Outdoor 20A+5A Circular Connectors M25 2+20Pin IP67 Connectors Waterproof Factory China

The M25 2+20Pin hybrid circular waterproof connector combines 20A power and 5A signal transmission in a single IP67-rated outdoor connector. Featuring a self-locking structure, gold-plated contacts, and a high-performance PA66 shell, it is factory-direct from China and engineered for lighting, solar storage, surveillance, outdoor sensors, and robotic wiring applications.

This M25 2+20Pin hybrid circular waterproof connector is rated IP67 for outdoor use and built around a self-locking structure for quick, secure connection. Gold-plated contacts and a PA66 shell deliver reliable performance in demanding environments. Factory direct supply from China makes it suitable for lighting, solar storage, surveillance, outdoor sensors, and robot wiring.

The M25 hybrid circular waterproof connector adopts a 2+20 pin design for simultaneous power and signal transmission. Two high-current contacts are rated at 20A, while twenty signal contacts are rated at 5A. Power supply and control signals are integrated into one connector to simplify wiring.
The connector features a self-locking structure. Push to mate and lock quickly with one hand for easy assembly. Once locked, it is vibration-resistant and pull-proof, preventing accidental disconnection and greatly improving on-site wiring and maintenance efficiency.
With an IP67/IP68 ingress protection rating, the connector is fully dust-tight and resistant to temporary water immersion, making it suitable for outdoor, humid, dusty, and wide-temperature-fluctuation environments. The housing is made of high-performance PA66, and the gold-plated contacts provide low contact resistance, corrosion resistance, and a long service life.
Cable-to-cable and panel-mount versions are available. Custom pin assignment, cable assembly, color, and OEM/ODM service are supported. As a professional waterproof connector manufacturer in China, we offer stable lead times and factory-direct supply. Samples are available for testing.

Used between solar controllers, battery packs, and monitoring modules. The 20A 2-pin contacts transmit power, while the 20 signal pins collect voltage, current, temperature, and fault alarm data. Ideal for rooftop solar, farm solar, and remote power stations.
