The JST ZHR-7 is a 7-circuit receptacle housing from the ZH series, a compact 1.50 mm pitch wire-to-board connector family.
The female socket contacts (crimp style, for the matching wire gauge) must be ordered separately — that's a common sourcing trap for first-time buyers. The mating male header is a separate JST ZH series part; the receptacle housing alone won't complete the interconnect without both the crimp terminals and the header. Confirm the wire gauge and terminal part number before committing the BOM.
