Where can I get this connector

Is this a 7 pin din connector?

a couple of our old tube mics have the female version on the psu side and I am looking for the male version in the photo. Someone’s cart or stand rolled over the cable at the studio and damaged the cable.

 

[Whoops]

From what microphone is that connector?

From what microphone is that connector?

We have two cables with this connector, one is for a KM256 and the other a KM54. Both mics have the correct connector going to the mic, this is the connector going into the PSU. When I pulled the connector apart to see about repair, pins started to fall out. I rather just replace the connector...

 

[Whoops]

I don’t know the name of that connector,
But as it’s on the PSU side maybe is not a bad idea to change both female and male connectors for something more modern and easily available

this one ?
https://at.rs-online.com/web/p/din-steckverbinder/0491065i would think , so
iirc rode classic uses something like that , too

 

[Whoops]

Ive used the gx16 or gx20 aviation connectors on Tube Mics PSUs, they work very well are affordable and easily available.

there’s also the different variety of multipin Binder connectors

Also the XLR 7 pin from Neutrik are quite good also

 

[pucho812]

Yes. I do the 7 pin xlr’s on builds

Make sure you buy the right make because most of the regular types are not rated above 50V.

Indeed. I may just stick with the 7 pin dins however when I pulled the connector part to have a look at it yesterday, pins started to come out so I had to be extra extra carful.

Hi Ian, I have often wondered about this. Obviously we all know that tube mics are made and sold that use these connectors. But I wonder if the very low current (<10ma) of the B+ means this spec is OK? Perhaps it is about total power, not actual voltage? Not like 150vdc is likely to arc! -Mike

^ right. I believe there would be a derating/uprating curve. It's always a voltage rating at a current.

I looked up once what current Neutrik XLRs are rated at: 16A, but I don't remember voltage rating. I needed the info for PSU connection and that's below 50V anyways, so it seems possible.

well neutrik specs

Rated current per contact	5 A
Rated voltage	< 50 V

but at a B+ thats a few ma I think it's o.k., many a company has used them without issue.

Remember that many connectors are rated at <50V because it allows to pass them under the low-voltage certification. The cost and liabilities of going to high voltage is prohibitive, even for Neutrik.

Where did you get those specs?

From Neutrik, for the gold-plated NC3FXX-B:

https://www.neutrik.com/en/product/nc3fxx-b?c=audio

Rated current per contact

16 A

It's the same for silver-plated contacts.

 

[abbey road d enfer]

16A is for the 3-pin XLR's. The 7-pin is rated at 5A.

 

[moamps]

Switchcraft 7pin XLR is rated for 125Vac
Amphenol 7pin XLR is rated for 133V

No Love for the GX16 or GX20 Aviation Connectors?

I use the four and five pin versions for PSU connectors for racking modules quite often when an external supply is required. I have not tried them on mic PSUs yet.

It would be nice if the published a curve vs a "spec".
