Key Features
- 54-position dual-row SMT terminal strip with 2.54 mm (0.100 inch) pitch for high-density board-to-board signal connections
- Low-profile (LM) mounting style minimizing component height above the PCB surface for space-constrained stacked board assemblies
- Tape-and-reel (TR) packaging enabling fully automated pick-and-place assembly in high-volume SMT production lines
Applications
The TSM-127-01-LM-DH-A-K-TR is suited for modular embedded systems, networking cards, and industrial I/O boards requiring 54 surface mount contact positions in a compact 2.54 mm pitch dual-row format. Its low-profile SMT footprint and tape-and-reel packaging support automated assembly in high-volume production of server expansion modules, data acquisition systems, and field programmable gate array daughter cards.

Frequently Asked Questions
How does the LM mounting style of TSM-127-01-LM-DH-A-K-TR differ from a standard vertical SMT terminal strip?
The LM designation specifies a low-profile mounting style that reduces the connector's height above the PCB surface compared to standard vertical SMT options. This is important for stacked board designs where total assembly height must remain below a specific limit, such as in 1U rack modules or multi-board assemblies with less than 5 mm vertical clearance.
What pin count and pitch does the TSM-127-01-LM-DH-A-K-TR provide for board interconnect designs?
The TSM-127-01-LM-DH-A-K-TR offers 54 positions arranged in a dual-row layout with 2.54 mm (0.100 inch) pitch, providing 27 contacts per row. This configuration supports high-density multi-signal routing between boards in networking equipment, embedded computers, and industrial data acquisition modules.
For procurement planning, is the TSM-127-01-LM-DH-A-K-TR available in reel quantities suitable for production runs?
Yes, the -TR suffix confirms tape-and-reel packaging, with typical reels containing 500 to 1000 connectors per reel depending on connector size. This format integrates directly into SMT pick-and-place workflows, reducing per-unit handling time and supporting continuous production runs of hundreds or thousands of PCB assemblies.
