The JST 04R-JWPF-VSLE-S is a 4-position receptacle housing from the JWPF series, a sealed wire-to-board connector family built for environments where moisture ingress is a real risk. The housing carries a JIS C 0920 Grade Level 7 seal rating, which means the mated assembly with the correct contacts and plug half can handle temporary immersion; think outdoor lighting, small appliances, or automotive interior connections that might see condensation or a wash-down cycle.
Termination is crimp-style, so you'll need the matching JWPF-series crimp terminals and a JST-approved hand or auto-crimp tool.
