content: Salvaged a nice document scanner from a dumpster, but the power supply was lost.And it doesn't use a regular barrel connector, rather one looking like the attached picture.Tried Digikey searching and browsing product pages, as well as Google image search... Anyone know what manufacturer/model this is?There a thousands if not millions of connectors with a rounded bottom part, but this one has a hexagonal-shaped lower part...Thanks!

content: Looks like a Molex FIT- series, probably a Mini-Fit Jr. or something but probably a custom version so you won't be able to find one with the exact keying that your connector has but you should be able to make a "standard" model one work but might have to cut/file a bit here or there to make it fit.For testing you could probably use many different variety of socket contacts just individually stuck on the end of three wires or even just wires shoved into the pin shrouds... At least then you could test the scanner to be sure it works before you bother to track down a compatible connector...

content: It would be a lot easier to help you if you told us the make and model of the scanner!Ed

It's an HP ScanJet 7000n series.Been looking all through HP's docs, but it's not like they provide service manuals for those kind of devices..Easiest is prob to just desolder the existing and put in something from the parts bin..

content: Actually, maybe an old power connector from a harddrive (+ a sharp knife or a dremel) could do the trick....

content: These could be custom connectors. For testing, I'd cobble up whatever I could. If I wanted something permanent, I'd just buy a replacement adapter. I saw one on ebay for $30.Ed

content: Heh, I already knew it was one of those HPs, they used those connectors for ages... I have tons of them!My advice still stands, they are a custom version of a standard Molex connector, like all HP stuff from that era...

content: Thanks guys, appreciate the responses!I'll put something together, no worries. A few separate individual sockets and some epoxi will do the trick, if nothing else...

content: I stumbled onto the actual connector - it's not a custom one, and it's available today, it seems.It's a Molex 67969-0001,http://eu.mouser.com/ProductDetail/Molex/67969-0001/?qs=EuyFtE1skidA7JB%252b1%2fKIcw%3d%3d/g

content: Here's a trick. Does the local electronics superstore have a free electronics drop-off? They are usually overflowing with things like that.Either bring in some other electronics junk and swap for it, or talk to the kid in that area to see if there is one around.
