Sensor required to detect PVC insulated COPPER wire

please see picture, the wire lies under Fibre glass mesh, When the mesh moves I have to count no.off copper wire loops. Please suggest suitable sensor.

If the mesh moves at constant speed, How about a simple optical IR Sensor (break beam or Reflective), then checking pulse width of signal to detect mesh vs cable. Otherwise synchronize pulse width detection ratio in correlation to mesh speed.
Similar to this

Or create a metal detector, that will detect every copper wire that passes below the sensor.
What is important is to ensure a good reliability, so you are getting results that is reliable. Both IR detector and metal detector should be usable for you

Try inductive proximity sensor. It can detect Cooper with 0.25 - 0.5 sensitivity compared to steel. By the way I think we can see one of this on top side of your picture.

If the copper loop is continuous (it looks like it is), inject a small RF (mW) signal on the wire (at the feed end of the mesh) and place the complement detector under the final end.

@mrrobots Thanks for the reply. I don't have much knowledge about injecting RF signal. Please give me more inputs.
