TDK TAS Series TMR sensors


Was looking at the recent featured product page here:

Applications include motor sensing, but there’s nothing in the datasheets or website about bandwidth. I assume since the tech was used in hard drives, that 10k rpm is probably achievable? Any additional info on this?


Hi Daniel,
I have forwarded your request to TDK get more information and per TDK the Analog TMR sensor can be used in GHz bandwidth since it’s used as HDD head.

If you would like share more information regarding the background of this inquiry including application, sensor that you are currently using please feel free to message me and we can look into specifics.


Thanks Aron. No application right now, I am just curious about the technology.

We often develop lots of high speed control systems as part of our larger projects, so it’s good to know what sensors are available.
