Key Features
- 20-position dual-row layout on a 2.54 mm pitch provides a versatile signal interface in a compact SMT footprint
- Through-mount (TM) tail style offers enhanced PCB anchoring compared to standard surface-mount termination
- Dual-height (DH) body accommodates mating connectors with required vertical clearance for stacked-board assemblies
- Tape-and-reel (TR) packaging enables uninterrupted automated pick-and-place production for high-volume SMT lines
Applications
The TSM-110-02-TM-DH-A-K-TR is suited for board-to-board signal interconnects in industrial automation controllers, embedded computing daughtercards, and test-and-measurement equipment requiring a reliable 20-position, 2.54 mm pitch surface mount strip. Its through-mount tails provide additional mechanical retention under vibration, while the dual-height body supports PCB stacking configurations common in modular instrument designs. Tape-and-reel packaging ensures compatibility with automated SMT lines in high-volume electronics manufacturing.

Frequently Asked Questions
What is the pin count and pitch of TSM-110-02-TM-DH-A-K-TR?
The TSM-110-02-TM-DH-A-K-TR provides 20 total positions arranged in 2 rows of 10 contacts each on a 2.54 mm (0.100 inch) pitch. This standard spacing is compatible with the broad SAMTEC TSM mating connector ecosystem and widely used PCB grid layouts in industrial and embedded computing applications.
How does the through-mount tail style of TSM-110-02-TM-DH-A-K-TR compare to standard friction-mount tails for mechanical reliability?
Through-mount (TM) tails pass through PCB vias before soldering, providing mechanical anchoring that resists pull-out forces exceeding 10 N per tail compared to surface-only pads. This makes the TSM-110-02-TM-DH-A-K-TR preferable in applications subject to connector mating forces, vibration, or repeated cable attachment in industrial or ruggedized environments.
Which stacking scenarios benefit from the dual-height body of TSM-110-02-TM-DH-A-K-TR?
The dual-height (DH) body provides additional clearance between mated PCBs, accommodating components that extend above the lower board surface by up to 8.51 mm. This suits modular backplane systems, embedded compute stacks, and instrumentation designs where the mated board pair must clear capacitors, inductors, or IC packages placed between the two PCB planes.
Can TSM-110-02-TM-DH-A-K-TR be used as a lower-position alternative to TSM-125-03-FM-DH-A-K-TR in space-constrained boards?
Yes. The TSM-110-02-TM-DH-A-K-TR offers 20 positions versus the 50-position TSM-125-03-FM-DH-A-K-TR, reducing the connector body length by approximately 60 mm on a 2.54 mm pitch, while maintaining dual-height body compatibility. Designers needing fewer than 25 signal pairs can replace the 50-position version to save board area without changing the mating connector family.
