What are the key features of SMH-129-02-L-S-TR?
- 0.100 inch (2.54 mm) pitch 29-position single-row horizontal surface mount socket strip enabling right-angle wire-to-board or board-to-board connections on standard grid PCBs
- Low-profile horizontal (L) orientation reduces connector height above the PCB surface, ideal for slim enclosures or chassis with limited vertical clearance
- Tape-and-reel (TR) packaging with surface mount termination supports high-volume automated pick-and-place and reflow soldering on 0.100 inch pitch pads
What is SMH-129-02-L-S-TR used for?
The SMH-129-02-L-S-TR is used in consumer electronics, industrial control panels, and communication equipment where a 29-position horizontal socket strip at 0.100 inch pitch provides right-angle mating to keep mated connectors parallel to the PCB surface. Its low-profile horizontal mounting reduces total assembly height, making it suitable for slim portable devices and panel-mount chassis connectors. Tape-and-reel format enables automated SMT assembly with consistent placement accuracy on standard 100-mil grid board layouts.

Frequently Asked Questions
How many positions does the SMH-129-02-L-S-TR provide and what is its pitch?
The SMH-129-02-L-S-TR is a 29-position single-row socket strip with a 0.100 inch (2.54 mm) pitch, accommodating up to 29 individual signal or power connections in a horizontal surface mount layout along a standard 100-mil PCB grid.
What does the horizontal (L) suffix mean for SMH-129-02-L-S-TR and when is it preferred over a vertical mount socket?
The L suffix indicates a horizontal or right-angle orientation, meaning the mating direction is parallel to the PCB surface rather than perpendicular. This is preferred in slim enclosures with less than 10 mm of vertical clearance above the board, where a vertical 29-position socket strip would exceed available chassis height in the 0.100 inch pitch SMT layout.
Which current and voltage ratings does the SMH-series 0.100 inch socket strip support for industrial control applications?
SAMTEC SMH-series 0.100 inch pitch socket strips are typically rated for up to 3 A per contact and 250 V AC/DC, supporting industrial 24 V control signal wiring, 5 V logic buses, and 12 V power distribution across all 29 positions without exceeding the connector's thermal or dielectric limits.
Is the SMH-129-02-L-S-TR compatible with standard lead-free reflow soldering and what packaging format does it use?
Yes, the SMH-129-02-L-S-TR ships in tape-and-reel (TR) format and is compatible with lead-free reflow soldering at peak temperatures up to 260 degrees C per JEDEC J-STD-020. The tape-and-reel format allows automated pick-and-place equipment to feed and place the 29-position socket strip on 0.100 inch SMT pads without manual component loading.
