Calculation Assistance

[uidb5259]

I have been having an issue trying to make the correct magnet selection for a switch application. I have a certain reed switch that I have selected. I am having trouble trying to determine the Gauss value of a corresponding magnet required to activate the switch and the distance at which it will activate. Help please.

There is no straightforward method and you've provided no details for anyone to run a calculation.

Your best bet is to contact a reputable magnet supplier and describe the reed switch, its rating, distances, other relevant parameters.

I think you might be better off contacting the reed switch manufacture and ask them to recommend the magnet given you distance requirements.
