A3EA-50D-2R(41)

Hirose Electric Co Ltd's A3EA-50D-2R(41) establishes new benchmarks in Rectangular Connectors - Free Hanging, Panel Mount for renewable energy systems. This robust connectivity solution is specifically designed for solar inverters, wind turbine controls, and energy storage systems, featuring exceptional environmental resistance and long-term reliability.The Receptacle configuration incorporates UV-resistant materials rated for 25-year outdoor exposure. The double-sealed design maintains IP68 protection even after 500 mating cycles in dusty environments.Utilizing Female Socket technology, these power contacts exhibit 50% lower thermal resistance than industry standards. The bulk material design eliminates joint interfaces that could degrade over time.Available in 50 hybrid configurations, the connector combines power and signal contacts in optimized ratios. The segregated contact groups prevent electromagnetic interference between circuit types.The 0.079" (2.00mm) spacing provides sufficient creepage distance for 1500V DC systems. The molded ribs between contacts prevent tracking in humid conditions per IEC 60664.The 2 row arrangement positions power contacts on the outer rows for optimal heat dissipation. This thermal management design reduces hot-spot temperatures by up to 15 C.0.079" (2.00mm) separation between power and signal contacts prevents capacitive coupling. This isolation is critical for accurate current measurement in smart inverters.The Free Hanging (In-Line) version includes integrated cable glands for strain relief. The corrosion-resistant aluminum housing meets NEMA 4X requirements for harsh outdoor installations.The Friction Lock mechanism requires specific tooling for operation, preventing unauthorized access. The captive screws ensure no components are lost during maintenance.Featuring IDC technology, the system accommodates both fine-strand and solid conductors. The torque-limited screw terminals prevent over-tightening during field installation.Compatible with Ribbon Cable photovoltaic cables, the contacts maintain stable resistance through 1000 thermal cycles. The silver-plated termination surfaces resist sulfidation in polluted atmospheres.The Feed Through include integrated surge arrestors for overvoltage protection. These built-in devices clamp transient voltages below equipment withstand levels.The Galvanized plating exceeds 1000 salt spray hours per ASTM B117. The micro-roughened surface increases contact area while maintaining low insertion force.The Black housing incorporates temperature-sensitive color indicators. These visual cues alert maintenance personnel to potential overheating conditions.
