I found the following footprint (image below) somewhere on the internet for a screw terminal I want to use. In my opinion it seems quite ambiguous on a 2 pin screw terminal how the component will be oriented. I have 4 of them next to each other and I want to orient them so that the wires are fed in from the sides. I noticed there is a corner missing on the front silkscreen outlining the screw terminal, but I am not sure if the wires are fed in through that same side?
What is the standard demarcation for the side the wires are put into a screw terminal? I want to edit this footprint so there is no guessing involved but I could not find a standard way to do this on the internet.
Do you have a link to the datasheet? If that isn’t a footprint offered by the manufacturer then you have to verify it anyhow. These things look symmetrical so there shouldn’t be a problem as long as you know which terminal is which. Well, it could be an optical illusion but the hole sizes look different.
Is there a way to make the orientation more clear?
All 4 screw terminals are the same. So there will be no problems to identify which one is which.
I have checked the footprint and it matches the measurements on the datasheet to my judgement: 1808301529_Ningbo-Kangnex-Elec-WJ301V-5-0-2P_C8475.pdf (193.8 KB)
The hole sizes are the same. It looked like that to me too. But I checked them and they are both 1.3mm
I was going to have the pcb assembled by another party. That is why I was concerned. The footprint in your screenshot is more clear. I will download and replace it. Thank you very much!
