RE: Maybe OT, ish. Power connectors.

Hi Dom,



You'll generally find that contactless is not something you are likely to
get off the shelf. It is normally designed to suit the power requirements
of
the device being used.



There is some good information on a design here.

Power wise, consider only low power for this and really best for charging
circuits.



As for the magnetic one, Google for Magnetic Power Connector. Quite a few
DIY solutions out there.





Dave.

Subject: [ukha_d] Maybe OT, ish. Power connectors.



Hi all,

I'm looking for either of:
a) magnet power connectors (mac-style) or
b) contactless power connectors.

By a) I mean the connectors which click the male/female together and
are held in place by a magnet. By b)I mean inductive power
transmitters, like as used in rechargeable toothbrushes.

In both cases, I'm really looking for off-the-shelf components, rather
than any 'diy' designs. But frankly, at the moment, I'd go with anything.

Alternatively, suggestions where I could look for such stuff - I've
tried RS and Maplins already.

Thanks,
Dom
