Waterproof Plug and Socket Connector

Waterproof plug and socket connectors are ideal for industrial applications in marine, automotive, and outdoor settings. They help ensure electrical connections remain secure in harsh environments, avoiding the risk of costly disruptions and repairs.

These connectors form extremely tight seals to resist high moisture conditions, such as saltwater vapor, rain, and snow. They can also protect against damage caused by chemicals.

Ingress Protection (IP) Ratings

In electrical equipment, the ingress of solid particles or water can cause damage or failure. To protect your electronics, you should choose equipment that has been properly tested and is rated to be waterproof. This is often indicated by an IP rating or ‘code,’ which identifies the device’s ability to resist ingress.

Depending on your needs, different ratings can protect against varying levels of water ingress or dust ingress. IP ratings are categorized by two digits, with the first waterproof plug and socket connector number indicating how well the device is protected against solid foreign objects and the second number indicating how well it is protected against liquids. For example, a device with an IP67 rating can be fully submerged in water for up to 30 minutes without experiencing harmful levels of ingress.

The specific insulating materials used in the construction of your connectors will also play an important role in their ability to repel dust and water. The shape of the connector housing and thread pattern or mating mechanism are other factors that can contribute to its ability to provide reliable protection. For example, circular connectors are easier to connect and disconnect and are less likely to break if they’re subjected to mechanical shock. Choosing a high-quality plastic composite that is resistant to corrosion and extreme temperatures can also increase the lifespan of your connectors.


Electrical components that operate in wet environments require waterproof connectors to create a solid connection and prevent damage to wiring or circuitry. Waterproof connectors are specially designed to ensure that they can withstand harsh environmental conditions, including exposure to moisture, dust and dirt. This is important because these factors can disrupt critical signals or cause corrosion.

Waterproof plug and socket connectors are used in a wide variety of applications, including industrial and marine electronics, datacom/telecom infrastructure, construction equipment, lighting and stage lighting equipment, off-road vehicles, traffic control systems and power/energy installations. They are also used in a number of medical devices, as well as electronic appliances such as kitchen equipment and televisions.

In addition to the waterproofing features of these connectors, they typically offer a range of other advantages. For example, they may be designed to withstand extreme temperatures (high or low), or they may be made from materials that resist corrosive elements. They may also be able to withstand the pressure of pressurized jets of water.

Moreover, waterproof plug and socket connectors are easy to use and can be easily integrated into a wiring harness without damaging the wire insulation. This means that they can reduce the time and effort required for wiring harness production, as well as the inventory and storage management pressures associated with these components.


Whether in marine wiring, industrial equipment, or power cable layouts for LED lighting, indoor plant power traction, or outdoor garden lamp wiring, waterproof plug and socket connectors ensure the safety of connections. These connectors are made of plastic, metal and aviation to provide waterproof connector manufacturer maximum protection from water, dust, dirt and chemicals in harsh environments.

For a wide range of demanding applications, Fischer Connectors offers waterproof plug and socket connectors with a variety of shell sizes, contact styles, wire gauges and mating cycle ratings to support different uses in harsh environmental conditions. Featuring a variety of mounting options and cable seals, these connectors also feature user-friendly features like one-touch push-and-twist locking mechanisms to help speed up connection times.

Waterproof connectors typically use interface O-rings to create a static seal, but the environment in which they operate may still expose the O-rings to moisture and other contaminants. O-ring material selection is critical to maintaining waterproof performance. For instance, EPDM (ethylene propylene rubber) elastomer has high water resistance and low glass transition temperature that makes it a preferred choice for the interface O-ring of waterproof connectors that are frequently mated and unmated.

Newark, An Avnet Company stocks eco|mate Aquarius waterproof connectors from Amphenol Sine Systems, including a wide variety of shell sizes, contacts, wire gauges and mating cycles. These rugged waterproof electrical connectors offer a flexible solution to reduce system complexity and installation costs in a wide range of industrial applications such as automation and control, stage lighting, power and energy, off-road vehicles and mining equipment.


Waterproof plug and socket connectors create a tight seal between two electrical components, preventing moisture from damaging the circuit. They’re suitable for use in a wide variety of applications, including marine, automotive, and industrial equipment. When choosing a waterproof connector, it’s important to consider its IP rating and the environment in which it will be used. IP ratings indicate how well a connector is protected against liquids, dust, and other environmental elements. A higher IP rating indicates a greater degree of protection.

To install a waterproof electrical connector, you’ll need to first attach it to the surface on which it will be mounted. The bottom part of the connector comes with a rubber sealing gasket to ensure that it stays in place. The top part of the connector features a securing screw ring that mechanically holds the two parts together. It’s important to select a screw or nut that’s large enough to fit through the connector’s mounting holes.

Waterproof connectors are designed to withstand harsh environments and high-demand applications. By protecting connections from moisture and other environmental factors, they reduce the risk of costly downtime and disruptions. They also help ensure a safe, reliable, and durable connection, delivering unparalleled performance in demanding conditions.
