Product Specifications
1. Core High-Power Electrical Specifications
This M25 2-core circular watertight electrical connector features a rated current of 50A, rated voltage of 600V, and withstand voltage up to 2500V AC. It provides stable conductivity and strong load-bearing capacity, supporting continuous power supply for various medium and high-power electrical equipment. It effectively prevents power outage, overheating, and short circuit faults under high-load operation, making it perfectly suitable for long-term and high-frequency power supply scenarios.
2. Premium PA66 Plastic Housing, Flame Retardant & Durable
The connector shell is integrally molded with high-strength PA66 nylon engineering plastic, reaching UL94-V0 flame retardant grade with excellent fireproof and explosion-proof performance. It boasts outstanding anti-aging, anti-impact, high and low temperature resistance, as well as acid and alkali corrosion resistance. It resists erosion from harsh outdoor environments, industrial dust and oil stains, without deformation, cracking or aging after long-term service, greatly extending service life.
3. IP67 Waterproof & Dustproof Protection
Adopting a precision sealing rubber ring and buckle locking sealing structure, the connector achieves IP67 waterproof and dustproof rating. It effectively blocks rainwater, moisture, dust and fog invasion, adapting to complex working conditions such as open-air exposure, underwater use and humid workshops. It ensures stable and safe electrical connection and prevents circuit failures caused by water and dust ingress.
4. High-Conductivity Copper Alloy Contacts
Built-in high-precision copper alloy conductive contacts feature excellent conductivity and low resistance with minimal power loss during transmission. Capable of stably carrying 50A high current continuously, the contacts are treated with anti-oxidation and anti-plating processes. They are wear-resistant, plug-resistant and not easy to rust or oxidize, maintaining tight fitting after repeated plugging and unplugging to avoid poor contact and overheating, ensuring efficient and safe power transmission.
5. Quick Lock Structure for Easy & Firm Installation
Designed with push-pull quick locking structure, the connector is easy to plug and unplug without professional tools, enabling single-person rapid wiring, docking and disassembly. The buckle locks firmly after docking with anti-loosening and anti-drop functions. It has strong anti-vibration and anti-pull performance, maintaining stable connection even in vibrating equipment and cable pulling working environments.
6. Wide Compatibility & Versatile Application
With standard M25 circular size, it is compatible with 0.5-6.0mm² cables. It is widely applicable to new energy equipment, outdoor lighting, engineering machinery, marine equipment, charging piles, industrial automation equipment, outdoor power supply systems and other high-power electrical connection scenarios.
7. Safe, Reliable & Cost-Effective
Integrated with waterproof, dustproof, shockproof, flame retardant and anti-corrosion performance, the connector adapts to harsh outdoor and industrial working conditions with stable performance and low failure rate. The standardized modular design ensures strong compatibility and easy replacement with zero maintenance, greatly reducing equipment operation and maintenance costs, serving as an ideal accessory for high-power outdoor and industrial electrical connections.

Frequently Asked Questions
Are your products certified? What certifications do you have?
All our products are certified by RoHS, CE, and other international standards. Specific certifications (e.g., FCC, UL) can be provided upon request based on your target market.
Can I have custom label?
Yes, of course, you can make your own private label and package. If you need to design the packaging, we also have professional designer to serve you.
What is rated Current?
Rated current, also known as operating current. With the rated voltage, as in the case below the rated current, air plug in general can work properly. Plug in the aviation design process, through the thermal design of the connector to meet the requirements of the rated current, because in contact with on a current flow out of date, due to conductor resistance and contact resistance, contact on will be heat. When the heat exceeds a certain limit, the plug will damage the insulation and the formation of air exposure on the surface of the coating to soften, resulting in failure.
