Applications
The TSM-129-03-L-SH-A is suited for board-level signal and power distribution in industrial control panels, test fixtures, and development evaluation boards where 2.54 mm pitch connectors are standard. Its 58-contact dual-row configuration supports dense I/O expansion headers for microcontroller development boards, FPGA carrier cards, and backplane interconnects. The surface-mount horizontal form factor is also commonly used in rack-mounted instruments and data acquisition modules where low-profile edge connectivity is required.

Frequently Asked Questions
How many total contacts does the TSM-129-03-L-SH-A provide, and what pitch spacing is used?
The TSM-129-03-L-SH-A is a 29-position dual-row connector, providing 58 total contacts arranged on a 2.54 mm (0.100") pitch grid. This standard pitch ensures compatibility with a wide range of mating headers, ribbon cable connectors, and prototyping sockets used in electronics development and production.
What is the advantage of the horizontal (L) orientation on the TSM-129-03-L-SH-A for board design?
The horizontal right-angle orientation of the TSM-129-03-L-SH-A positions the mating interface parallel to the PCB surface, allowing cables or mating connectors to exit along the board edge. This reduces vertical height requirements in enclosures with tight clearance and enables convenient front-panel or edge-access wiring in instruments, PLCs, and rack equipment using the standard 2.54 mm pitch.
Is the TSM-129-03-L-SH-A compatible with standard 2.54 mm pitch mating connectors and ribbon cables?
Yes, the TSM-129-03-L-SH-A follows the industry-standard 2.54 mm (0.100") pitch, making it compatible with common dual-row mating connectors, IDC ribbon cable assemblies, and headers from multiple manufacturers. The 29-position dual-row layout with 58 contacts mates with standard 58-pin IDC sockets and similar products used across the electronics industry for low-frequency signal and power interconnects.
Can the TSM-129-03-L-SH-A be used in high-volume automated SMT assembly processes?
Yes, the TSM-129-03-L-SH-A is a surface-mount component compatible with automated pick-and-place equipment and standard SMT reflow solder processes. The shrouded SMT body provides mechanical alignment and retention, and SAMTEC supplies this series in tape-and-reel or tray packaging to support high-volume production lines requiring 58-contact 2.54 mm pitch connectors.
