What are the key features of TSM-129-02-L-SH-A?
- 29 positions dual-row configuration providing 58 contacts at 0.100 inch pitch for high-density board connectivity
- Gold (10 µin) over nickel mating finish ensuring low contact resistance and corrosion resistance over thousands of mating cycles
- Surface-mount horizontal (L) orientation with PEG board mounting option for stable solder reflow attachment
What is TSM-129-02-L-SH-A used for?
The TSM-129-02-L-SH-A is used in modular embedded computing platforms where daughter cards or mezzanine modules connect to a baseboard at 0.100 inch pitch. Its dual-row 58-contact layout provides sufficient signal and power lines for small form-factor SBCs, FPGA development modules, and test fixtures. The horizontal SMT orientation keeps the connector profile low, making it suitable for space-constrained enclosures with height limits under 10 mm.

Frequently Asked Questions
How many usable contacts does the TSM-129-02-L-SH-A provide, and what pitch spacing should the mating connector match?
The TSM-129-02-L-SH-A has 29 positions in a dual-row arrangement, providing 58 contacts total at a 0.100 inch (2.54 mm) pitch. Any standard 0.100 inch dual-row mating connector, such as Samtec's TSW or BCS series, can be used as the receptacle, ensuring compatibility across a wide range of off-the-shelf connectors and cable assemblies.
What contact finish does the TSM-129-02-L-SH-A use, and how many mating cycles can it reliably support?
The mating contacts are finished with 10 µin of gold over a nickel barrier, and the termination side uses tin over nickel. Gold-over-nickel contact finishes typically support 500 to 1000 mating cycles while maintaining contact resistance below 20 mΩ, making this connector suitable for test fixtures and removable module applications that require repeated insertion.
In which embedded computing or prototyping applications is the TSM-129-02-L-SH-A commonly used?
This connector is widely used in FPGA mezzanine card designs, Raspberry Pi-compatible HAT connectors, and custom SBC daughter-card interfaces where 58 pins at 2.54 mm pitch provide adequate I/O expansion. The 2.9 inch body length and SMT horizontal mounting also make it a practical choice for backplane prototyping fixtures that need secure mechanical retention via the PEG option.
How does the TSM-129-02-L-SH-A surface-mount design differ from a through-hole equivalent for production assembly?
The surface-mount TSM series eliminates through-hole drilling in the PCB, reducing fabrication cost by as much as 30% on boards with 4 or more layers. Reflow soldering at 260 °C peak temperature attaches all 58 contacts simultaneously, compared with selective or wave soldering required for through-hole pins, speeding up automated assembly on standard SMT lines.
