The link you posted doesn't work as it has session information in the URL which means it won't work beyond the session used to access the info.
So the best way around that is to visit the main page then search from there.
for the 60A-18-4-P or whatever part you want.


BTW: Grayhill have the most logical part naming standard in ANY product I have ever seen - pity all such electronic components weren't labelled the same simple structured way.
their site has explanation of the part naming rules they follow - very simple.
