Yes I've seen something like this and i have a few examples. But mine has been made into a finished product, mounted in the threaded housing and sealed up with plastic and a cable with a connector on it. They work well and are reliable. They are repeatable if the 0.001 inch level. I bought mine for measuring there flatness of a 3D printer build platform. The idea is to scan the sensor over the platform am measure the distance in a grid pattern. The sensor works for this purpose and could make a good home sensors too.
You can buy them on ebay for a few bucks. ebay.com/itm/LJC18A3-B-Z-BY-PNP-NO-3-Wires-10mm-Capacitive-Proximity-Sensor-Switch <https://www.ebay.com/itm/LJC18A3-B-Z-BY-PNP-NO-3-Wires-10mm-Capacitive-Proximity-Sensor-Switch-DC-6-36V-/161701766400> These are easier to use than the bare IC chip On Sat, Oct 6, 2018 at 7:01 AM Kenneth Lerman <[email protected]> wrote: > Kenneth Lerman <[email protected]> > Thu, Oct 4, 7:54 PM (2 days ago) > to Emc-users > ...for less than three dollars... > <https://www.idt.com/document/dst/zmid520x-datasheet> > > I don't know what I might use it for, but it seems pretty neat. > > Ken > > Kenneth Lerman > 55 Main Street > Newtown, CT 06470 > > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users > -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
