#139866 - What do you know about inductive power coupling? |
Ive got a product which has a strain gauge sitting on a rotating shaft and we currently have some signal conditioning stuff on there and then the power supply and serial data out is via brushes and slip rings,we came up with a veraion wich uses optical coupling for the data but now they want to do contactless power as well which is a bit more tricky,any ideas? |

| nah. | 01/01/70 00:00 | |
| it all depends on the dimensions... | 01/01/70 00:00 | |
| if you can get to the end of the shaft ... | 01/01/70 00:00 | |
