What are the key features of SMH-135-02-SM-S-TR?
- 70-position single-row 0.100" pitch layout provides a wide signal interface in a compact horizontal SMT footprint
- Horizontal surface-mount (SM) termination enables low-profile board-edge connections compatible with standard SMT reflow processes
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place assembly with consistent orientation
What is SMH-135-02-SM-S-TR used for?
The SMH-135-02-SM-S-TR is suited for board-to-board and board-to-module signal interconnects in embedded computing, industrial automation, and consumer electronics where a low-profile horizontal interface is required. Its 70-position single-row 0.100" pitch design provides a large signal count in a standardized footprint, compatible with common 0.100" pitch header counterparts. The SMT termination style enables co-planar soldering during standard reflow assembly, reducing manufacturing complexity.

Frequently Asked Questions
How many positions does the SMH-135-02-SM-S-TR offer, and how does that compare to lower pin count alternatives in the SMH series?
The SMH-135-02-SM-S-TR provides 70 positions in a single-row 0.100" pitch layout, which is significantly more than the 46-position SMH-123-02-SM-S-TR. This higher position count suits applications needing wide parallel buses, mixed signal and power routing, or expanded I/O interfaces within a single horizontal connector rather than using multiple smaller connectors.
What is the significance of the SM (surface mount) termination in the SMH-135-02-SM-S-TR for PCB assembly?
The SM termination means the connector uses SMT solder tails that sit flush on PCB pads and are soldered during standard reflow assembly, eliminating the need for through-hole drilling. This simplifies the PCB fabrication process, reduces board thickness requirements, and allows the SMH-135-02-SM-S-TR to be placed at board heights as low as 3.9 mm in a horizontal orientation compatible with automated SMT lines.
In which system categories does a 70-position horizontal socket like the SMH-135-02-SM-S-TR provide clear design advantages?
A 70-position horizontal socket at 0.100" pitch is advantageous in industrial controllers with large I/O expansion cards, embedded SBCs requiring connection to peripheral modules, and data acquisition systems needing 70 or more analog and digital signal channels in a single compact connector. The horizontal orientation keeps the mated connector height profile below 12 mm, fitting within standard DIN-rail enclosure form factors.
