RS485 Connector type

[Sota]

I need to make up some custom lengths of RS485 cable, and I'm trying to identify the 4-pin connector that you use. It looks like some version of a JST connector, but I cannot find an exact match for it. Can you help?

Thanks!

We buy the cable assembly, and not the individual connectors so I am afraid we do not have the poartr numbers, but I think iis q common spec.
