Key Features
- 38-position dual-row layout at 0.100 inch (2.54 mm) pitch offers high contact density for complex multi-signal board interconnect applications
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly for high-volume SMT production lines with minimal handling waste
- Surface mount termination with dual-height (DH) option provides additional mechanical stability and alignment control during reflow soldering
- Key (K) polarization feature prevents incorrect mating orientation, reducing assembly errors in multi-connector PCB designs
Applications
The TSM-119-02-TM-DH-A-K-TR is designed for high-density board-to-board or wire-to-board interconnect in industrial automation controllers, embedded computing platforms, and test equipment backplanes where 38 signal positions are required in a single connector. The dual-height and keyed options make it particularly suitable for production environments where correct assembly orientation is critical to prevent damage. Its tape-and-reel packaging enables seamless integration into automated SMT lines for consistent, high-volume manufacturing.

Frequently Asked Questions
How many positions does TSM-119-02-TM-DH-A-K-TR have, and what pitch does it use?
The TSM-119-02-TM-DH-A-K-TR has 38 positions arranged in a dual-row format at a standard 0.100 inch (2.54 mm) pitch. This high pin count in a single connector simplifies cabling in industrial controllers, embedded computing boards, and test instrumentation backplanes requiring many simultaneous signal connections.
What does the tape-and-reel (TR) suffix mean for production assembly of TSM-119-02-TM-DH-A-K-TR?
The TR suffix indicates tape-and-reel packaging, meaning parts are supplied on a continuous carrier reel compatible with standard SMT pick-and-place machines. This packaging supports automated high-volume assembly lines without manual handling, reducing placement error rates and allowing production throughput of hundreds of boards per hour.
Why is the key (K) feature important in a 38-position connector like TSM-119-02-TM-DH-A-K-TR?
The key (K) polarization prevents reverse or incorrect mating of the 38-position connector, which is critical in complex PCB assemblies with multiple similar-looking connectors adjacent to each other. Without keying, an assembler could easily insert a 38-pin mating connector in the wrong orientation, potentially damaging ICs or connectors at 3.3 V or 5 V logic supply rails.
In which PCB design scenarios does the dual-height (DH) option on TSM-119-02-TM-DH-A-K-TR provide an advantage over standard height?
The dual-height option increases the connector body clearance above the PCB surface by a few millimeters, allowing components such as bypass capacitors rated in the range of 0.1 µF to 10 µF to be placed in the area beneath the connector body. This is especially useful in dense board designs where the additional vertical space under a 38-position connector would otherwise be wasted.
