What are the key features of SMH-127-02-L-S-TR?
- 0.100 inch (2.54 mm) pitch dual-row horizontal SMT socket with 54 total contacts for versatile board interconnect solutions
- Horizontal surface-mount orientation reduces connector stack height compared to vertical through-hole alternatives for slim enclosure designs
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly, reducing placement cycle time in high-volume production
- Standard 0.100 inch grid ensures broad mating compatibility with common pin headers, IDC connectors, and development board accessories
What is SMH-127-02-L-S-TR used for?
The SMH-127-02-L-S-TR is suited for board-to-board and module-to-baseboard signal interconnects requiring a 54-contact, 0.100 inch pitch horizontal socket in a compact SMT footprint. Industrial control systems, embedded computing expansion cards, and test-and-measurement daughterboards benefit from its dual-row layout where many I/O signals must be routed between stacked PCBs in a confined space. Its tape-and-reel delivery makes it cost-effective for automated SMT lines producing medium- to high-volume assemblies.

Frequently Asked Questions
How many contacts does SMH-127-02-L-S-TR provide and at what pitch?
The SMH-127-02-L-S-TR is a 27-position, 2-row socket strip with 54 total contacts arranged on a 0.100 inch (2.54 mm) pitch. The standard 2.54 mm grid is compatible with a wide range of off-the-shelf dual-row pin headers, ribbon-cable connectors, and development-platform GPIO headers used in both prototype and production designs.
For a low-profile embedded system, how does the horizontal SMT orientation of SMH-127-02-L-S-TR save vertical clearance?
Mounting the socket horizontally keeps the mating connector lying parallel to the PCB, so the tallest point above the board is determined by the mating plug body rather than a vertical pin-header protrusion. In practice this can reduce the PCB-to-PCB stack height by 5 mm to 10 mm compared to a vertical through-hole header, a critical saving in slim enclosures where total assembly thickness is below 20 mm.
What does the tape-and-reel packaging mean for procuring SMH-127-02-L-S-TR in production quantities?
The TR suffix means parts are supplied on a continuous tape reel sized for automated SMT pick-and-place machines. Reels typically hold 500 to 1000 connectors, minimizing manual kitting labor and ensuring consistent feeder orientation for placement accuracy. For production runs of 200 or more assemblies, tape-and-reel is generally more cost-effective per unit than cut-tape or tray packaging.
What mating connectors are compatible with SMH-127-02-L-S-TR for a 54-pin board-to-board interface?
The SMH-127-02-L-S-TR accepts standard 0.100 inch dual-row pin headers such as Samtec TSW-127 or compatible 27-position, 2-row headers from other manufacturers. The 2.54 mm pitch also accommodates standard 54-pin IDC ribbon-cable plugs, giving designers flexibility to route signals over flat cables rather than committing to a direct board-to-board stack configuration.
