DocScrutinizer05hi folks! a question: I got a sensor consisting of a coil with a permanent magnet core that creates pulses when a iron tab approaches or goes away from the core.11:40
DocScrutinizer05how much external magnetism would I need to saturate that design completely so it doesn't work anymore?11:41
DocScrutinizer05or is it possible at all to saturate such sensor?11:46
DocScrutinizer05maybe I should try a way too high frequency external alternating magnetic field, so the signal drowns in noise?11:47
Action: DocScrutinizer05 idly wonders what's the noise immunity of the circuit consuming the signal from this sensor anyway11:48
DocScrutinizer05maybe the idea to just introduce some iron dust into the system, to clog the sensor with it, is the better idea ;-)11:49
DocScrutinizer05however I'm afraid even that won't work in the end11:50
DocScrutinizer05prolly time to apply some field change order to the electronic circuit after the sensor ;-D11:51
DocScrutinizer05hmmm :-))  https://www.conrad.de/de/reed-kontakt-1-wechsler-175-vdc-025-a-5-w-glaskolbenlaenge1473-mm-hamlin-mdrr-dt-503642.html12:00
DocScrutinizer05integrating this thing into a usual car electric connector and hiding it under some shrinktube shouldn't be difficult and look pretty normal12:03
DocScrutinizer05any other nearby component could create a magnetic field when needed12:04
DocScrutinizer05for an interim solution a permanent magnet hidden somewhere - and removed just in case, to revert to original function - should do, eh?12:05

DocScrutinizer05hmm 30 AmpereTruns12:17
DocScrutinizer05turns even12:17
