Product Details

Super Thin Enameled Copper Winding Wire For Watch Coils

 

In speakers, ultra-thin enameled copper wires can be used to make coils, which are usually used for sound amplification and driving of speakers.

 

The main application of ultra-thin enameled copper wire in watch coils is to make electromagnetic induction coils. These coils are often used in automatic or quartz movements of watches to control the oscillation frequency of the quartz crystal or to drive a motor.

 

Since watch movements often require very small dimensions, ultra-thin enameled copper wire is particularly important because it can be easily wound into coils and fit into limited spaces.

 

This kind of coil needs to have stable electrical characteristics and precise coil parameters to ensure the performance and accuracy of the movement.

 

Therefore, ultra-thin enameled copper wire is widely used in watch manufacturing to make coils, which contributes to the precise performance and stable operation of the watch movement.
