Different connectors in naming we'll notice that there are letters and numbers,so what's the meaning of connector types like PH, XH, and SM?
XKB technology company shows you the meaning here.

Terminals like PH, XH, SM are a series of connector numbers of different types and spacing produced by JST?Japan Solderless Terminal?,because JST is used the most, many domestic manufacturers are referring to the industry leader JST,therefore, most of them use such codes and add codes like PH, XH, SM to their product names that make it easier for the type pickers to know which one matches the JST,
so they can know what the product series is,and this naming method has also become a common usage in the industry.

Each code represents a series of products, and the biggest difference is the pitch.
