Dear teams,

We are planning to use LDC1312 to make rectangular coils.

How to calculate the distance between the coil and the measurable distance?

Chu,

Depending on the coils' dimensions, you might be able to approximate rectangular coils as racetrack coils, which are supported by our Inductive Sensing Design Calculator Tool, which will also provide an estimate of the distance vs. inductance of the coil, along with other parameters.

The tool will also provide recommended device settings based on your design parameters.

Regards,
John

Hi John,

Thanks a lot.

May I ask another question.

What other factors are related to the induction distance of a coil besides its maximum diameter?

Chu,

The number of turns in the coil can also have a big impact on the inductance.
You can vary the diameter and number of turns in the Inductive Sensing Design Calculator Tool and look at the impact of the two parameters on the coil's inductance.

John
