Electric door bump thingie

[Crash Gordon]

How is that practical? You want me to start winding wire on the armature
plate?

I don't think a magnetic lock works that way when you reverse the
current. I've never tried it though, so I can't be sure.

When you order be sure to request a catalog. It is 30% bigger than
Grainger. However watch the pricing. They do seem to be a bit high but
they have the stuff you need. The other great thing is they do
not................................. (your find out if you order, don't want
to put all info on a public forum).

And the search on the website is excellent.

Do a search for electric piston.

Working on a custom maglock project. I need something like a 12v solenoid to
"bump" a hidden door opened after the maglock releases. There's no visible
means of opening the door from outside the room. Just has to bump the door
opened enough so you can grab the door to open it.

Or..any other ideas?

He's talking about the plate being magnetized... which they normally are
not. You'd have to modify it accordingly - maybe drill a few holes and
embed some small fixed magnets.
