optical switches
Hello,
I know that this is a little off the topic but I need to use optical
switches for my robot. I was wondering if anyone knew how to hook an optical
switch. I have many of them with three and four wires. Any help would be of
great use. Specifically, what wires are connected to where. Any other
information would be of great assistance. Thanks in advance.

opto-interrupter, etc... Do you have a manufacturer and part number off the
devices you have?

Hi,
I assume you are talking about a photocell, where you pass something
in front of the optic and you get a signal out (Diffuse scan). If
so, then the usual configuration, in my experience, is
Brown=VDD (+24v)
Blue=VSS (0v)
Black=signal N/O or N/C
White=signal N/C or N/O
In some instances you may have a teach wire which allows you to set
the sensitivity.
Another type is retroflective where wires are the same but requires
something in front of a reflector to get the signal out.
Hope this helps
