RS485 Connector type - Sota - 09-27-2026

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.

Do you mean the blue connectors the same as used on the comfort PCB? or the small white connectors?

The same signals are available on the blue trminal blocks and the white 4 way cable ;; 12V, COM, KA, KB

The 4 way white cable is for convenience, and is 300 mm long.
