Re: edge connectors vs. terminal block


I actually just ordered the parts that the website said were compatible. However, out of curiosity I did go out and measure. Inside-to-inside was .141", while outside to outside was .192". That means an average (should be close to center-to-center) of .160".

The connectors I bought were a little tight (.138") but not too bad.

Some of the suggestions for alternate parts have different dimensions which may not fit.

I came across an interesting idea shortly after the edge card connector to screw terminal boards were released. Scroll down the the bottom of this page:

This would seem to make wiring under the layout easier, while maintaining a reasonable amount of reliability.

I've built one as a demonstration, but it's not been installed on the layout yet to see how well it works.

If you use screw terminals, be sure to look at the wire gauges and capacities. Trying to jam more wires under a screw than the device is rated for is a sure way to have problems.
