UL Listed Waterproof Wire Connector
Product Description
Product Detail
HuaYi-FaDa UL Listed Waterproof Wire Connector is designed for sealed cable connections in LED lighting and automation equipment where the connection needs to remain protected in outdoor or moisture-exposed installations.
Advantages
Wider Cable and Electrical Range
The SK19 configuration covers 14–20AWG cables with a 4.0–12.0 mm cable diameter range. Its 7–15A rated current and 600V AC RMS operating voltage provide a higher electrical range for compatible lighting and electrical assemblies.
The molded-cable structure integrates the connector and cable into one assembly. Cable length and cable type can be customized to suit different wiring layouts, reducing the need to separately arrange the cable connection at the connector side.
Gold-Plated Contact Interface
The contact pins are made from copper alloy with nickel plating. The specified contact resistance is below 5 mΩ, while insulation resistance exceeds 500 MΩ. The connector is rated for at least 3,000 mating and unmating cycles.
IP68 Sealing Structure
The SK19 uses a silicone seal and an engineering-plastic housing to form its sealed connection structure. The IP68 rating supports applications exposed to dust and water immersion. The supplied product information also specifies resistance to many oils and chemicals.
Corrosion-Resistant Plastic Nut
The black connector shell is available with a black or grey plastic connection nut. The plastic construction provides corrosion resistance for connection assemblies used in outdoor environments and areas exposed to moisture or salt.

Cable Customization for Different Assemblies
The SK19 is supplied as a molded-cable connector, with cable type and cable length available for customization. This configuration is suited to lighting fixtures and electrical equipment where the cable needs to be integrated directly into the connector assembly.
Available Connection Combinations
A cable-free solder connector is also available within the same connector range. It can be matched with the molded-cable version in compatible lighting fixture designs.
This provides two connection formats:
-
SK19 molded-cable version for integrated cable assemblies
-
Cable-free solder version for solder termination
-
2-pin / 3-pin / 4-pin configurations
-
14–20AWG cable selection
-
4.0–12.0 mm cable diameter range
-
Customized cable type and cable length
Lighting and Automation Applications
-
LED Lighting
The connector is used for LED strips, LED wall washers, LED underground lights, LED rope lights, LED belt lights, curtain lights, and twinkle lights. The molded cable format integrates directly into the wiring structure of the lighting assembly. Browse waterproof LED connectors.
-
Automation Components
The stated applications include proximity switches, flow-monitoring devices, fieldbus components, sensors, and actuators. The IP68-rated structure provides a sealed connection format for compatible automation equipment. View waterproof circular connectors.
-
Outdoor Electrical Equipment
The connector's IP68 protection, corrosion-resistant plastic nut, and -40°C to +105°C temperature rating make it suitable for compatible outdoor electrical assemblies exposed to moisture, dust, and environmental conditions.
Certification and Quality Control
The SK19 is listed with UL, CE, and RoHS certification. Its IP68 protection rating and UL94-V0 flame-resistance specification are also stated for the product.
HuaYi-FaDa's quality system includes 100% inspection before delivery, with the company reporting that products undergo testing and inspection rather than relying solely on batch sampling. The manufacturer has supplied OEM products to Amphenol, Philips (Signify), and OSRAM for more than seven years. See company information.
Project Supply
The SK19 is available for customized cable assemblies, with cable type and cable length selected according to the required wiring arrangement. OEM and ODM support is available for connector projects requiring customized designs or tooling.
Three free samples are available per part number for a one-time request, excluding shipping charges. The stated production lead time is two to three weeks after order confirmation.
Request the HuaYi-FaDa UL Listed Waterproof Wire Connector for SK19 2-pin, 3-pin, or 4-pin configurations, customized cable assemblies, and compatible solder-type connection requirements.
FAQ
How do I choose between 2-pin, 3-pin, and 4-pin SK19?
Match the pin count to the number of conductors in the circuit. Use 2-pin for simple power or signal pairs, 3-pin with ground or an extra signal, and 4-pin for additional conductors.
Can the SK19 molded-cable version be assembled in the field?
No. The molded-cable version is factory-assembled with the cable integrated into the connector. For field termination, use the cable-free solder version.
What cable types and lengths can be customized?
Cable type and length are customizable for the molded-cable version. Provide the required length, jacket material, conductor size, and core count to confirm the assembly.
How should the SK19 be maintained to preserve IP68 sealing?
Inspect the silicone seal and housing for damage, keep the mating surfaces clean, and fully engage the connection. Replace any damaged seal or connector part before reuse.
Does the plastic nut color affect performance or corrosion resistance?
No. Black and grey nuts use the same plastic construction and corrosion-resistant properties. The color choice is for appearance or equipment matching only.
For the UL Listed Waterproof Wire Connector, confirm pin configuration, cable type and length, wire gauge, and required quantity before production.
