Under powering solenoids

Hey all,

Just a quick question - I can't seem to find an answer on Google (yet).

I have a couple of solenoids for a project I'm working on - and just wondering what bad could happen if I power then with less than the 'required' (read: printed on solenoid) voltage.

I don't have/can find the data sheets for these (although I think I may have found one, but it covers a very wide range of them) so I'll try best to describe them.

One is a sear solenoid - basically a round cylinder with a small plunger. Has 9VDC-PD printed under the part # EMESSEM 9954 0328 (which brings up nothing)

The other is a pneumatic 5 way (or so I'm told). Has printed 6VDC and the cable is red/black. Part number is SYJ3140-VG-X70-Q. This is what I think might be the datasheet for it.

While I do care about the speed at which they run at - it would be nice if I could run everything off 5V for simplicity sake. But due to the hard-to-find nature of these parts I want to be sure I won't cause them any undue damage by running them low.

Thanks for the help

I want to be sure I won't cause them any undue damage by running them low.

Be assured that no damage will occur by under powering them.
