Hello,

I have a card (which is not a motherboard but I don't really know where to ask my question...) with a 32-pin connector.

This connector is connected to another card with the same connector: the two plug into each other, and since there are no wires, the contacts must be very good.

Does anyone know what this connector is called?

Thank you

It is indeed probably a DIN 41612, more commonly known in the industry as a HARTING connector, and it can be used for many things, such as connecting a pocket or a control terminal, a printer, sensors, etc. It is the card that will define its use, not the port itself.

Hello,

Yes, 32 pins, it looks like a DIN 41612 connector.

A I/O card? A module, more information is welcome...

Thanks friends, you were right!

I find them a bit expensive, but I found some on Ali to test...

-> an I/O card? a module with more information would be welcome...

These are connectors used in old DACs to link different digital cards that need to communicate with each other:

-between the card decoding SPDIF signals and the calculator card featuring 2 FPGAs and 2 DSPs. There is 1 connector to link these two cards.

-and between the calculator card (mentioned above) and the 2 conversion cards equipped with DAC chips. There are 2 connectors (one for each channel).

As I'm working on similar cards, I was thinking of using IDC connectors (easy to find and inexpensive), but using a ribbon cable to connect two IDCs together doesn't inspire confidence.

I'm wary of interference sensitivity from the IDC ribbon cable, and maybe the signal frequency could cause issues with the same IDC cable (?). The connections would remain short (10cm) but I'm not sure.

These DIN41612 connectors seem to guarantee better connections??

In your opinion, could IDC connectors work??

Hello,

Because you trust any electronic equipment sold on AliExpress?

Hello,

Yes, an IDC cable on 10cm can work, take a shielded one to reduce noise interference.

No obviously, but for testing it will be fine....

->Yes, an IDC cable of 10cm can be suitable, use a shielded one to reduce interference noise.

Oh, I didn't know that shielded ribbon cable for IDC existed??? I've never seen any...

There's no need to look for a shielded ribbon cable (I also doubt the existence of shielded ribbon cables per se in computing, normally a simple ground wire integrated into the cable serves as shielding), and for this length, it's unnecessary.

That's exactly what I thought flo888: besides, I don't see how it would be possible to shield each of the ribbon cables...

My instinct tells me that the DIN-41612 connectors, which are "purely mechanical" (if I'm expressing myself correctly), should be better than two IDC with a ribbon cable in between...
