Aviation connector for spindle: GX16, GX20 and 4 pin types
GX series aviation connectors are named by thread diameter: a GX16 connector suits small motors and signal lines, while a GX20 aviation connector carries more current for spindle power. The 4 pin aviation connector is the usual spindle plug. A waterproof aviation plug with a rubber seal helps on stone routers and water cooled spindles. The aviation socket is panel-mounted on the spindle body. Aviation connector price in India depends on size, pin count and sealing; as an aviation connector supplier in India we match the plug to your spindle.
Aviation Connector: frequently asked questions
Which aviation connector is used on a CNC spindle?
Most router spindles use a 4-pin aviation connector: three pins for the U, V and W phases and one for earth. Smaller spindles often use a GX16-size plug and larger ones a GX20 or bigger plug for higher current. ATC spindles may have an extra connector for sensors. Match the size and pin count to the socket on your spindle.
How do I wire a spindle aviation plug?
Use a shielded 4-core cable. Connect U, V and W from the VFD output to pins 1, 2 and 3, and earth to pin 4, following the spindle's pin diagram. Earth the cable shield at the VFD end. If the spindle turns the wrong way, swap any two phases at the VFD, not the earth.
