Sucking disc solenoid?

mklotz:
Are you sure you're completing the magnetic circuit? Try lifting a smooth metal plate with a diameter somewhat larger than the diameter of the solenoid.

Sucking seems to be an Asian equivalent or characterization for solenoid operation, be it a disk-type or plunger-type solenoid. I've seen it on many translated prints (we manufacture solenoids where I work) A sucking solenoid is what we would call an ordinary pull-type solenoid. I don't know what they would call a push-type. Spitting?

I've seen the pulling force as well as the stroke distance of the solenoid referred to as suckage.

Boy am I good or what "technical term" :smart: the force might refer to the holding and not lifting power. Since the photo's of them appear to have no moving parts in the coil assembly.

Hi Guys,

Thank you all very much for the words of wisdom and advice :D

The circuit is just 2 wires straight to the wall wart so yeah is connected OK. :zap:

I agree, I don't see how 3 watts can produce a 2.5kg force. :scratch:

Happily I only want it to pick up swarf from the mill and the lathe so it only needs to be a bit better than it is.

I'll have to contact the seller and see what he can tell me, it could certainly be faulty. :hammer:

Martin,
For swarf pickup, one of these is handy http://mikesworkshop.weebly.com/handy-swarf-pick-up-tool.html .

Mike gave me one, and it's great for cleaning up. Just wave it around over the chips, then hold it over the waste bin and use the screw in the side to pull the magnet away from the end so the junk drops off . No good for non-magnetic stuff, of course.
No wires, batteries or other inconveniences :D .
