Key Features
- 28-position single-row socket strip on 0.100 inch (2.54 mm) pitch offers broad compatibility with standard 2.54 mm male headers and pin strips
- Horizontal surface-mount orientation delivers low connector height above the PCB, enabling compact stackable and panel-edge designs
- Female contact (-F) design with tape-and-reel (-TR) packaging supports automated pick-and-place and lead-free reflow soldering in SMT production
Applications
The SMH-128-02-F-S-TR is suited for board-edge and panel-access socket applications in industrial controllers, embedded single-board computers, and laboratory instruments where a 0.100 inch pitch interface is required. Its 28-position single-row layout supports I/O expansion headers, peripheral interfaces, and signal routing to external modules or ribbon cables. The horizontal SMD orientation minimizes height above the PCB, making it suitable for slim enclosures and stacked PCB assemblies with clearances as tight as 8 mm.

Frequently Asked Questions
How many contacts does the SMH-128-02-F-S-TR provide and what pitch does it use?
The SMH-128-02-F-S-TR provides 28 positions in a single-row configuration on a 0.100 inch (2.54 mm) pitch. This standard pitch ensures direct compatibility with a wide range of 2.54 mm male pin headers, DIP modules, ribbon cable connectors, and prototyping components used across embedded computing and industrial electronics platforms.
What design advantage does the horizontal surface-mount orientation provide for board clearance?
The horizontal (side-entry) orientation positions the mating aperture parallel to the PCB surface, reducing the height above the board compared to vertical SMD socket strips. This allows the SMH-128-02-F-S-TR to function within enclosures or stacked board assemblies where connector height must stay below 8 mm, while still providing 28 fully accessible signal contacts at the board edge.
Can SMH-128-02-F-S-TR be used in automated SMT production and what soldering process applies?
Yes, the -TR suffix indicates tape-and-reel packaging for automated pick-and-place machines, and the surface-mount termination is designed for reflow soldering. SAMTEC SMH series connectors are compatible with lead-free solder profiles peaking at 260°C, meeting J-STD-020 standards and enabling single-pass reflow assembly alongside other SMD components on the same board.
How does SMH-128-02-F-S-TR differ from a through-hole socket strip when designing for multi-layer PCBs?
A through-hole socket strip requires 28 drilled holes of 0.8 mm to 1.0 mm diameter, consuming via space on all PCB layers beneath the connector. The SMH-128-02-F-S-TR surface-mount version requires no through-holes, preserving all inner routing layers — typically 2 to 6 layers in a standard multilayer board — under the connector footprint, allowing denser signal routing on boards where layer count is fixed.
