J-SP2140(LF)(SN)

The J-SP2140(LF)(SN) by JST Sales America Inc. 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 Male Pin 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 Stamped manufacturing ensures consistent performance across 10,000 thermal cycles. Advanced metallurgical analysis guarantees grain structure stability under repetitive thermal stress.Optimized for 24-28 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 Brass 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 Flash protection, the contacts maintain stable performance from -40 C to +120 C. Thermal shock testing reveals zero micro-cracking after 500 cycles.The Tin plating ensures reliable connections in corrosive atmospheres. Testing with ammonia vapor shows 10x better corrosion resistance than standard tin finishes.Incorporating Insulation Support, the design achieves IP68 protection against dust and water ingress. Pressure testing confirms 2 bar water resistance for 24 hours continuous immersion.
