What are the key features of TSM-114-03-TM-DH-P-TR?
- 28-position dual-row SMT terminal strip with 0.100" (2.54 mm) standard pitch for broad compatibility with existing PCB grid layouts
- Double-height (DH) shroud provides mechanical polarization and contact protection to prevent mis-mating across all 28 pins
- TM tail configuration enables surface-mount reflow soldering without through-hole drilling, simplifying PCB fabrication
- Tape-and-reel (TR) packaging supports fully automated pick-and-place SMT assembly for high-volume production
What is TSM-114-03-TM-DH-P-TR used for?
The TSM-114-03-TM-DH-P-TR is used in embedded computing systems, industrial I/O modules, and consumer electronics where a 28-position, 2.54 mm pitch dual-row SMT shrouded terminal strip provides polarized, mechanically protected board-to-board or cable-to-board signal connections. Its double-height shroud and standard 2.54 mm pitch make it compatible with a wide selection of mating connectors, simplifying system design for I/O expansion cards, sensor interface boards, and relay control modules. Tape-and-reel packaging enables cost-effective high-volume automated assembly in manufacturing environments requiring consistent placement accuracy.

Frequently Asked Questions
What is the pin count and pitch of the TSM-114-03-TM-DH-P-TR, and how does the dual-row layout benefit board layout?
The TSM-114-03-TM-DH-P-TR has 28 positions in a dual-row configuration at 0.100" (2.54 mm) pitch. The dual-row layout places 14 pins per row, halving the connector's board length compared to a single-row 28-pin strip at the same pitch, which saves PCB real estate while maintaining the standard 2.54 mm grid spacing compatible with most mating connectors.
How does the double-height shroud on the TSM-114-03-TM-DH-P-TR protect the connector in field-service or frequent mating scenarios?
The double-height (DH) shroud extends the plastic housing walls taller than a standard shroud, fully enclosing the 28 signal pins and providing a guided entry path for the mating connector. This prevents off-center insertions, protects pins from mechanical damage during handling, and enforces polarization so the mating connector can only be inserted in the correct orientation, reducing field-service errors.
Can the TSM-114-03-TM-DH-P-TR be used with automated SMT assembly equipment, and what packaging does it come in?
Yes, the TR suffix indicates tape-and-reel packaging, which is fully compatible with standard automated pick-and-place SMT assembly equipment. Each connector is seated in a carrier tape wound on a reel, allowing assembly machines to place the 28-pin connector accurately on the PCB pad pattern before reflow soldering, making it suitable for high-volume production runs with consistent placement quality.
For which end applications is the TSM-114-03-TM-DH-P-TR preferred over a wire-to-board screw terminal?
The TSM-114-03-TM-DH-P-TR is preferred over screw terminals in high-density PCB-to-PCB or PCB-to-cable applications where space is limited, assembly speed matters, and polarization is required. With 28 positions at 2.54 mm pitch in a compact dual-row SMT package, it suits embedded controller boards, sensor fusion modules, I/O expansion cards, and industrial communication interfaces where a screw terminal's large footprint and manual wiring are impractical.
