Question 5 and 7 pin connectors

Folks:

I am considering building a 2-chassis dual mono preamp, and will need at least a 5 pin connector on both chassis and the umbilical (chassis ground, left channel V+ and V-, right channel V+ and V-). If the channels require their own grounds as well, I'll need a 7 pin connector. I was thinking about adding 2 more pins for LEDs on the line amp chassis, but this is getting ridiculous.

Does anyone know of a good source for 5 and 7 pin connectors?

What the heck -- how about 9 pin connectors (are those computer connectors substantial enough to carry the current)?

Thanks,
Scott

You can use DIN connectors. They are availabe, afaik, with up to eight pins. They are available in almost every electronics store.

The computer connectors are specified for a couple of amperes. I dont remember exactly, but it is something like 3 to 5.

I have used 9-pin "D" connectors to feed power and control signals to a preamp. It had a motorised pot and relays to switch inputs, so there was a fair bit of current, and there has been no degradation of the contacts in over 5 years. I used a standard serial data cable too, one that has all the pins wired, (some are available with only data in and data out connected).
This was so successful that I am about to use the same principle for my latest amp.

check out allelectronics.com. Just took a cursory look and found this:

Looks like this might just fit the bill.

Good Luck,

By any means--do avoid the old DIN plugs.....
D-plugs - or Sub-D more correctly- is a cost efficient solution...XLRs will also do fine
If cost is no object - go for Bendix or Amphenol bayonet MS type plugs....

I see no reason why DIN plugs should be avoided. They are available in solid metal with Renk lock. See


here.

I know which plugs you mean.....and theres a myriad of other types and makes out there....

I still won't trust DINs for feeding power though..............

This may be a matter of personal preference. There is no technical reason though to avoid Din plugs.
