By the way, that is not what most people call a JST connector, what most people call JST's have a different housing, pin spacing, but they also lock.
These are what are found sticking out the ends of Aristo locos, and are used internally for motors and track pickups in USAT.
The connector in question is often used for smoke or lights.
But as Tony pointed out, JST is a company, making many types of connectors. This is kind of like Xerox, where people called any copier a Xerox machine.
Funny thing, JST no longer makes these connectors!

Look at the JST website for p/n SMP-02V-BC (sockets) and SMP-02V-B (pins)
JST Connectors. It appears they do still make them. (Aristo must be getting them from somewhere).
As for the Red ones we are discussing here, they are commonly called JST-BEC connectors. JST calls them a type RCY connector.
Connectors come in a million flavors, and even if you know the actual part numbers, they can still be real confusing.
Also a note of interest ... I have seen specs on distributor's websites stating current ratings for these connectors at 5 amps. On the JST website, both of these types are only rated for 3 amps. Certainly enough for most situations, but I would rather see 5A.
