Key Features
- 29-position dual-row layout on 0.100" (2.54 mm) pitch providing industry-standard compatibility with mating headers
- Surface mount horizontal orientation enabling low-profile board-edge or midboard placement
- Shielded (SH) variant construction reduces EMI coupling in noise-sensitive signal distribution assemblies
Applications
The TSM-129-03-TM-SH-A is used in PCB designs requiring a mid-density, dual-row signal interface at the standard 2.54 mm pitch, such as backplane interconnects, development boards, and industrial control panels. Its shielded design makes it appropriate for applications where electromagnetic interference must be minimized, including communication equipment and test-and-measurement instrumentation. The surface mount horizontal footprint fits compact chassis designs where vertical clearance is constrained.

Frequently Asked Questions
What pitch and position count does the TSM-129-03-TM-SH-A provide?
The TSM-129-03-TM-SH-A is a 29-position dual-row terminal strip built on the standard 0.100" (2.54 mm) pitch. The dual-row arrangement provides 58 total contacts when fully populated, enabling high pin-count interfaces on a compact PCB footprint using widely available 2.54 mm mating headers.
How does the shielded construction of the TSM-129-03-TM-SH-A benefit noise-sensitive designs?
The SH designation indicates an integrated shield around the connector body, which reduces electromagnetic interference coupling into adjacent signal lines. For designs carrying differential pairs or high-speed signals at frequencies above 50 MHz, this shielding can lower crosstalk by several decibels compared to unshielded terminal strips, improving signal integrity in communication and instrumentation applications.
Can the TSM-129-03-TM-SH-A be used as a direct mechanical replacement for through-hole dual-row headers in a redesign?
No direct mechanical swap is possible because the TSM-129-03-TM-SH-A uses surface mount solder tails rather than through-hole pins. A PCB redesign is required to replace through-hole footprints with the SMT pads for this connector. However, the 2.54 mm pitch ensures the mating plug or cable assembly remains compatible, allowing the board-level interface to stay unchanged while gaining the assembly benefits of reflow soldering.
