What are the key features of TSM-129-01-SM-DH-A-K-TR?

  • 58-position single-row layout at 2.54 mm (0.100 inch) pitch covering approximately 147 mm PCB edge
  • Dual-height (DH) contact design compatible with multiple mating connector stack heights
  • Keyed (K) alignment prevents mis-mating in field-installed industrial and backplane applications
  • Tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly at high production volumes
  • SM contact style provides strong solder joint integrity for single-row surface mount board edge connections

What is TSM-129-01-SM-DH-A-K-TR used for?

The TSM-129-01-SM-DH-A-K-TR is used in long edge connector interfaces, industrial backplane expansions, and embedded computing carrier boards where a 58-position single-row 2.54 mm pitch terminal strip provides an extensive signal bus in a linear footprint. Its keyed alignment and dual-height contacts make it well-suited for modular industrial controllers, VME or CompactPCI expansion, and custom bus architectures requiring polarized 58-pin connectivity. The tape-and-reel format ensures high-yield automated SMT assembly in volume production.

Frequently Asked Questions

What is the total length of the PCB footprint for the TSM-129-01-SM-DH-A-K-TR given its 58-position count and pitch?

With 58 positions at 2.54 mm (0.100 inch) pitch, the TSM-129-01-SM-DH-A-K-TR spans approximately 147 mm in total connector length. This makes it suitable for long edge connector bus interfaces in backplane systems, industrial I/O boards, and expansion card designs that need a single-row connector covering a full board edge.

How does the keyed (K) alignment feature protect the TSM-129-01-SM-DH-A-K-TR from incorrect mating in the field?

The keyed (K) designation means a physical polarization feature is molded into the connector housing, preventing the 58-pin mating connector from being inserted in the wrong orientation. This is essential in industrial and backplane systems where reversed connections across 58 contacts could damage logic signals at 3.3 V or 5 V or create shorts on power rails.

What SMT assembly profile is compatible with the TSM-129-01-SM-DH-A-K-TR, and does it support lead-free soldering?

The TSM-129-01-SM-DH-A-K-TR surface mount termination is compatible with lead-free SMT reflow processes, supporting peak soldering temperatures up to 260°C per IPC J-STD-020. The tape-and-reel packaging also enables automated placement on standard SMT lines, reducing assembly time for high-volume 58-pin connector applications in industrial electronics.

When would a 58-position single-row strip like the TSM-129-01-SM-DH-A-K-TR be selected over a dual-row alternative?

A 58-position single-row strip is selected when the PCB edge connector design requires all contacts to be accessible from one side, such as in card-edge bus interfaces and slot connector systems. Compared to a dual-row 29-position connector at the same pitch, the single-row layout keeps the connector body breadth under 5 mm while covering a 147 mm signal bus, which suits narrow card-edge PCB designs in industrial and embedded computing applications.
