hi 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.
<DocScrutinizer05>
how much external magnetism would I need to saturate that design completely so it doesn't work anymore?
<DocScrutinizer05>
or is it possible at all to saturate such sensor?
<DocScrutinizer05>
maybe I should try a way too high frequency external alternating magnetic field, so the signal drowns in noise?
* DocScrutinizer05
idly wonders what's the noise immunity of the circuit consuming the signal from this sensor anyway
<DocScrutinizer05>
maybe the idea to just introduce some iron dust into the system, to clog the sensor with it, is the better idea ;-)
<DocScrutinizer05>
however I'm afraid even that won't work in the end
<DocScrutinizer05>
prolly time to apply some field change order to the electronic circuit after the sensor ;-D
<DocScrutinizer05>
integrating this thing into a usual car electric connector and hiding it under some shrinktube shouldn't be difficult and look pretty normal
<DocScrutinizer05>
any other nearby component could create a magnetic field when needed
<DocScrutinizer05>
for an interim solution a permanent magnet hidden somewhere - and removed just in case, to revert to original function - should do, eh?
