Shielded cable between coil and PCB

[pepino]

Hello

I found this shielded cable, which looks ideal for my PI under construction (Surf 1.2). However, I have a question / this coil has only ONE wire inside, while the coil has two wires. Do I need 2 cables, or should I solder one coil wire to the cable shield and the other to the (one) wire of the cable ?

would you guys have some pictures of your own connections between the cable and the coil wires of your metal detectors to share with a beginner like me ?

Thks a ton

OK guys, forget my question, which was already answered to by one administrator (here is the text) :

Referring to the schematic, you can see that there are only two wires that go the coil. One is connected to the drain of the MOSFET, and the other is connected to GND (0V). Therefore you only need a single-core coax cable to connect this coil, as one of the connections is actually the braided shield of the cable. In your case, you appear to have used a 2-core coax, and are now wondering what to do with the shield. You can either disconnect the wire that is currently connected to 0V and connect the shield instead. Do this at both ends of the cable. Or simply parallel connect the shield with the wire that is connected to 0V. If your coil has a Faraday shield, you will also need to connect this to the cable shield.

i do not see your image.

Wow. Your sure trying to make this a lot harder then it is. Your surf only has two pads for the coil. Using Coaxial tie the Shield and one coil wire to the braided part of the cable. Braid goes to Ground on the PCB. Tie the remaining coil wire to the center conductor. That will connect to the other pad on the PCB. UUULA, Your Done.
