Interesting article.

Way back in time I used various sensors to detect the presence of glass vials and also whether they had an aluminium cap fitted. I recall that we experimented for some time with different mounting methods, recessed or flushed and also in a plastic material to get the desired range and field pattern.

At that time we were aware that we were affecting the field pattern, but manufacturers data or application notes were sadly lacking any details in those days and did not even mention that it could be an issue.

With perseverance we achieved what was required....

Thanks for the description.
