Quick Release Wire Connector M19 3+9 Pin OEM Waterproof 300V Connector
Quick Details of 5Pin waterproof connector
-
Core Configuration & Customization Advantages: The M19 3+9 Pin Quick-Disconnect OEM Waterproof Connector is an industrial-grade wire connector that supports customization. It features a separate structure of 3-pin main power and 9-pin data signal, with a rated voltage of 300V. Combined with IP67 waterproof performance and a convenient quick-disconnect mechanism, it is specifically designed for scenarios requiring efficient plugging and unplugging as well as personalized needs. Serving as an OEM-exclusive solution, it can flexibly adapt to various equipment interfaces, achieving the dual objectives of stable power supply and accurate multi-channel data transmission.
-
Push-Type Quick-Disconnect & Double-Buckle Fixing: It innovatively adopts a push-type quick-disconnect structure, enabling unlocking and separation of the connector without tools. Compared with traditional threaded connections, the plugging efficiency is increased by 70%. In the locked state, it is secured by double buckles, which can effectively prevent accidental disconnection during equipment operation or transportation, balancing convenience and stability.
-
Dual-Function Pin Arrangement: The connector is equipped with a dedicated 2-pin power zone for efficient 300V power supply, along with a 20-pin data zone that enables high-speed, low-interference signal transmission. This separated structure avoids cross-interference between power and data circuits, guaranteeing stable energy supply and accurate data transfer in complex systems.
-
IP67 Waterproof & Dustproof Capability: Fitted with precision sealing gaskets and a robust M19 housing, the connector achieves IP67 protection rating. It can effectively resist rain, splashing water and dust accumulation, delivering reliable performance in outdoor, industrial or damp environments such as factory workshops, outdoor equipment stations and marine applications.
-
Push-Lock Mating System: Features a user-friendly push-lock mating mechanism that allows tool-free one-handed operation—simply push the male and female connectors together until a "click" sound confirms secure locking. This design not only reduces installation time by 40% compared to threaded connectors but also prevents accidental disconnection due to vibration, impact or external pulling.
-
Industrial-Grade Stability & Durability: Power pins are constructed from high-conductivity copper alloy with silver plating, capable of efficiently handling 300V loads. Data pins adopt gold-plated copper alloy to minimize contact resistance and ensure error-free signal transmission, combining excellent stability and durability.
