What is SMH-104-02-L-S used for?
The Samtec SMH-104-02-L-S is used in board-to-board and wire-to-board interconnect applications in embedded computing, test and measurement instruments, and industrial control PCBs where a standard 0.100 inch pitch socket is required in a horizontal surface-mount orientation. Its gold-plated contacts support reliable signal integrity in low-voltage digital and mixed-signal circuits operating up to several hundred MHz. Engineers also use this socket strip for daughter-card attachment in prototyping systems, development boards, and daughterboard expansion modules where frequent mating and un-mating is required.

Frequently Asked Questions
How many signal positions does the SMH-104-02-L-S provide, and in what pin arrangement?
The SMH-104-02-L-S is a dual-row socket strip with 4 positions total arranged on a 0.100 inch (2.54 mm) pitch. This standard pitch ensures compatibility with a wide range of 0.100 inch pitch headers and pin strips from multiple vendors, making it straightforward to source mating connectors for board-to-board or wire-to-board assemblies without custom tooling.
What contact finish does the SMH-104-02-L-S use, and how does it affect connector longevity?
The SMH-104-02-L-S features gold (10 µin) plating over a nickel (50 µin) underplate on the mating surfaces. Gold plating provides excellent corrosion resistance and low, stable contact resistance even after hundreds of mating cycles. The nickel barrier prevents gold diffusion into the copper base and extends the usable life of the socket in environments with moderate humidity and temperature cycling.
Can the SMH-104-02-L-S be assembled using standard SMT reflow processes, and what are its body dimensions?
Yes, the SMH-104-02-L-S is designed for surface-mount assembly compatible with standard reflow soldering processes. Its body measures approximately 0.42 inch in length and 0.47 inch in depth, fitting within typical SMT keep-out zones. The horizontal orientation means it lies flat on the PCB, enabling low-profile board stacking or edge-mount configurations in height-constrained enclosures.
In which prototyping or development-board scenarios would the SMH-104-02-L-S be preferred over a through-hole socket strip?
In fine-pitch, high-density PCB layouts where through-hole drilling would compromise inner copper layers or reduce routing channels, the SMH-104-02-L-S surface-mount version preserves all 4 inner layers. With a 2-week lead time from Samtec's Tiger Buy program and gold contacts rated for extended mating cycles, it is commonly used in development boards, FPGA breakout modules, and test fixtures where the connector is accessed regularly and PCB space at the 0.100 inch grid is at a premium.
