What are the key features of TSM-129-03-LM-DH-A-K-TR?

  • 58-position dual-row layout at 0.100" (2.54 mm) pitch balances signal density with standard PCB design rules
  • Low-profile mounting (-LM) reduces connector height for space-constrained PCB assemblies and slim enclosures
  • Tape-and-reel (-TR) packaging supports high-volume automated pick-and-place and reflow soldering processes

What is TSM-129-03-LM-DH-A-K-TR used for?

The TSM-129-03-LM-DH-A-K-TR is designed for board-to-board and wire-to-board connections in industrial controllers, embedded computing systems, and communication equipment requiring 58-pin dual-row connectivity at 2.54 mm pitch. Its low-profile mounting height makes it particularly useful in stacked-board assemblies and slim-chassis applications where vertical clearance is constrained. The surface mount design with tape-and-reel packaging enables efficient automated manufacturing at scale.

Frequently Asked Questions

What is the significance of the low-profile mounting designation in the TSM-129-03-LM-DH-A-K-TR?

The -LM suffix indicates a low-profile mounting configuration that reduces the connector's above-board height, enabling tighter board-to-board stacking distances below 8 mm for the 58-position dual-row terminal strip at 2.54 mm pitch.

How does the TSM-129-03-LM-DH-A-K-TR fit within the TSM series when comparing pin counts?

The TSM-129 variant provides 58 positions, placing it between the TSM-128 (56 pins) and TSM-130 (60 pins) in the series. All share 0.100" (2.54 mm) pitch dual-row geometry, so designers can step up or down in 2-pin increments to match signal count requirements.

Which production environments benefit from the tape-and-reel packaging of the TSM-129-03-LM-DH-A-K-TR?

High-volume production lines using automated surface mount technology (SMT) equipment benefit most, as the -TR tape-and-reel format is directly compatible with standard pick-and-place feeders for efficient placement of the 58-pin connector followed by reflow soldering at up to 260°C.
