15A+5A M19 3+4 Pin IP67 Connectors 300V Waterproof Power Signal Wire Connector

1. Split Pin Layout with Dual Independent Current Circuits
Designed with separated 3+4 pin structure for independent power and signal transmission: 3 pins support 15A high-current power supply, 4 pins for 5A low-current signal transmission. Physical isolation between strong and weak current eliminates signal noise and current interference effectively.
Rated voltage up to 300V, dual circuits work simultaneously without mutual influence. It integrates high-power power supply and multi-channel control signals in one connector to simplify wiring harness layout.
Optimized current-carrying design for high-current pins controls temperature rise under full-load long-term operation, avoiding overheating and short-circuit risks.

2. IP67 Full Sealing for All-Weather Waterproof & Dustproof Performance
Equipped with integrated elastic sealing ring and compression sealing structure, reaching IP67 protection rating. It fully blocks rainwater, mud, condensed moisture and industrial dust from contacting internal terminals.
Aging-resistant sealing parts retain stable sealing capacity after frequent plugging, suitable for open-air equipment, humid workshops and spray working environments.
Internal waterproof insulation prevents electric leakage and signal interruption caused by dampness, ensuring consistent equipment operation.

3. Reliable Conductive System for Long Continuous Operation
Thickened conductive base on high-current pins supports stable 15A load without performance loss; refined signal pins feature ultra-low impedance to guarantee lossless data transmission under 5A weak current.
Corrosion and oxidation resistant contacts avoid poor contact or power failure after long-term service outdoors or in industrial environments, cutting equipment maintenance costs.
Housing meets 300V insulation standard with thickened insulation layers between power and signal pins to prevent cross-circuit hazards.

4. Universal Circular Wire Connector for Easy Assembly
Standard M19 circular wire-to-wire design without PCB mounting requirement, enabling fast harness assembly and matching mass production assembly lines.
Built-in anti-loosening limit buckle keeps tight connection after docking, resisting loose-off caused by equipment vibration and slight pulling force.
Compact and lightweight structure saves wiring space, ideal for external wiring of small and medium intelligent devices.

5. Wide Application Range
Outdoor photovoltaic accessories, landscape lighting, outdoor surveillance power & signal wiring;
Small industrial automation equipment, sensor controllers and portable outdoor electrical devices;
All 300V low-voltage equipment requiring integrated high-power supply and multi-channel weak signals with waterproof and dustproof demands.
