Key Features
- 10-position dual-row surface mount terminal strip on 0.100 inch (2.54 mm) pitch with gold mating contacts for superior conductivity and corrosion resistance
- Horizontal (SH) low-profile orientation with peg board mounting option enables secure PCB registration during automated SMT assembly and reflow
- Tin over nickel barrier termination contacts provide excellent solderability on lead-free SAC305 solder reflow processes in high-volume production
Applications
The TSM-105-02-LM-SH-A is suited for compact board-to-wire and board-to-board interconnect applications in embedded systems, sensor modules, and consumer electronics where 10 signals must be routed through a 0.5 inch connector footprint. Its horizontal low-profile SMT design reduces overall assembly height, making it ideal for slim enclosures and stacked PCB configurations. The gold mating contacts ensure reliable connectivity in applications requiring repeated mating cycles such as test fixtures and removable module interfaces.

Frequently Asked Questions
What is the pin count, pitch, and physical size of the TSM-105-02-LM-SH-A connector?
The TSM-105-02-LM-SH-A is a 10-position dual-row connector on 0.100 inch (2.54 mm) pitch with a body measuring 0.5 inch long, 0.29 inch deep, and 0.12 inch wide. The dual-row layout provides 5 pins per row, and the horizontal (SH) orientation keeps the mating height low for slim PCB stack-up designs.
How does the gold mating contact on TSM-105-02-LM-SH-A benefit high-cycle applications such as test fixtures?
Gold mating contacts on the TSM-105-02-LM-SH-A maintain low and stable contact resistance typically below 20 mΩ across hundreds to thousands of mating cycles. Unlike tin contacts that develop oxide layers over repeated insertions, gold resists oxidation and fretting corrosion, making this connector suitable for test fixture interfaces and field-replaceable module connectors subject to frequent 10-position mating operations.
What mounting feature does the TSM-105-02-LM-SH-A include to improve SMT assembly accuracy?
The TSM-105-02-LM-SH-A includes a peg (PEG) board mounting option that provides a locating post to register the connector precisely on the PCB during pick-and-place and reflow assembly. This peg prevents connector shift during solder reflow at up to 260°C peak temperature, reducing placement defects in high-volume SMT manufacturing of compact 10-pin board connectors.
When would you select TSM-105-02-LM-SH-A over a through-hole 0.100 inch header for the same 10-pin application?
Choose the TSM-105-02-LM-SH-A surface mount variant when your PCB design is fully SMT-based without through-hole drilling, or when board thickness is limited below 1.6 mm where through-hole plating becomes unreliable. The SMT version saves 0.29 inch depth compared to a vertical through-hole header, enabling tighter board-to-board spacing in stacked 10-pin module configurations.
