Product Description

The M19 Waterproof Male and Female Screw Connector is a universal waterproof connector independently developed and manufactured by HuaYi-FaDa Technology. Its core function is to achieve reliable circuit connection and environmental sealing protection, suitable for various scenarios requiring waterproofing and dustproofing. We employ standardized production processes to ensure the dimensional accuracy and performance consistency of each M19 Waterproof Male and Female Screw Connector. We can provide 2-pin, 3-pin, and 4-pin pin specifications according to customer needs to meet the actual needs of different circuit connections.

This product uses a screw terminal wiring method, eliminating the need for complex tools to complete wire connections, significantly improving installation efficiency and reducing wiring error rates. The M19 Waterproof Male and Female Screw Connector features a new nylon housing with excellent wear resistance, high and low temperature resistance, and corrosion resistance, making it suitable for harsh industrial and outdoor environments. Nickel-plated copper alloy contacts effectively ensure stable conductivity, reduce contact resistance, and prevent equipment failure due to poor contact.

Core Product Features


  • Reliable Waterproof and Dustproof: The product achieves an IP68 waterproof rating, allowing immersion in 1 meter of clean water for 4 hours without leakage. It is also completely dustproof, effectively preventing dust and moisture from entering the internal components, protecting circuit safety, and is suitable for various applications such as outdoor lighting and new energy sources.
  • Multiple Specifications Compatible: Standard configurations include 2-core, 3-core, and 4-core options. Customization with more cores is available upon request. Wiring supports screw terminal connections for easy operation and compatibility with different wire specifications, offering strong versatility.
  • Durable Material Selection: The outer shell is made of new nylon material, V-0 flame retardant, with a temperature range of -25℃ to 105℃ and high mechanical strength; the contacts are made of nickel-plated copper alloy, ensuring stable conductivity, oxidation resistance, and corrosion resistance, extending product lifespan.
  • Easy and Efficient Installation: Utilizing a threaded male-female connector design, it allows for smooth insertion and removal, and a secure lock. No professional installation experience is required; assembly and disassembly can be completed quickly, facilitating future equipment maintenance and repair.
  • Strict Quality Control: Every M19 Waterproof Male-Female Screw Connector undergoes 100% full inspection, not batch sampling, covering key indicators such as contact resistance, insulation resistance, and waterproof performance to ensure product performance meets standards.


Product Technical Advantages


1. Sealing Technology Advantages

We employ a multi-layer sealing structure design, combined with high-quality silicone waterproof rings and epoxy resin potting process, effectively improving the product's sealing performance. This resists the effects of rain, humidity, dust, and other environmental factors, ensuring reliable connections in complex environments. The sealing structure has undergone repeated testing and can withstand long-term insertion and removal as well as environmental corrosion, resisting aging and deformation, ensuring long-term stable operation of the product.


2. Optimized Conductivity

The contacts of the M19 Waterproof Male and Female Screw Connector are made of high-purity copper alloy with a nickel-plated surface. This not only reduces contact resistance (≤10mΩ) but also improves oxidation and corrosion resistance, avoiding problems such as poor conductivity and overheating caused by contact oxidation. Simultaneously, the screw terminal design ensures a secure wire connection, reducing loose contacts and guaranteeing the stability and safety of circuit transmission.


3. Structural Design Advantages

The product features a compact threaded structure design, resulting in a small size and minimal installation space required, adaptable to the installation needs of various equipment. The shell is manufactured using a one-piece injection molding process, eliminating seams and further enhancing waterproof performance and mechanical strength. The male and female plugs are highly compatible; products of the same model and specification can be fully mated and disassembled, facilitating mass assembly and replacement.


4. Environmental Adaptability Advantages

The M19 Waterproof Male and Female Screw Connector can operate within a temperature range of -25℃ to 105℃, with a storage temperature range of -25℃ to 85℃. It can operate normally in environments with atmospheric pressure of 86–106 kPa and relative humidity ≤90%. After salt spray testing (5% sodium chloride solution, 35±2℃, 48 hours), the product showed no significant corrosion, making it suitable for corrosive environments such as coastal areas and chemical plants, with a wide range of applications.
