please help find the alternative or exact match of this part “VEAM 2411 1434811 CIR030FP 28-21P”
Hello Wondey and welcome to the DigiKey TechForum.
It appears you are looking for a 37-position circular connector, with a 28-21 shell size-insert, that is panel mounted with a flange. If that is the case, I found the options linked HERE that could work for you.
If that is not the case, can you please provide more information.
