What are the key features of SMH-129-02-TM-S-TR?
- 0.100" (2.54 mm) pitch horizontal SMT socket strip enables compact side-entry board connections in space-constrained enclosures
- Single-row 29-position layout provides flexible signal routing for embedded and industrial control boards
- Tape-and-reel (TR) packaging ensures compatibility with automated pick-and-place assembly for high-volume PCB production
What is SMH-129-02-TM-S-TR used for?
SMH-129-02-TM-S-TR is well suited for horizontal board-edge socket connections in embedded control systems, industrial I/O modules, and consumer electronics where side-access connectivity is required at standard 2.54 mm pitch. Its surface-mount footprint and tape-and-reel packaging make it highly compatible with automated SMT production lines, reducing assembly time and cost in medium-to-high-volume manufacturing. The 29-position single-row format is also practical for signal interface headers on test and measurement daughterboards requiring reliable yet removable connections.

Frequently Asked Questions
What is the contact pitch and position count of SMH-129-02-TM-S-TR, and how does this suit standard logic-level interface designs?
The SMH-129-02-TM-S-TR has a 0.100" (2.54 mm) pitch with 29 contact positions in a single-row surface-mount configuration. This standard pitch aligns with common 2.54 mm header systems, making it directly compatible with logic-level interface designs operating at 3.3 V or 5 V on embedded control and industrial I/O boards.
How does the horizontal orientation of SMH-129-02-TM-S-TR benefit panel-mount or enclosure-integrated PCB assemblies?
The horizontal (side-entry) orientation of SMH-129-02-TM-S-TR directs the 29 contacts at 90 degrees to the PCB plane, enabling front-panel or enclosure-wall connector access without increasing board height. This is especially beneficial in compact enclosures where vertical clearance is limited to under 10 mm and edge-access cable connections are preferred.
When should SMH-129-02-TM-S-TR be chosen over through-hole socket strips for high-volume production?
SMH-129-02-TM-S-TR is preferred over through-hole alternatives in high-volume production because its SMT footprint and tape-and-reel (TR) packaging support automated pick-and-place assembly at speeds exceeding 10,000 placements per hour. Through-hole versions require manual insertion or wave soldering, adding process steps and cost that SMT avoids on modern reflow lines.
What current rating per contact does SMH-129-02-TM-S-TR support, and how many contacts can be used for power in a mixed signal design?
Each contact in the SMH-129-02-TM-S-TR is rated at approximately 1 A at 2.54 mm pitch, with contact resistance typically below 30 mΩ. In a mixed-signal design with 29 positions, several contacts can be dedicated to power rails such as 3.3 V or 5 V while the remaining contacts carry digital or analog signals, providing flexible power-signal partitioning.
