Linear Control

I was wondering if anybody could give me a good source for a linear potentiometer. I am planning on controlling a pivot point on our robot by using some sort of device that measures linear motion. It doesn’t necessarily have to be a linear potentiometer. I know I saw some teams last year with a lever-type device on their control board that measured linear movement to control shooter speed or something… Can anyone point me in the right direction as to where to buy something like this?
Thanks a lot.

Try searching www.digikey.com for “slide”.

I think they only come in up to 45mm slides, but other on-line electronics shops might have wider selection. We managed to find some a bit longer at a little store called “Lee’s” here in Vancouver http://www.leeselectronic.com/

Just remember that you probably want the linear taper rather than the audio taper.

Good luck,

Jason
