Key Features
- 0.100 inch (2.54 mm) standard pitch with 27 single-row positions offering broad compatibility with industry-standard pin headers in horizontal board-edge connections
- Floating mount (FM) design tolerating up to ±0.3 mm PCB misalignment in X and Y axes to ease board-to-board assembly stack-up tolerances
- Tape-and-reel (TR) packaging supporting automated pick-and-place SMT assembly at high production volumes with consistent orientation control
Applications
The SMH-127-02-FM-S-TR is suited for horizontal board-to-board signal interconnection in embedded computing systems, industrial panel controllers, and test-and-measurement rack modules where adjacent PCBs connect at a 90-degree angle. Its 27-position single-row layout and floating mount accommodate alignment variations inherent in multi-board chassis assemblies, reducing connector stress and preventing solder joint failure over the product lifetime. The surface-mount construction and tape-and-reel packaging enable cost-effective high-volume SMT production without manual connector insertion.

Frequently Asked Questions
How many contact positions does the SMH-127-02-FM-S-TR provide and what connector pitch does it use?
The SMH-127-02-FM-S-TR provides 27 positions in a single-row layout on a 0.100 inch (2.54 mm) pitch, yielding 27 contact points per connector. This standard pitch ensures direct mating compatibility with the majority of SAMTEC and industry-standard 2.54 mm pin headers, simplifying connector selection for horizontal board-to-board interfaces in embedded systems, backplane expansions, and cable assembly harnesses.
What advantage does the floating mount feature provide when assembling the SMH-127-02-FM-S-TR in a multi-board chassis?
The FM (floating mount) feature of the SMH-127-02-FM-S-TR allows the connector housing to self-align by up to ±0.3 mm in X and Y directions, compensating for PCB positional variation caused by chassis hole tolerances, PCB warp, and thermal expansion differentials across the -40°C to +85°C operating range. Without this float, a rigid 27-pin horizontal connector would impose stress on SMT solder joints during board installation into fixed standoff chassis, risking joint cracking over time.
How does the horizontal orientation of the SMH-127-02-FM-S-TR differ from vertical socket strips in board-to-board applications?
The horizontal orientation of the SMH-127-02-FM-S-TR routes the 27-pin mating interface parallel to the PCB surface, connecting two boards positioned edge-to-edge at a 90-degree angle with a combined stack height under 8 mm. Vertical socket strips instead stack boards directly on top of each other with a mating axis perpendicular to the PCB surface, increasing assembly height by 10 mm or more. The horizontal approach is preferred in slim panel designs, side-mounting daughtercards, and enclosures where total assembly height is constrained below 15 mm.
