Key Features
- 29-position dual-row configuration on 0.100-inch pitch delivers high-density signal routing in a surface-mount form factor
- Stainless steel (SS) contacts provide superior corrosion resistance and mechanical durability over gold-plated copper alternatives in humid environments
- Single-row horizontal mating orientation (SH) reduces connector stack height and keeps mated assemblies profile low for compact board designs
Applications
The TSM-129-02-SS-SH-A is ideal for industrial backplane assemblies, modular test fixtures, and embedded computing boards requiring 29 signal connections in a low-profile, surface-mount format. Its horizontal mating orientation suits edge-card and daughter-board installations where vertical clearance is limited, and the stainless-steel contacts ensure reliable mating integrity across extended field service cycles.

Frequently Asked Questions
How many positions does the TSM-129-02-SS-SH-A offer and what is its contact pitch?
The TSM-129-02-SS-SH-A provides 29 positions arranged in a dual-row pattern on a 0.100-inch (2.54 mm) pitch. This layout routes up to 29 discrete signals between a PCB and a mating cable or board assembly using a standard 0.100-inch compatible crimp or socket connector.
What advantage do stainless steel contacts provide in the TSM-129-02-SS-SH-A compared to standard copper contacts?
Stainless steel contacts in the TSM-129-02-SS-SH-A deliver higher yield strength, resisting permanent deformation after repeated mating cycles that can exceed 50 insertions. The corrosion resistance of stainless steel also maintains low contact resistance below 30 milliohms in humid or salt-spray environments where copper-alloy contacts would oxidize and degrade signal integrity.
Why choose a surface-mount terminal strip like the TSM-129-02-SS-SH-A over a through-hole variant for a compact PCB?
SMT mounting of the TSM-129-02-SS-SH-A eliminates 29 drilled holes from the PCB, freeing inner-layer routing channels and reducing PCB fabrication cost. The surface-mount pads can be reflowed with standard solder paste in an SMT line without a separate wave-solder step, simplifying production of compact 4-layer boards with dense 0.100-inch connector fields.
In what scenarios does the single-row horizontal mating style of the TSM-129-02-SS-SH-A outperform vertical mating connectors?
When overall assembly height is constrained to under 10 mm, horizontal mating of the TSM-129-02-SS-SH-A keeps the mated cable or daughter board lying flat against the baseboard, avoiding stack-height conflicts with enclosure lids. This is particularly valuable in industrial panel-mount electronics where depth and not width is the limiting enclosure dimension.
