Waterproof Plug and Socket Connector

Waterproof plug connectors are essential for marine and outdoor technology as well as other electrical equipment in harsh environments. Without the proper waterproofing, moisture can disrupt critical signals and corrode contacts.

When assembling wiring harnesses, the gap size between the waterproof plug and the wire insulation is important. This relationship impacts the quality of the overall integration.


Waterproof plug connectors are electrical components that protect wire connections from moisture, water, and other environmental factors. These features help ensure that connections continue to function properly and reduce the risk of downtime due to failure. In addition, waterproof connectors can withstand a range of temperatures and resist corrosion.

Connectors are essential components that enable the smooth flow of power, signals, and data between devices. They play a crucial role in many industries, including marine, automotive, industrial, and outdoor settings. However, when it comes to connecting electronics in these environments, the quality of the connection can make or break the system. This is especially true of waterproof plug and socket connectors, which are designed to provide a reliable and robust solution for all weather conditions.

These connectors feature rubber or silicone seals that fit tightly around cables and wires, ensuring a secure and watertight connection. They also have additional locking mechanisms to prevent accidental disconnections. These waterproof connectors are ideal for marine, solar, and automotive applications, as well as for outdoor lighting, surveillance cameras, and renewable energy installations.

Ingress Protection (IP) Ratings

Waterproof plug connectors are designed to resist a variety of environmental hazards, such as dust and liquids. They form tight seals that protect electrical connections from the intrusion of contaminants, which waterproof plug and socket connector can disrupt critical signals and corrode contacts. They are an ideal choice for marine, outdoor, or any indoor environment that is exposed to high moisture.

In the electronics industry, a product’s IP rating is one of the most important factors to consider when selecting an enclosure. The IP rating system is comprised of two numbers that represent the level of protection against solid objects and liquids. The first number refers to the protection against solid objects such as dirt, sand and dust while the second number refers to the protection against liquids like water and moisture.

The numbers in an IP rating range from 0 to 8, with the higher ratings providing more protection. For example, a product with an IP68 rating can be submerged in water for up to 1 hour. PEI-Genesis offers a variety of waterproof plug and socket connectors to meet your specifications, including rugged push-pull IP68 connectors with panel hole cutout sizes up to 13 mm and the Cliffcon 68 front-mount male connector that is available with 2 to 9 gold-plated contacts in a high-density arrangement.

When purchasing waterproof connectors, make sure to also consider the current rating, which is the maximum amount of electrical current that a connector can handle without overheating or causing a fire. You can find the current rating on the packaging or listed in the product specifications.


Connectors are an integral part of many electrical systems, serving as vital components that ensure seamless flow of power and signals. However, many electronic devices are exposed to challenging environments that can damage or corrode connectors over time. Waterproof plug and socket connectors are designed to withstand moisture and other environmental factors, protecting their wiring and preventing electrical malfunction. This significantly enhances safety by eliminating potential electrical shock hazards and prolonging the lifespan of equipment.

UL waterproof plug connectors use rubber gaskets or silicone seals to create a tight barrier against water ingress. They also feature specialized locking mechanisms that ensure a secure connection that can withstand vibrations and pull forces. Some models are even submersible in water, ensuring they can safely operate in wet conditions.

In addition, waterproof connectors are made from materials that meet stringent flammability standards, providing added protection against fire hazards. Some models have a flame class of UL94, which indicates that they are self-extinguishing waterproof electrical box connectors and will not propagate an ongoing fire after the initial contact with a flame.

In addition, most UL waterproof plug and socket connectors have a cord side exit that is more convenient for appliances with molded cords. This design is more safe because it eliminates the risks associated with unplugging appliances by grabbing the cord top, which could cause an electric shock.


Waterproof connectors create a seal that protects electronic or electrical devices from moisture. They can be used in damp environments and some can even be submerged underwater. They are commonly used in marine, automotive, and industrial applications and in equipment that must be safe from electrical hazards.

Water-resistant connectors are typically made from materials that can withstand the harshest conditions. They are also designed to provide strain relief and prevent cable pull-out forces from damaging the connection. Additionally, they can withstand vibration that may affect the connection.

The waterproof connectors we carry at Newark are available in a wide variety of shell sizes, contact styles, wire gauges, and power and signal insert layouts. They are able to reduce system complexity and installation costs in harsh-environment applications that require durable and reliable connections. These include marine electronics, datacom/telecom infrastructure, traffic control systems, building automation and control, off-road and railway vehicles, mining equipment, and stage lighting and sound equipment. They are available in a variety of IP ratings and features, including quick and reliable bayonet coupling with tactile mating confirmation, IP68/69k protection when mated, and corrosion resistance. These features make them ideal for marine, automotive, industrial, and outdoor applications. They are also an excellent choice for equipment that requires sterilization and moisture resistance, such as medical instruments.
