The HMK70-002.2-F is a heavy-duty industrial circular connector engineered for high-power transmission in demanding applications like industrial machinery, power distribution, and renewable energy systems. Designed to accommodate 14-22mm² cables, it features a rugged IP68-sealed housing that provides superior protection against dust, water immersion, and extreme vibration, ensuring stable operation across temperatures from -40°C to +125°C.
Equipped with a 2-pin configuration and crimp termination, this connector delivers reliable high-current connections rated at 70A/690V AC, ideal for heavy-duty power transmission. Its silver-plated copper contacts minimize contact resistance and heat generation, while the corrosion-resistant brass shell with nickel plating enhances durability, supporting over 5,000 mating cycles for long-term, low-maintenance performance.
Compatible with standard industrial mounting protocols, the HMK70-002.2-F enables secure, tool-assisted installation for efficient assembly. Compliant with global safety standards (IEC 60309) and EMC requirements, it combines robust construction with precise power transmission capabilities, making it the ideal choice for critical high-power applications in harsh industrial environments.
