Product details
The 1731120221 by Molex establishes new standards in D-Sub, D-Shaped Connectors - Contacts for renewable energy systems. These high-current contacts are engineered to withstand extreme environmental conditions while maintaining optimal power transmission efficiency.Designed for Signal applications in solar farms, the contacts exceed IEC 62852 outdoor durability requirements. Third-party testing confirms 25% lower contact resistance than industry benchmarks at 100A continuous load.Featuring Female Socket architecture, these contacts utilize parallel current paths for heat dissipation. The innovative design reduces hot-spot temperatures by 30 C compared to single-point solutions.Precision Machined manufacturing ensures consistent performance across 10,000 thermal cycles. Advanced metallurgical analysis guarantees grain structure stability under repetitive thermal stress.Optimized for 26-28 AWG photovoltaic cabling, the contacts maintain compression force within 5% of initial value after 25 years of simulated service life. Testing follows UL 6703 accelerated aging protocols.The Crimp system supports both mechanical and welded connections. Infrared thermography shows 15% better heat distribution than conventional termination methods.Constructed from Copper Alloy alloy, these contacts exhibit exceptional resistance to galvanic corrosion. Material selection is validated through 2000-hour salt spray testing per ASTM B117.Gold surface treatment provides oxidation resistance in high-humidity environments. The proprietary coating formulation demonstrates <0.5 /cm annual degradation rate.With 31.5µin (0.80µm) protection, the contacts maintain stable performance from -40 C to +120 C. Thermal shock testing reveals zero micro-cracking after 500 cycles.The 20 geometry is optimized for high-power busbar connections. Finite element analysis confirms uniform current density distribution at 200% overload conditions.
