    Hall Effect sensors

    I read an article about a guy using these as a limit switch, here it is:
    http://www.balbots.com/article_info.php?articles_id=10

    I am having a difficult finding a mechanical limit switch for my needs, and its not worth buying optical. So these seem attractive at $1.04 at Digikey.

    My question is, would these be wired in just as a regular limit switch where it is normally Open or normally closed?
    Or is there something more......?

    The only Hall effects I have ever messed with have been distributor triggers in cars. So I looked around. The one the guy lists looks like it is meant to be tripped with a permanant magnet and it is just a switch, but I could not find whether it is normal open or closed(Wihtout openeing a big pdf)

    It needs Vcc and ground which an electromechanical switch doesn't require, and obviously a magnetic target. Looking at the data sheet, Vcc can be a fairly wide range. Other than that, you would use it pretty much as you would use a switch.

    It is really refreshing when you have a sore throat.

    Life is about hanging onto what you think is important and finding out what really is important.
    "Stop Ruining my joke!", "No, a joke implies humor attached at no additional cost"
    So many sayings, so little sig space.
