What are the key features of TSM-143-01-LM-DV-P-TR?
- 86-position dual-row layout at 0.100" (2.54 mm) pitch ensures compatibility with standard 2.54 mm grid PCB footprints
- Low-profile mating (LM) design reduces mated height, ideal for height-constrained enclosures and board stack-ups
- Dual-row vertical (DV) orientation provides maximum pin density per board area for wide parallel bus applications
- Tape-and-reel (-TR) packaging supports high-throughput automated SMT pick-and-place assembly
What is TSM-143-01-LM-DV-P-TR used for?
The TSM-143-01-LM-DV-P-TR is suited for backplane, industrial I/O, and embedded computing applications where 86 surface-mount contacts at 2.54 mm pitch are required in a low-mating-profile configuration. Its dual-row vertical format is used in wide parallel bus connections for communication boards, test and measurement equipment, and industrial automation controllers. The low-profile mating design is especially useful in thin product enclosures with strict board height budgets.

Frequently Asked Questions
What does the LM designation in TSM-143-01-LM-DV-P-TR mean for board assembly?
The LM designation stands for Low-profile Mating, meaning the connector is designed to minimize the combined height of the connector pair when fully mated. For an 86-position dual-row terminal strip at 0.100" (2.54 mm) pitch, this low mating profile is critical in height-constrained enclosures where standard or tall mating connectors would exceed the available board-to-board clearance.
How many signal connections does the TSM-143-01-LM-DV-P-TR support and at what pitch?
The TSM-143-01-LM-DV-P-TR supports 86 total signal connections in a dual-row vertical arrangement, with 43 positions per row at 0.100" (2.54 mm) pitch. This standard pitch ensures broad compatibility with common PCB design rules and manufacturing tolerances, making it suitable for industrial, embedded, and communication interface applications.
Can the TSM-143-01-LM-DV-P-TR be used in high-volume automated assembly?
Yes. The -TR suffix indicates tape-and-reel packaging, enabling the TSM-143-01-LM-DV-P-TR to be fed directly into automated SMT pick-and-place equipment. Combined with its surface-mount termination, this allows high-throughput placement and standard reflow soldering at peak temperatures around 260°C in volume PCB production environments.
When should a designer choose TSM-143-01-LM-DV-P-TR over TSM-143-04-F-DV-P-TR?
A designer should choose the TSM-143-01-LM-DV-P-TR over the TSM-143-04-F-DV-P-TR when the application has a strict mated height constraint, as the LM (Low-profile Mating) variant reduces the board-to-board stack height compared to the standard flat (F) termination variant. Both offer 86 positions at 0.100" (2.54 mm) pitch in dual-row surface-mount format, but the LM version trades slightly different footprint geometry for a lower profile after mating.
