Hi Folks, I recently purchased for ebay a sucking disc solenoid which reputably has a lift capacity of 2.5kg. It is a 20mm 12V Holding Electromagnet Lift 2.5kg Solenoid Type: HCNE1-P20/15 It is powered by 12v and has a power rating of 3 Watts. It can actually manage to lift a 6" rule if you get it near the middle and that is about it's limit. :bang: I am powering it by a 12v 15 watt wall wart, is it a case that there is not enough power from the transformer? Perhaps the unit is faulty? :( Why do they call it a sucking disc solenoid please. :scratch: Thanks for any advice. Martin |

Hi PT, Thanks for the link but I'm afraid that still doesn't answer a few of my questions like should it need more power from the wall wart etc. Martin |

If it only requires 3W, a 15W wall wart should be more than adequate to power it. If you have a car and some jump leads, try it on a car battery. But it may just be a duff Ebay item, in which a different letter should be substituted for the first S in "Sucking solenoid". I've never heard that expression before, but searching on Ebay brings up a few; all from Hong Kong, so something may have been lost in translation. All are 12v, the first allegedly needing 0.2A for 10Kg and the second (from a different seller) 0.2A for 2Kg. Something doesn't sound quite right there. 12V at 0.2A is 2.4 watts, by the way. I'm no expert on electromagnets, but 2 or 3 watts doesn't really seem sufficient to hold 2Kg. Contact the seller and if necessary start a formal dispute. Andy |

It is some kind of holding electromagentic solenoid, from what little that can be gleaned from the google search for sucking disk solenoid. All seems to be Chinese manufactures web sites or exporters or trade sites but that is the name used must be a very technical term :lol: :lol: :lol: :bugeye: |
