Engineered for high-density, reliable connections, the Molex 503948100 & 51110151192 terminal wire harness integrates the Milli-Grid terminal series with A2005HA dual-side buckle housing, delivering exceptional performance in compact electronic systems. This 2.0mm pitch Dupont-compatible solution combines precision crimp terminals, robust locking mechanisms, and industry-leading material science to ensure secure signal and power transmission across consumer electronics, industrial equipment, and automotive applications.
Core Features
✅ Dual-Side Buckle Locking System
Bi-directional positive latches with audible click confirmation ensure vibration-resistant mating
Prevents accidental disconnection in high-motion environments (15g vibration tolerance)
Polarized housing design eliminates reverse insertion risks
✅ Premium Conductivity & Durability
503948100 terminals: 0.38μm gold-plated copper alloy contacts (≤20mΩ contact resistance)
Nickel-plated termination (2.0μm minimum) enhances crimp stability and corrosion resistance
PBT UL94V-0 housing withstands -40℃ to 105℃ operating temperatures
✅ Space-Efficient High-Density Design
2.00mm pitch enables 30% more connections in limited PCB space vs. 2.54mm alternatives
Supports 24-30AWG wires (max insulation diameter 1.40mm) for flexible routing
Dual-row configuration (51110151192 housing) expands circuit capacity while maintaining compact footprint
✅ Versatile Compatibility & Easy Installation
Dupont 2.0mm pitch compatible with standard headers and receptacles
