Key Features
- 38-position dual-row SMT terminal strip with 0.100" (2.54 mm) pitch for standard-grid signal distribution on PCBs
- Double-height (DH) shroud provides enhanced mechanical protection and positive polarization to prevent mis-mating
- Tape-and-reel (TR) packaging enables high-throughput automated pick-and-place SMT production assembly
- STL tail configuration delivers controlled solder stand-off height for uniform reflow joint quality across all 38 pins
Applications
The TSM-119-02-STL-DH-A-K-TR is used in industrial control systems, embedded computing boards, and I/O expansion modules where a 38-position, 2.54 mm pitch dual-row SMT terminal strip with a double-height shroud provides reliable, polarized board-to-board or board-to-cable signal distribution. The double-height shroud offers additional mechanical keying and improved connector mating guidance, making it suitable for applications subject to vibration or frequent connector mating such as test fixtures and field-replaceable interface modules. Tape-and-reel packaging supports high-volume automated SMT assembly lines in consumer electronics, telecommunications, and industrial manufacturing.

Frequently Asked Questions
What does the DH designator mean on the TSM-119-02-STL-DH-A-K-TR, and how does it improve connector mating reliability?
The DH designator indicates a double-height shroud, which increases the shroud wall height compared to a standard single-height shroud. The taller shroud provides better mechanical guidance during mating, more positive polarization to prevent off-angle insertion, and improved protection of the 38 contacts from accidental damage in applications where connectors are mated and unmated frequently.
How many positions and at what pitch does the TSM-119-02-STL-DH-A-K-TR provide, and what assembly process does it support?
The TSM-119-02-STL-DH-A-K-TR provides 38 positions in a dual-row arrangement at a 0.100" (2.54 mm) pitch. It uses surface-mount termination with an STL tail for controlled solder stand-off, compatible with standard SMT reflow soldering at typical lead-free reflow peak temperatures around 260°C, and arrives in tape-and-reel packaging for automated pick-and-place assembly.
Why would an engineer select the TSM-119-02-STL-DH-A-K-TR over a similar connector without the TR packaging suffix?
The TR (tape-and-reel) suffix means the connectors are pre-loaded in carrier tape on reels, which is required for automated pick-and-place SMT assembly equipment. Without TR packaging, connectors must be placed manually, which is slower, more error-prone, and uneconomical at high production volumes. For production runs of hundreds to thousands of PCBs with this 38-position connector, TR packaging reduces per-board labor cost significantly.
In which electronic system types is the TSM-119-02-STL-DH-A-K-TR most commonly specified?
The TSM-119-02-STL-DH-A-K-TR is most commonly specified in industrial automation HMI panels, embedded single-board computers, PLC I/O expansion cards, test and measurement interface modules, and telecommunications equipment where a 38-position, 2.54 mm pitch dual-row SMT shrouded header with double-height mechanical protection provides dependable and polarized board-to-board or wire-to-board connectivity.
