Is anyone familiar with Germany’s PG thread standard?
Thread Content
I’ve just started working with instrument control systems. There’s a flow switch whose interface is PG13.5; at first I didn’t understand what that meant, but after looking it up online, I found out that PG is a German standard. Are there any technical standard manuals related to PG? Also, I need to design an electrical wiring box – what should I use to make the holes? It seems that the opening size of PG isn’t very standard
PG thread: Cylindrical thread for gas cylinders; national standard: GB/T 8335-1998
You can find the corresponding standard by searching for “PG thread standard DIN40430” on Baidu.
If what you design is to be used in China, why not use ISO20*1.5 threads? Such threads can be purchased at any hardware store around the street. Additionally, there are many companies in China that produce processing interface converters.
I wasn’t clear about it either, because this is a standard specific to cable connectors
