What are the key features of SMH-131-02-TM-S-TR?
- 0.100-inch (2.54 mm) pitch horizontal surface mount orientation provides right-angle board edge socket connections without requiring through-hole PCB drilling
- 31-position single-row socket strip offers a long-span, high-channel-count edge interface with gold-plated contacts rated for reliable multi-cycle mating performance
- Tape-and-reel (-TR) packaging ensures compatibility with standard SMT pick-and-place equipment for accurate, repeatable high-volume automated PCB assembly
What is SMH-131-02-TM-S-TR used for?
The SMH-131-02-TM-S-TR serves as a horizontal board edge socket in industrial I/O expansion panels, embedded computing backplanes, and test instrumentation front panels requiring 31-position SMT socket connections at standard 0.100-inch pitch. Its right-angle profile routes signals parallel to the PCB surface, making it ideal for daughter cards that plug in horizontally along a board edge. Tape-and-reel delivery enables efficient pick-and-place processing across high-volume production runs of edge-mount socket assemblies.

Frequently Asked Questions
What pitch and position count makes SMH-131-02-TM-S-TR suitable for wide board-edge socket interfaces?
The SMH-131-02-TM-S-TR features 0.100-inch (2.54 mm) pitch with 31 single-row positions, spanning a total footprint length of approximately 78.7 mm (31 x 2.54 mm). This wide single-row horizontal socket is suited for board-edge interfaces needing more than 25 signal channels at standard pitch without the added PCB width of a dual-row layout.
In which industrial or embedded computing applications does a 31-position horizontal SMT socket strip provide the best fit?
A 31-position horizontal SMT socket at 0.100-inch pitch is well-suited for industrial PLC expansion modules routing 31 digital I/O signals along a board edge, embedded single-board computer interface headers, laboratory instrument front-panel signal connectors, and backplane-to-daughter-card interfaces operating at signal voltages up to 5 V in environments from -40°C to +85°C.
How does the SMH-131-02-TM-S-TR differ from a vertical through-hole socket strip of the same pin count and pitch?
The SMH-131-02-TM-S-TR is a surface mount right-angle (horizontal) variant, eliminating through-hole PCB drilling for 31 contacts at 2.54 mm pitch, whereas a vertical through-hole socket requires drilled plated holes through all PCB layers. The SMT version reduces PCB layer disruption, supports automated placement, and allows board-edge mounting where vertical height above the PCB must be minimized for slim enclosure designs.
