean for the TSM-117-03-LM-DH-P-TR connector profile?
LM denotes a low-profile housing reducing overall height versus standard TSM variants, while DH indicates dual-height construction that provides two distinct mating levels within the 34-position, 2.54 mm pitch body. This combination allows component clearance on adjacent PCB layers in densely stacked board assemblies.
How does the P (polarization) feature in TSM-117-03-LM-DH-P-TR prevent assembly errors on 34-position connectors?
The P suffix introduces a mechanical keying or polarization feature that permits mating with only the correct counterpart connector in the proper orientation. This prevents incorrect 180-degree insertion across all 34 positions, reducing rework costs and protecting sensitive signal lines during high-volume SMT assembly operations.
When should a designer choose TSM-117-03-LM-DH-P-TR over a standard 34-pin through-hole connector for an industrial PCB?
The TSM-117-03-LM-DH-P-TR is preferred when the PCB design requires SMT reflow assembly rather than wave solder through-hole placement, and when board height is constrained to the low-profile LM form factor. At 2.54 mm pitch across 34 positions, it also simplifies routing compared to fine-pitch 1.27 mm alternatives in moderate-speed signal applications.
