Application & Advantages

• Designed for solar photovoltaic and energy storage systems requiring high-current, sealed outdoor connections.
• Robust bayonet locking with audible/tactile feedback for high-vibration and outdoor environments.
• High-reliability sealing (IP67) for temporary immersion resistance and dustproof performance; higher IP levels (IP68/IP69K) available as customization.
• Housing materials with UL94 V-0 flame-retardant rating and structural impact resistance for industrial use.
• High mating cycle durability (500+ mating cycles), reducing maintenance and replacement frequency.
