I was wondering if an industrial-grade inductive sensor can detect an anodized aluminum plate. From what I know, based on the working principle of these sensors (basically the metal is detected by its own magnetic field thanks to Eddy current) I suppose the sensor would have a hard time detecting the anodized surface, but I'm not sure.
Kindly let me know based on your experience or knowledge regarding the topic. Thanks in advance!
P.D.: In case you ask about the specific type of anodizing, for this case let us consider a simple Type-II anodizing, with a thickness no greater than 0.4 mils.
