    Inspecting magnetic force necessary to activate a reed switch

    thank you it seems that going for 3-4 mm is unpractical because of weakness I am forced to go for the y-30 i found because i received a .38 USD price for this size without any holes or tooling , and this is certainly a good price for me, it goes up to 0.8 USD with express which is also an...

    Inspecting magnetic force necessary to activate a reed switch

    Guys, I really need an answer to this question , I know that y-30 is a low force magnet but if i use it in 10 mm thickness wouldn't be enough to activate this reed switch from two layers of trunk PVC? because i found a cheap source for it and i need to know the answer has anyone tried to...

    Inspecting magnetic force necessary to activate a reed switch

    Thank you very much RyreInc, that is really a good feed back, since you know a bit about magnets prices do you think if i reduced the thickness to 3mm instead of 10 it will cost around 5 $ and still do the job from behind two layers thickness of PVC wire trunks, if so do you think this cost...

    Inspecting magnetic force necessary to activate a reed switch

    thank you IRstuff for your remark, to make things clearer for you and for all I need to mention that there shouldn't be any cut in signal in any switch at anytime so as you know the two switches are vertically above each other once the magnet starts to slide against the first one the first is...

    Inspecting magnetic force necessary to activate a reed switch

    Thank you RyreInc for your feed back, I just need to let you know that yes it is a thru-magnetized along the length so the right side of the magnet length is one pole and the other is the other pole, about the type I am not that expert but i found that magnets are numbered N35 through N52 the...

    Inspecting magnetic force necessary to activate a reed switch

    thank you all for your feed back, I have reviewed a data sheet concerning the use of reed switch by a manufacturer and as i understood it would be best if the N pole of the magnet is opposite the S of the reed switch and of course the S of the magnet should be opposite the N and so I considered...

    Inspecting magnetic force necessary to activate a reed switch

    I forgot to mention that the magnet will be split vertically in terms of magnitude so if you look at it standing vertically with 140mm length the right side would be the S pole while the left side would be the N pole or visa versa, I would appreciate the help

    Inspecting magnetic force necessary to activate a reed switch

    hi, I am working on a project where i have to activate a 6AT reed switch from a distance of about 10 mm or a little more, I am going to use 10 mm X13 mm X 140 mm magnet will it have enough force to activate this switch I need to know before I try to get this large magnet volume because it will...
