Key Features
- 0.100 inch (2.54 mm) pitch dual-row horizontal SMT socket with 26 total contacts for compact board-to-board signal interconnects
- Horizontal surface-mount orientation reduces PCB stack height by eliminating the vertical clearance required by through-hole pin headers
- Tape-and-reel (TR) packaging is optimized for automated SMT assembly, reducing handling time in high-volume production environments
- Standard 2.54 mm grid ensures drop-in mating compatibility with common dual-row 0.100 inch pin headers and IDC ribbon-cable connectors
Applications
The SMH-113-02-F-S-TR provides a 26-contact, 0.100 inch pitch horizontal socket for board-to-board and module-to-baseboard interconnections where a low overall assembly height is required. Embedded systems, industrial sensor modules, and development boards use this connector to route GPIO, SPI, I2C, and power signals between a main board and a small daughter card without requiring vertical clearance above the socket. Its tape-and-reel form factor makes it well suited for automated SMT production lines manufacturing compact IoT gateways, motor controllers, and data-acquisition boards.

Frequently Asked Questions
How many total contacts does SMH-113-02-F-S-TR offer and on what grid spacing?
The SMH-113-02-F-S-TR provides 26 total contacts arranged in 2 rows of 13 positions each, on a standard 0.100 inch (2.54 mm) pitch. The 2.54 mm grid is the most widely used spacing for discrete-signal connectors, ensuring broad mating compatibility with dual-row pin headers, IDC crimps, and development-board expansion headers available from multiple manufacturers.
In what assembly scenarios does a horizontal SMT socket like SMH-113-02-F-S-TR outperform a vertical through-hole header?
Horizontal SMT sockets shine when the enclosure height budget is tight. A vertical through-hole header requires clearance equal to its own mated height (typically 8 mm to 12 mm above the PCB), whereas a horizontal SMT socket limits the height to the mating connector's body depth, often under 5 mm. Additionally, SMT eliminates 26 drilled through-holes, cutting PCB fabrication cost and freeing inner-layer routing space in multilayer boards.
What does the F suffix in SMH-113-02-F-S-TR indicate about the contact finish?
In Samtec SMH series nomenclature, the F suffix designates gold-flash contact plating on the mating surfaces, typically 0.2 µm to 0.38 µm of gold over nickel. Gold flash provides lower contact resistance and better corrosion resistance than matte tin at a modest cost premium, making it suitable for applications with fewer than 50 mating cycles such as field-replaceable modules where long-term contact integrity matters more than high insertion-cycle life.
When should an engineer consider SMH-113-02-F-S-TR over a larger SMH-136-02-S-S-TR for a board-to-board interface?
SMH-113-02-F-S-TR is the right choice when the interface requires only 26 signals, because using a 72-contact connector for fewer signals wastes PCB area and raises unit cost. The 13-position, 2-row body is approximately 33 mm long versus 91 mm for a 36-position strip, a difference of nearly 58 mm that matters in compact boards under 100 mm × 100 mm. Choose the larger 36-position strip only when the signal count genuinely demands 48 or more connections.
