Latest company news about This section describes the M8 waterproof connector

The M8 connectors are now recommended for almost all bus specifications used in the field. They comply with the IP67 protection level according to the IEC61076-2-101/104 standard and are traditionally used to connect sensors&actuators in automation technology.D-coded 4 pin connectors for Industrial Ethernet applications have a higher level of protection.

The main function of the M8 connector is to design with stable connection in harsh environments. Compared with other types of connectors, it has the advantage of being tougher and more resistant. The connector of this new interface is called "industrial connector",which scope of use is not single, not only being used in manufacturing, but also in many other fields.

Basic performances of M8 connector:

The basic performance of M8 connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance.


(1) Mechanical properties

Functionally, the most important thing is the mechanical properties of the connector. The insertion force is divided into the insertion and the extraction force (the extraction force is also called the separation force), and the requirements of the two are also different. The key criteria are the maximum insertion force and the minimum separation force. From a usage point of view, the insertion force should be small (thus there is a structure with low insertion force LIF and no insertion force ZIF), and if the separation force is too small, it will affect the Contact reliability. The mechanical life is actually a kind of durability index, which we usually call it mechanical operation in the world. It takes one insertion and one extraction as a cycle, and judges whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and extraction cycle.


(2) Electrical properties

As we all know, the main electrical properties of connectors include contact resistance, insulation resistance and electric strength.


(3) Environmental performance

The environmental performance is actually a general term including temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance.

Features of M8 connector

1. Waterproof, moisture-proof, rain-proof, sun-proof and anti-corrosion.

2. Flame retardant, anti-oxidation and environmental protection (all products are from green production lines).

3. Improve the production process: The connector simplifies the assembly process of electronic products and the mass production process.

4. Easy to maintain: In the event of a failure, there is no need to break the cables, electric plastic sleeves, etc., only need to unscrew the two ends of the waterproof connector, which is very convenient for the maintenance of waterproof products such as LED, solar energy, geothermal, etc.

5. Improve design flexibility: Using connectors gives engineers greater flexibility when designing and integrating new products, as well as when using components to form systems

Application areas of M8 connectors

All products are made of environmentally friendly and high temperature resistant materials, which meet the ROHS standard, and can provide formal environmental protection materials.The product appearance is brightly plated by real photographed and there is no adulteration.


1. Widely suitable for outdoor application connection of various LED products, such as LED strips, LED spot lighting, LED wall washer landscape lighting, LED billboard lighting, LED tunnel lighting, LED flood lighting, LED street lighting and LED outdoor display screen etc.


2. Widely used in coastal, river, lake or underwater engineering, mining engineering, underground engineering, solar water heater, solar wind power generation, food industry, various mechanical equipment, aviation, aerospace, national defense and other communication & power supply fields.
