The JST PHDR-24VS is a 24-position receptacle housing from the PHD series, a 2.00mm-pitch dual-row wire-to-board connector family. It is the female half of the connection, designed to accept crimp-terminated female socket contacts and mate with the corresponding PHD series pin header.
To populate it, you need the matching JST PHD series female crimp socket terminals, ordered separately. The mating half is a JST PHD series pin header (through-hole or SMT, straight or right-angle, depending on board layout). Do not order half a connection — confirm both the crimp terminal part number and the header part number for the full interconnect.
