I am selecting the components to use for a tester I am developing.
I am looking at various types of board to board connectors.
The requirements are:
- Rated to least 2A.
- Rated to ~200v.
- *High Isolation, in the order of 1Gohm (most important)
- Pitch no less then 1mm.
- 2 rows preferred.
- Available in large sizes, 50-200 range.
In the past I have used card edge but it has always been hard to get in and out and the connectors don't always make good contact.
Another connector I am looking at is the rectangular board to board connectors. They look promising but I don't know what the isolation resistance for these are though.
Also there is DB connectors which have high current ratings and isolation resistance for the expensive ones. How do these compare to the ones above?
Most connector datasheets I see just talk about the dimensions and footprint. It is hard to tell what type of connector is best suited for high isolation while also being able to meet all the other requirements.
Has anyone also had a design that required accurate sourcing and sensing of multiple channels or know of anything purpose built for this kind of thing?
