What are the key features of SMH-102-02-SM-S-TR?
- Horizontal surface-mount orientation positions the mating opening parallel to the PCB, enabling right-angle plug insertion for space-efficient edge-connection layouts
- Phosphor bronze contacts with tin-over-nickel barrier finish provide reliable low-resistance mating with resistance to fretting corrosion across the connector's service life
- 0.100" (2.54 mm) pitch single-row 4-position layout is compatible with standard 0.1" grid headers and ribbon cables widely used in prototyping and production boards
What is SMH-102-02-SM-S-TR used for?
SMH-102-02-SM-S-TR is used in horizontal board-to-cable connections, right-angle daughtercard sockets, and PCB edge interface points where vertical connectors would exceed enclosure height limits. Its phosphor bronze single-row socket design accepts standard 0.100" pitch male headers or jumper pins, making it suitable for programming interfaces, small signal expansion headers, and sensor module connections in consumer electronics and industrial embedded boards.

Frequently Asked Questions
What does the horizontal SMT orientation of SMH-102-02-SM-S-TR mean for PCB layout?
The horizontal (H) orientation means the socket opening faces parallel to the PCB plane rather than perpendicular, so mating headers or cable connectors insert from the board's side edge rather than from above. This reduces the assembled connector height above the board to approximately 5.94 mm (0.234 inch body depth), beneficial in flat enclosures with under 8 mm clearance above the PCB surface where vertical socket strips would not fit.
What contact material and finish does SMH-102-02-SM-S-TR use and why does that matter for signal integrity?
The SMH-102-02-SM-S-TR uses phosphor bronze contacts with a tin (Sn) over nickel (Ni) barrier finish. The nickel barrier prevents tin diffusion into the base metal, maintaining stable contact resistance below 50 mΩ over the connector's rated insertion cycle life. This finish is suitable for low-frequency digital signals and power distribution at operating temperatures from -55°C to +125°C without gold plating cost.
How many positions and what pitch does SMH-102-02-SM-S-TR provide, and what headers mate with it?
The SMH-102-02-SM-S-TR is a 4-position single-row connector at 0.100" (2.54 mm) pitch, mating with standard 0.100" pitch single-row male headers, square-post pins, and breakaway header strips used widely in Arduino-compatible boards and embedded development platforms. The 4-position configuration spans 10.16 mm (4 × 2.54 mm) of connector length, fitting standard 4-pin interface footprints for UART, SPI, I2C, or power header connections.
When would a designer choose SMH-102-02-SM-S-TR over a vertical SMT socket strip for the same 4-pin interface?
A horizontal socket is chosen when the PCB sits close to an enclosure wall or panel and cables must route laterally rather than vertically out of the connector. For example, in a device with only 6 mm clearance above the PCB, the SMH-102-02-SM-S-TR's 0.47 inch (11.94 mm) horizontal depth fits within the lateral board space while a vertical 4-pin socket requiring 8 mm height above the board would physically interfere with the enclosure lid.
