Waterproof Plug and Socket Connector

Waterproof plug and socket connectors protect electrical connections from moisture, which can corrode wires and create shorts. They are used in a variety of industries, including marine wiring and outdoor lighting.

They join electrical devices in wet environments, such as humidity and rain, by forming an extremely tight seal. They can also resist high current applications.


Waterproof plug and socket connectors are designed to protect electrical connections from the damaging effects of moisture. They feature rubber or silicone seals that fit tightly around wires or cables, ensuring a secure and watertight connection. Many also have latches or locks that help to prevent accidental disconnections. These durable, versatile connectors can be used in a variety of harsh environments, including industrial, commercial, and residential settings.

Waterproof connectors can be rated by their Ingress Protection (IP) rating, which determines how well they will perform in wet and dusty conditions. The first number in the IP rating identifies how well the connector resists solids like dust, and the second number indicates how well it can be submerged. The higher the number, the more protection the connector offers.

Choosing the right waterproof connector for your application can be challenging. You must consider the current ratings of your equipment, as well as the temperature range where you will be using it. Choosing a waterproof connector that is rated for your specific application will ensure your equipment remains safe and functional in the most challenging environment. PEI-Genesis specializes in custom assembling waterproof connectors from components, so you can be sure that your new connector will meet the specifications of your application. We have a massive inventory of waterproof connectors and are available to assist you with finding the perfect fit for your needs.

Ingress Protection (IP) Ratings

Harsh environments can throw a variety of stressors at electrical connectors, which must be sealed tightly to keep debris and fluids from disrupting signals or damaging critical components. The IP (ingress protection) ratings of plugs and sockets provide useful information about how well a device will protect against these hazards, but there are many design considerations that can influence the final IP rating of a connection.

The IP system uses a standardized scale with waterproof plug and socket connector two numerals to indicate how resistant the product is to solid object and liquid ingress. The first number refers to the level of dust and particle resistance, while the second number indicates the level of water resistance. The highest IP ratings promise complete dust and water protection.

A typical IP67 rating, for example, means that the connector is completely dust-tight and can be immersed in one meter of water without becoming unsafe. It also demonstrates that the connector can resist powerful water jets from any direction.

A wide range of industrial connectors with different IP ratings are available, each designed to meet a specific application. Engineers should carefully review the IP ratings of each component to ensure they are waterproof electrical box connectors choosing the right one for their project. If they are unsure, they can ask the experts at Northern Connectors for guidance before placing an order.


Many industrial environments require electrical connectors to function in extreme conditions. This can include exposure to humidity, rain and snow, salt water, or pressurised water for cleaning purposes. These harsh environments create increased risks of moisture ingress, which can cause serious problems and damage equipment. To protect the connections from moisture, engineers can choose to use waterproof plug and socket connectors. These waterproof circular connectors create a tight seal around the connection point, protecting it from any ingress of moisture.

Waterproof connectors allow for easy installation and mating, while also preventing moisture and debris from disrupting or damaging the connection. This helps to prevent electrical signals from being interrupted or disrupted, which reduces the risk of electrical failures and accidents. Waterproof connectors are available in a variety of pin configurations, power ratings, and dimensions to accommodate different applications. They also feature built-in locking mechanisms for easy installation and removal, which saves time and effort during maintenance and assembly.

In addition to enhancing safety, waterproof plug and socket connectors provide additional benefits that make them indispensable in challenging environmental conditions. These include reducing the risk of corrosion and extending the lifespan of connected devices. In addition, they are made of environmentally friendly engineering materials that reduce the impact on the environment. These materials are also flame retardant and have a low flammability rating.


Waterproof connector cables are designed to protect electrical wiring harnesses from moisture in wet, damp, or underwater environments. They offer many benefits, including durability and ease of use, making them an important component in a wide range of applications and industries. They can be used in marine wiring, outdoor lighting, and industrial equipment. Waterproof connector cables are available in a variety of shapes, sizes, and current ratings. The most common waterproof connector is the sealed connector, which has a plastic or rubber seal that prevents water from entering the wire contacts.

Watertight connectors provide long-term durability and reduce maintenance costs. They can withstand heavy rains, extreme temperatures, and harsh chemicals, helping to keep your devices safe and operational. They also help to prevent damage from dust and other environmental factors, which can corrode connections and cause costly malfunctions.

To make sure you choose the right waterproof connector, it is important to select one that has a high IP (Ingress Protection) rating. The IP rating determines how well the connector can withstand different operating conditions, including submergibility, resistance to dust, and protection from high-pressure water flow. It is also important to match the size of the connector hole, wire insulation, and the sealing plug or blind plug. If they are not closely matched, liquid could seep into the connector and disrupt critical signals.
