The GX Connector of Aviation Connector

What is a GX Aviation Connector?

The GX connector is a high-reliability circular connector featuring threaded connections and vibration resistance. Originally widely adopted in aerospace and military applications, it is commonly referred to as the “GX aviation connector” or “GX aviation plug.” The GX series represents a significant branch within this connector category, primarily used for power or signal transmission between electronic devices and instruments. It is particularly suited for operating environments involving frequent movement or vibration.

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.

GX Connector Flange Type Plugs

The difference lies mainly in the fact that the socket has a round, square, or diamond-shaped flange tray with holes in the tray, which are fixed with screws.

Accessories: waterproof cap

GX20 Flange: 2pin, 3pin, 4pin, 5pin, 6pin, 7pin, 8pin, 9pin, 10pin, 12pin, 14pin,15pin.	GX25 Flange: 2pin, 3pin, 4pin, 5pin, 6pin, 7pin, 8pin, 9pin, 10pin, 12pin, opening 25mm, female head black bakelite diameter 21mm.	DF30 GX30 M30 Flange: 2pin, 3pin, 4pin, 5pin, 6pin, 7pin, 8pin, 9pin, 10pin, 12pin, 14 pin connector, opening diameter (i.e. male diameter) 30mm, female black rubber diameter 25mm.

Note: DF Zhejiang Dengfeng GX series aviation plug, Dengfeng company did earlier, so some people also use DF name.

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.
