YOu will most likely need a potentiometer.

Recommended values is 2K to 10K. Make sure you use Linear pot (some are available as Logarithmic)

Potentiometers are very innexpensive and readily available. However, being a mechanical component, they are subject to wear.

Make sure that you use a high quality potentiometer, that it is sealed so that dust doesnt go in, and mount it in a position where it it not going to be exposed to the elements.

<P style="MARGIN: 0in 0in 0pt"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Verdana">I found a Contactless Rotary Position Sensor from Penny-Giles PN SRH280-360A-D-68-A. It is has a log life because it is contactless but it is pricy at $210.00 each. I will be using this on a vehicle that could be subjected to some dirt or mud. Is this overkill or is it worth the money.</SPAN>

This would be a top product. You would need the Analog Output version. It may be an overkill in that it provides much more resolution than the controller can use, but it would work.

Aternatively, look for string pots in our third party suppliers links <A href="dev.roboteq.com/dev1/links.html" target=_blank>dev.roboteq.com/dev1/links.html
