Frequently Asked Questions
How does the horizontal mount orientation of the SMH-123-02-FM-S-TR benefit space-constrained PCB designs?
The horizontal surface-mount orientation positions the mating interface parallel to the PCB surface, reducing the overall height of the connector assembly. For SMH-123-02-FM-S-TR at 0.100" pitch with 46 positions, this allows board-to-board connections in enclosures with vertical clearances as low as 8 mm, which is useful in slim industrial controllers and compact embedded modules.
What does the floating-mount (FM) designation mean for assembly and mating reliability in the SMH-123-02-FM-S-TR?
The FM designation means the contact housing can shift laterally by approximately ±0.5 mm to compensate for PCB misalignment during board mating. This reduces solder joint stress and mechanical binding across 46 positions, improving connector reliability over repeated mating cycles and reducing field failures in applications where board-to-board alignment tolerance is difficult to control.
For which applications is the SMH-123-02-FM-S-TR a suitable single-row 0.100" pitch socket?
The SMH-123-02-FM-S-TR is suitable for connecting peripheral boards, sensor modules, and I/O expansion cards to a main PCB in industrial control, embedded computing, and instrumentation systems. Its 46-position single-row 0.100" pitch layout is compatible with standard dual-in-line header pins, supporting mixed digital and analog signal routing at up to 1 A per contact in a compact horizontal form factor.
