The SHR-04V-S is a 4-position, single-row receptacle housing from JST's SH series, on a 0.039" (1.00mm) pitch.
Wiring and mating checklist
This housing accepts JST SH series female crimp terminals (order separately). The mating pin header is a JST SH series male header — typically the SMH series or equivalent single-row 1.00mm pitch header with 4 positions. Confirm the header's mounting style (through-hole or SMT) matches your board layout. The crimp termination style allows field-assembly with standard JST crimp tools; the housing provides primary retention for the terminal. No secondary lock is present, so ensure full terminal insertion and pull-test per the assembly drawing.
