Hi,
I've several cards using this edge connector but can't find any information on it.
Here is a picture of General Electric and Hneywell cards using it. And a couple of more to see the measures and details.

Any help is appreciated.

Thank you

I was going through old issues of Byte and found a card with that connector in a Steve Ciarcia article on page 30 of the September 1977 issue. There is no explanation of the connector besides calling it a "44 pin edge connector" when it was clearly 36 pins, but what is interesting is that he did it as a Vector board prototype.

these were popular in the 1960's SDS also used them on their cards.
take a look in the 60's Electronics Engineer Master and Allied Electronics catlogs in the connectors section on bitsavers
I haven't looked but Elco rings a bell as a maker of them

I worked on some industrial equipment that used mating pins like those shown above and we called them bifurcated connectors - the two fingers on each pin mated with two fingers on the other pin. Problem was over time the fingers spread and contacts became unreliable. Spend a lot of time squeezing pin fingers closer together to fix intermittent connections.
