Some while ago we had a conversation on the Chinese 4 pin plugs and sockets.
The type usually sold are not suitable for voltages over 48 volts as they have male pins on the bulkhead sockets.

Golden Bollocks [ aka Jonathan ] came up with an alternative, I ordered a few and can't find the bastard things.

Link to the thread or seller please ?

Loads of dead links or the male fittings, can't even find the email but it might have been thru ebay and not trawling thru 100's of pages.

Anyone got a link to 4 pin female bulkhead sockets ?

Regarding the Chinese plugs, is it possible to remove the pins for soldering?

John just in case you get desperate again. These are microphone plugs, i have tons from old radios and chassis here. But local?

Thanks for the link but fired off another email to China, searched high and low and can't find the ones I bought ? but thinking about it now I might not have ordered them after all.

Still need the reversed sockets to the ones shown, it's illegal to use these on commercial equipment at greater than 30 v DC

I know it doesn't really apply as XY and Z are always connected but the A axis is mainly left unconnected and any stray chips can easily short the drivers out.

Remember I'm working on commercial metal cutting equipment and need to follow wiring regs.

Farnell do the mic plug format , can`t place link at moment.

Bulgin Mini Bucaneer are IP and voltage rated.

You used to be able to get a flip lid case for them at one time to keep dirt out. Don't know if they changes things or not? they spun as yo tightened them up as not to interfere with the locking ring.

Any ideas where to get the flanged type 4 pole :- 8637 approx 25mm square or a plug to fit it ( non screw just locking ring )

The plugs are just a standard 4 pin mic plug. That there is just a standard surface mount instead of a through chassis mount.

Sorry not sure from pic but does it have a single groove instead of a thread? if it is then it is a bayonet fitment, used a lot on army radio gear. Still a mic socket.

AudioSpares*-*Audio*Spares,*Parts,*Cables,*Studio*Spares,*Leads (http://www.audiospares.com) do a range of these 16mm connectors, they are under 1 each part and are the same (ish) as the Maplin ones but at 1/3 the price. You can collect from them (Derby) if your order is over 100.
