What are the key features of TSM-135-02-SM-DH-A-K-TR?
- 70 positions in dual-row layout on 0.100" (2.54 mm) pitch for high pin-count SMT interconnect
- Dual-height (DH) construction enabling compatibility with surface-mount and through-hole mating connectors
- SMT termination style for fully automated reflow solder assembly without hand soldering
- Tape-and-reel (TR) packaging optimized for high-volume pick-and-place manufacturing
- RoHS compliant with gold-plated contacts for extended mating reliability
What is TSM-135-02-SM-DH-A-K-TR used for?
The TSM-135-02-SM-DH-A-K-TR is used in industrial automation, communications infrastructure, and test and measurement PCBs where 70-position dual-row signal routing is required in a compact SMT format. Its dual-height profile gives designers the choice of mating with both standard and tall header strips, supporting modular board stacking architectures. Tape-and-reel delivery enables efficient integration into high-throughput SMT production lines.

Frequently Asked Questions
How many signal positions does the TSM-135-02-SM-DH-A-K-TR provide, and how are they arranged physically?
The TSM-135-02-SM-DH-A-K-TR provides 70 positions arranged in a dual-row configuration on 0.100 inch (2.54 mm) pitch, allowing up to 70 independent signal connections within a single SMT connector body on the PCB.
What does the SM designation indicate about how TSM-135-02-SM-DH-A-K-TR is mounted to the PCB?
The SM designation confirms surface-mount termination, meaning all 70 contact tails are designed to be reflow-soldered to SMT pads rather than inserted through holes. This is compatible with standard lead-free reflow profiles up to 260°C and eliminates through-hole drilling costs.
Can TSM-135-02-SM-DH-A-K-TR be used with both standard-height and tall mating connectors in board stacking applications?
Yes, the dual-height (DH) feature allows TSM-135-02-SM-DH-A-K-TR to mate with connectors of varying stack heights, providing designers flexibility for PCB-to-PCB configurations where board-to-board spacing varies between 8 mm and taller stack heights in modular system designs.
When qualifying TSM-135-02-SM-DH-A-K-TR for an industrial design, does it meet RoHS and lead-free requirements?
Yes, TSM-135-02-SM-DH-A-K-TR is RoHS compliant with a gold-plated contact finish and tin-based SMT termination, supporting environmentally compliant manufacturing. Its 70-position body is rated for standard industrial temperature ranges, making it suitable for -40°C to 85°C operating environments.
