Re: Reed switch for limits - anyone done it?

I'd like to thank all that responded, the good news (in my case) is
near 100% of that I mill is Delrin and Aluminum; neither of which
has much magnetic properties. I was planing to place the switches
against travel to shorten the contact time with the magnetic field
(it should also increase accuracy). I'd love to use hall effect but
there is a bit more electronics needed and for a Sherline that may
be overkill (but it would be more accurate).

At the same time I was considering optical (using laser LED and
detector). Very accurate but need mouting is a challenge and the
additional electronics as well. There is the cost and its only a
Sherline.

I'll let all know what I end up with and how accurate the final
product end up being.

Thanks again
