A miniature waterproof connector is suitable when the water from the environment can go inside your application and affect your product’s working operation. Therefore, applications like medical equipment, military, security, and communication industry, test and measurement applications, industrial applications, energy, and automotive industry.

Figure 2 – miniature waterproof connector

We see considerable development in medical, security, communication, and military equipment in the modern era.

Besides, more advanced testing instruments are coming into the scene. Furthermore, we can see massive development in the automotive industry also. Many of those applications are used outdoors. Even indoor applications have the possibility to get in touch with water.

Therefore, most applications of those industries need miniature waterproof connectors.

Figure 3 – IP rating

And when you are talking about miniature waterproof connectors, you are basically talking about the IP rating because that is the scale to measure how waterproof a connector is.

For better understanding, here we will discuss IP ratings definition.

The Basics of IP Rating

IP rating refers to Ingress protection which is established in the IEC 60529 standard. In that standard scale, the IP rating prefix consists of two numbers such as IP65, IP67, etc.

The first number in the IP rating represents protection against solid material, and the second number tells the protection against liquids. There are also regional or national equivalents for this standard, such as EN60529(Europe), ANSI60529 (America).

We prepared the following table to understand the number of IP ratings:

Dust and water enter easily to an exposed connector and damage the device. Therefore, determining the intended use of the application at the early stage is crucial. That’s how you will be able to select the proper IP rating for the miniature waterproof connector

You will see IP-rated miniature waterproof connectors in many applications. Devices with accurate IP ratings will protect the internal circuitry from any unwanted dust or water ingress when no external equipment or plug is connected.

On the other hand, in industrial connections, the IP rating should be higher. The purpose of miniature waterproof connectors is to make the connection fully sealed.

The sealed area must prevent moisture and dust from entering the circuitry and cause any disruption in the signal. Moreover, you need a miniature waterproof connector that prevents the device from continuous water flow for a long time.

You should know that a proper IP-rated miniature waterproof connector can not create an IP-rated connection alone. The design should include an IP-rated mechanism to produce a fully IP-rated connection. Though you need an IP-rated design, an IP-rated miniature waterproof connector is mandatory to make the design properly functional.

A push-pull miniature waterproof connector is highly secured. Therefore, you will see them in the most sophisticated applications, military departments, communication industry, and medical instruments.

Push-pull self-latching miniature waterproof connectors are used in various applications to transfer signals, data, currents, media etc., and you will need to establish a secure connection. For example, military vehicles contain much sophisticated electronic equipment, and they have to operate them in a harsh environment.

Moreover, they need to connect their pieces of equipment quickly to start an operation. Therefore, military departments need push-push miniature waterproof connectors in their communications, solder wearables, and instruments in the stations.

The medical industry is another space where you will see push-pull miniature waterproof connectors regularly. The medical department is a sector where doctors and nurses need to establish connections to the machinery quickly. Sometimes they need to quickly disconnect the connection to save the life of a patient. That’s why are in high demand in the medical industry.

Medical equipment needs some special care for both physical and technical reasons. Every medical equipment needs extensive sterilizations. That’s why metal-based push-push miniature waterproof connectors are mandatory for the medical industry.

Sometimes sterilization is not an option, and disposable or single-use connectors are used. You can easily manipulate a push-pull miniature waterproof connector, and they are available in IP67 and IP68 ratings. Those connectors are used in various medical devices, including intensive care and operating theatre.

In addition, flexibility is crucial in the medical industry. Here the medical staff needs to set up an operation or run a machine in quick time. Moreover, they need to plug out the connection very fast if any disaster happens. That’s another important reason why medical equipment needs quick connections, especially metal brass-made push-pull self-latching miniature waterproof connectors.

Every industry has its own set of requirements for miniature waterproof connectors. For example, connectors are used in the automotive that need to face high temperatures and vibrations. Therefore, if you look for a connector solution, you must follow the design specification.

INTE-AUTO connectors are used in medical, communication, military equipment, testing machines, automotive and industrial applications. We maintain the proper design specification for each of our connectors.

For example:

Figure 6 – Defense applications need the miniature waterproof connector

Miniature waterproof connectors for the military should confirm rigorous safety standards for the associated institutions. They should come with an increased impact and shock rating.

On the other hand, the connectors are shell-type and must possess the design specification focused on military operations. The military-grade miniature waterproof connectors must be able to protect themselves from environmental factors. Those connectors need to follow the design specifications for military applications and aerospace.

Miniature waterproof connectors are used in various applications. You will see them in households, commercial, security, testing multiple applications. For instance, outdoor lighting, outdoor signage, outdoor communication system, outdoor security system, etc.

Furthermore, miniature waterproof connectors are used in the retail industry, Defense and aerospace, automotive, medical, and industrial products industries. And none of these and the above sectors are not demolishing soon, nor are they switching their application type and working process.
