Key Features
- Horizontal surface-mount orientation allows low-profile board-edge mating with 0.100 inch (2.54 mm) pitch header pins, saving vertical clearance in space-constrained assemblies
- 2-position single-row layout provides a compact minimal-footprint socket for dedicated 2-wire power, signal, or programming interface connections on PCBs
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly for consistent high-volume production of PCB socket connector placements
Applications
The SMH-102-02-TM-S-TR is used in PCB designs requiring a low-profile horizontal 2-pin socket for interfacing with standard 0.100 inch pitch header connectors in test, programming, or power connection applications. Its surface-mount, tape-and-reel format suits automated assembly lines producing consumer electronics, industrial control boards, and development modules where repeatable connector placement is needed. The 2-position configuration is common in UART, I2C, SWD debug header interfaces, and small power connector footprints on embedded system PCBs.

Frequently Asked Questions
What pin pitch and position count does SMH-102-02-TM-S-TR provide for PCB header mating?
The SMH-102-02-TM-S-TR is a 2-position single-row socket with 0.100 inch (2.54 mm) pin pitch, making it directly compatible with standard 0.100 inch header pins used on breadboards, Arduino shields, and general-purpose PCB connectors. The 2-position count suits dedicated 2-wire interface connections such as power rails, UART TX/RX pairs, or I2C SDA/SCL lines.
How does the horizontal surface-mount orientation of SMH-102-02-TM-S-TR benefit low-profile PCB designs?
The horizontal mounting orientation keeps the mating axis parallel to the PCB surface, reducing the assembled connector height to a few millimeters above the board compared to vertical through-hole sockets that add 8 mm or more in height. This is advantageous in thin portable devices, panel-mount boards, and enclosures with tight lid clearance where vertical header connectors would exceed the available height budget.
Can SMH-102-02-TM-S-TR be used as a SWD or JTAG debug header socket in a production embedded system?
Yes, the 2-position 0.100 inch pitch SMH-102-02-TM-S-TR can serve as a compact programming or debug socket for 2-wire interfaces such as SWD SWDIO/SWDCLK or simplified 2-pin UART debug ports. Its SMT format allows it to be included in the standard assembly process, and the horizontal orientation enables edge-accessible mating with a debug probe cable without requiring the probe connector to stand vertically above the PCB surface.
What assembly advantages does the tape-and-reel format of SMH-102-02-TM-S-TR offer compared to bulk-packaged sockets?
The TR (tape-and-reel) format feeds connectors to pick-and-place machines at a controlled rate, eliminating manual feeder loading and reducing placement errors compared to bulk-tray or loose-piece packaging. For production runs of hundreds or thousands of boards, tape-and-reel reduces assembly labor, maintains consistent SMT placement accuracy within ±0.1 mm, and enables lights-out automated SMT lines without manual intervention for connector loading.
