content: Does anyone know a source for this gold binding post? (apart from Altronics)http://www.altronics.com.au/index.asp?area=item&id=P2000The one on the left in the photo below with the raised panel keying is the Altronics one I want.The one on the right with just the round thread is the only one I have been able to source elsewhere after extensive searching. But I need the one with the panel keying.No, Altronics will not tell me who their source is, and charging too much, and have ridiculous lead times for bulk.Yes, I have tried countless Alibaba sources, but have had no luck.Thanks.

content: Dave, the pictures don't show the details very clearly but the seller says they do have the panel keying bit:http://item.taobao.com/item.htm?spm=a230r.1.14.219.2NfFhM&id=13198578895&_u=roemap3cb1bI can order a couple of these to have closer look if you like.

content: Those actually look like RadioShack binding posts... of course I'm not sure if they still sell them. Try searching futurlec.com or even mouser/digikey

content: Quote from: Rasz on May 27, 2013, 05:09:19 amGlue of any sort is a PITA for production unless you have a fully automatic dispensing & placement process - getting the right amount in the right place consistently, spillage, curing time etc. all slow things down and open up multiple error possibilities.

content: That and loctite only prevents rotation of the nut relative to the post. The keying with the D on it makes sure the alignment of the hole though the binding post never changes, and is always the how you intended. Binding posts that spin when you crank down on them by hand =

content: Using adhesives also has a downside, that manufacturer has to perform chemical safety assessment and all the related stuff (which varies from country to country). Of course they will happily do that for you, and same as happily charge you for it in this form or another.

content: Bennic is probably the OEM, and they do take orders directly (though I'm not sure what the MOQs would be like). I think BP11, BP18 or BP18U will be the ones you want, with the D suffix for keying.

content: Thanks, yes they look like the ones.The key on the Altronics ones are 5.13mm x 3.93mmAre the Taobao ones the same?I presume it's some sort of defacto standard of sorts?That matters because the PCB cutout has to match that and not be too loose.

content: Glad they fit well! Yes, I can help you order in volume too. Just PM me your requirements (volume, time, etc) and I will see what I can do.No need to plug my eBay store just because of this. I try not to come across too much like a “spammer” who's here just to sellIn fact, I'd much rather have more time to do some learning and experimenting myself too!Quote from: EEVblog on June 13, 2013, 06:18:28 am
