I am unable to find the right mating part (connector) for this 50-mil contact pitch (supposedly) IDC socket. The groove in this particular socket has an offset, and I am unable to find any connector that fits this. The connfly website is rather unhelpful in this regard, as I am not even able to find this socket in their product list, let alone a mating part. It would be great if somebody could point me in the right direction, or has used similar sockets before.
Sometimes is better to do search by what you want. In your case: board-to-board connection and add filtering: 1.27mm pitch, 10-way.
