Key Features
- 24 positions (2x12) on 2.54 mm / .100" pitch for reliable dual-row board-to-board signal connections
- Solderable tail (STL) contacts provide mechanical retention through through-hole soldering for vibration-resistant applications
- Tape-and-reel (TR) packaging fully compatible with automated SMT pick-and-place assembly lines
- Tin-plated contacts ensure reliable solderability in standard lead-free reflow processes
Applications
The TSM-112-02-STL-DH-A-K-TR is suited for embedded microcontroller boards, sensor interface modules, and industrial I/O expansion headers where 24 dual-row signals on 2.54 mm pitch are needed. Its solderable tail contacts make it a mechanically robust choice for applications subject to vibration or repeated connector mating, such as field instruments and panel-mount PCBs. Tape-and-reel delivery enables efficient integration into automated SMT production lines.

Frequently Asked Questions
What pin layout and pitch does the TSM-112-02-STL-DH-A-K-TR provide?
The TSM-112-02-STL-DH-A-K-TR provides 24 positions in a dual-row (2x12) arrangement on a 2.54 mm (.100") pitch. This configuration is a standard choice for microcontroller expansion headers and industrial sensor interface boards needing 24 bidirectional signal pins in a compact dual-row format.
How does the STL solderable tail improve mechanical performance compared to standard SMT-only connectors?
The STL (solderable tail) design adds through-hole pins below the SMT pads, allowing the connector to be soldered to both the surface lands and through the board. For a 24-pin, 2.54 mm pitch terminal strip, this dual-retention method significantly increases pull-out strength and vibration resistance compared to surface-mount-only attachment, making it suitable for field instrument and panel-mount applications.
When would a designer choose the 24-pin TSM-112-02-STL-DH-A-K-TR over a 36- or 44-pin variant?
A 24-pin (2x12) terminal strip is appropriate when the application requires fewer than 30 signals and PCB space or routing complexity would be wasted with a larger 36- or 44-pin connector. It is commonly selected for compact sensor hubs, 24-bit data bus expansions, or sub-modules in modular embedded systems where a 2.54 mm pitch dual-row interface suffices.
Is the TSM-112-02-STL-DH-A-K-TR suitable for lead-free reflow soldering processes?
Yes, the TSM-112-02-STL-DH-A-K-TR uses tin-plated contacts and is compatible with standard lead-free reflow soldering at typical peak temperatures of 260°C. Its tape-and-reel (TR) format and surface mount body allow it to be placed and reflowed in standard SMT ovens alongside other components on the 2.54 mm pitch PCB assembly.
