What are the key features of TSM-128-01-LM-DH-P-TR?

  • 56-position dual-row layout at 0.100" (2.54 mm) pitch providing dense signal routing
  • Low-profile LM mating height minimizing stack height in space-constrained assemblies
  • Surface mount termination enabling standard SMT reflow assembly processes
  • Tape-and-reel (TR) packaging optimized for high-volume automated pick-and-place production
  • Dual-row DH housing for secure mechanical retention and consistent mating alignment

What is TSM-128-01-LM-DH-P-TR used for?

The TSM-128-01-LM-DH-P-TR suits backplane interconnects, computer-on-module (COM) expansion headers, and industrial I/O boards where 56 signals must be routed between PCBs in a compact surface mount footprint. Its tape-and-reel packaging and low-profile design are particularly valued in high-volume embedded computing and telecommunications equipment where assembly line efficiency and board height budgets are tightly controlled.

Frequently Asked Questions

How many contact positions does the TSM-128-01-LM-DH-P-TR provide, and in what arrangement?

The TSM-128-01-LM-DH-P-TR provides 56 positions in a dual-row arrangement at 0.100 inch (2.54 mm) pitch, yielding 28 contacts per row. This configuration is well suited for parallel bus interfaces, high-density GPIO expansion headers, and board-to-board interconnects in embedded computing platforms where a large number of signals must cross between PCBs in a minimal footprint.

What procurement benefit does the TR tape-and-reel packaging of TSM-128-01-LM-DH-P-TR offer for production builds?

The TR (tape-and-reel) packaging of TSM-128-01-LM-DH-P-TR is compatible with automated SMT pick-and-place equipment, reducing per-unit handling cost and placement errors compared to individually packaged connectors. High-volume buyers can order quantities on standard reels, enabling continuous production runs without manual loading interruptions and supporting lean manufacturing targets for electronics assembly lines.

When would a designer choose TSM-128-01-LM-DH-P-TR over a higher-position SAMTEC TSM connector such as TSM-150?

The TSM-128-01-LM-DH-P-TR with 56 positions is chosen when the interface bus requires exactly 56 signals, avoiding unused pins that add cost and PCB area. A larger TSM-150 (100-position) would increase footprint and cost unnecessarily. The 56-position count also maps neatly to 7-bit address buses with data lines, making it common in memory expansion headers and DSP daughtercard designs operating at 0.100 inch pitch.
