What are the key features of SMH-128-02-FM-S-TR?
- 28-position single-row layout on 0.100" (2.54 mm) pitch accepting standard pin headers across a 69 mm contact span
- Horizontal surface-mount orientation enabling board-edge socket access while minimizing vertical PCB clearance requirements
- Female metal (FM) socket contacts delivering consistent normal force and reliable mating with 0.100" square pin headers
- Tape-and-reel (TR) format supporting automated pick-and-place SMT assembly at high production volumes
What is SMH-128-02-FM-S-TR used for?
The SMH-128-02-FM-S-TR is designed for single-board computers, development modules, and industrial I/O expansion boards where a 28-pin horizontal socket provides accessible edge connectivity without adding vertical height. Its SMT footprint integrates into standard reflow solder processes, enabling cost-effective high-volume assembly. Low-speed digital signal interfaces, sensor break-out boards, and field-wiring interface cards all benefit from this connector's accessible horizontal mating direction.

Frequently Asked Questions
How many positions does SMH-128-02-FM-S-TR contain, and what is its overall contact span on a PCB?
SMH-128-02-FM-S-TR has 28 positions on a single row with a 0.100 inch (2.54 mm) pitch, giving a total contact span of approximately 69 mm. This length accommodates 28 individual signal lines while remaining within the board-edge footprint of typical SBC or expansion card designs.
What PCB assembly process is SMH-128-02-FM-S-TR optimized for, and how does tape-and-reel help?
SMH-128-02-FM-S-TR is optimized for automated surface-mount assembly using pick-and-place machines. The TR tape-and-reel format packages individual connectors at precise intervals on carrier tape, enabling placement rates of hundreds of parts per hour and reducing manual handling on 28-position socket placement steps.
In what way does the horizontal orientation of SMH-128-02-FM-S-TR differ from a vertical SMT socket, and when should it be chosen?
The horizontal orientation of SMH-128-02-FM-S-TR directs mating insertion parallel to the PCB surface rather than perpendicular to it, reducing the above-board height to a few millimeters versus the pin-height of a vertical 0.100 inch socket. Choose the horizontal variant when enclosure lid clearance above the PCB is under 10 mm or when connectors must be accessible from the board edge after installation.
