EV Backup Terminal Series M18-2+6 High Power 500V 20A Durable Charging Connector
EV Backup Terminal Series M18-2+6 High Power 500V 20A Durable Charging Connector
Product Definition
The M18-2+6 Series is a robust circular power charging and discharging connector designed for high-reliability applications. It features a 2+6 pin configuration (2 large power pins + 6 signal/small pins) and is available in both male (plug) and female (receptacle) versions. The connector supports AC power transmission with excellent environmental resistance, making it ideal for industrial charging systems, energy storage, and electric equipment interfaces.
Key Features
- High Power Handling: Rated for 500V AC with 20A on large terminals and 3A on small terminals.
- Excellent Environmental Durability: Wide operating temperature range (-25°C to +70°C) and high humidity tolerance (95% at 40°C).
- Long Service Life: ≥3,000 mating cycles with strong insertion force (20.60N).
- Superior Safety & Insulation: Low contact resistance (≤10mΩ), high insulation resistance (≥100MΩ), and UL94-V0 flame retardant rating.
- Compact & Reliable Design: Robust housing with clear dimensional drawings for easy integration.
- Versatile Connectivity: Supports both panel-mount receptacles and cable assemblies with multiple wire configurations.
