Part Number: LDC0851

Hi Everyone,

I have been working on designing coils for LDC0851.

I tested a coil, with 6mm of diameter, 0.2mm of track width and 0.2mm of track spacing. The target is shown in image.

In my tests this coil work for small distance. My question is:

For increase the distance, between target and coil, to 5mm, I need increase or decrease the coil diameter?

Thanks !

Hi Matheus,

In general, increasing the diameter of your coil will increase its sensing range. However, making the coil larger than your target can decrease its sensitivity. You may need to experiment with different coil sizes to determine the optimal coil size for your target distance, size, and material.

Best Regards,
