The GX Connector of Aviation Connector

CONTENT

Definition

Aviation plug socket connector, as the name suggests, refers to the connector components used in the aviation field, and is a general term for connectors in the industry.

There are countless connectors used for power transmission, signal transmission, etc. in the aviation field, and the product range is extremely wide. Therefore, the aviation plug socket does not refer to a model of the plug socket.

Different connector manufacturers that produce connectors for the aviation field are also different. For example, Amphenol AISG, Binder M12, M16, Weipu, etc.

Application Areas

GX series are suitable for electrical connection between instruments, electronic equipment, wires, and cables or through the wall partition connection, GX series threaded connection, stable electrical conductivity, and has a certain waterproof function.

Safe and reliable, it was first applied in the aviation field to meet the requirements of moving or vibrating environments. With the development of production technology and cost reduction, the civil field also began to be generally applicable.

Now it is widely used in aviation, navigation, computer, communication, petroleum survey, navigation, anti-theft device, transportation, mechanical electronics, and other fields.

Product Classification

GX series have different products according to the opening size. The common ones are GX12, GX16, GX20, GX25, GX30, GX35, GX40, etc. (The shape of the product is the same, only the size is different)

The number after GX represents the thread diameter size of the socket.
