The gold mating finish (flash thickness) on the male pins provides a corrosion-resistant interface for repeated mating cycles — expect several hundred cycles before contact resistance drifts, which is fine for field-serviceable equipment or modular assemblies that get disconnected quarterly. Surface-mount termination with a latch holder fastening type means the header locks positively to the mating receptacle once mated. In a vibration-prone environment — say, inside an industrial controller or a test fixture — the latch prevents the pair from backing apart.
2.00 mm Pitch, 48 Circuits — Board Layout and Routing
For a 48-position dual-row header, the outer pin span is roughly 47 × 2.00 mm = 94 mm between the first and last pin centers, plus the shroud overhang. This allows routing two traces between adjacent pins on a standard 1 oz copper layer with 0.20 mm trace/space — common for signal-level routing without resorting to fine-line PCB fabrication. The SMT pads should be laid out per the manufacturer's footprint drawing to ensure solder joint reliability — the 4-wall shroud adds some keep-out area around the perimeter that the board layout must accommodate.
The header is RoHS-compliant per the manufacturer's declaration.
The SMT termination requires reflow soldering; the header is supplied in bulk (tube or tray), so pick-and-place handling may need a custom nozzle for the shroud.
