5 common waterproof connectors

5 common waterproof connectors

waterproof connectors are widely used in environments that require waterproof, dustproof and corrosion-resistant, such as outdoor lighting, electrical control, automotive, marine and industrial equipment. Below are five common types of waterproof connectors and their differences and characteristics:

1. M12 waterproof connector

 M12 IP68 waterproof connector

Difference: belongs to M series round waterproof connector, diameter 12mm, commonly used in industrial automation, sensors and LED lighting.

Characteristics:

Adopt thread locking method, waterproof sealing ring to enhance the protection ability.

With shielding function, suitable for environments with high anti-interference requirements.

Supports different terminal configurations from 2-12 cores.

2. PG7 waterproof glands

PG7 IP68 waterproof glands

Difference: mainly used for cable fixing and sealing, suitable for different wire diameter cable access equipment.

Characteristics:

Made of nylon, corrosion and weather resistant.

Suitable for 3-6.5mm cable diameter, prevent water, dust and oil from entering the equipment.

Suitable for outdoor distribution cabinets, photovoltaic systems and LED lighting junction boxes.

3. RJ45 waterproof connector

Difference: designed for network cable connection, commonly used for outdoor network equipment, surveillance cameras and industrial communications.

Features:

With standard RJ45 interface, compatible with regular network cable.

With thread locking and rubber sealing ring to ensure stable data transmission.

Suitable for outdoor routers, Wi-Fi hotspots and other harsh environment applications.

4. MC4 Waterproof Connector

Difference: designed for solar PV system, suitable for electrical connection between PV modules.

Features:

Adopts high temperature and UV resistant material to ensure long-term outdoor use.

With self-locking function to ensure a solid connection and prevent accidental loosening.

Suitable for DC system, rated voltage above 1000V, current up to 30A.

5. M16 waterproof connector

Difference: suitable for industrial equipment, the shell is usually made of metal, with higher mechanical strength.

Characteristics:

Made of nickel-plated copper or stainless steel, impact resistance and corrosion resistance.

Suitable for 6-10mm cable diameter, widely used in automation equipment, robotic arms, aerospace and other fields.

With good electromagnetic shielding performance, suitable for environments with strong electromagnetic interference.
