The JST 02R-WPJV-2-RM(NN) is a 2-position receptacle housing from the WPJ series, designed for wire-to-wire applications where a sealed, weather-resistant connection is needed. The housing is molded in red glass-filled PBT with a latch lock that clicks home on mate — you feel and hear it seat. This is the receptacle side; it accepts female socket crimp terminals (ordered separately) and mates with the matching WPJ plug header.
Water Resistance and Environmental Rating
The WPJ series carries a JIS C 0920 Grade Level 7 rating, which is the Japanese industrial standard for water protection — equivalent to an IP67-level immersion spec. When mated with the correct plug housing and the seal grommet is in place, this connector can handle temporary submersion in 1 meter of water. That makes it a direct fit for outdoor junction boxes, marine electronics, and agricultural equipment where a standard unsealed header would corrode or short.
Wiring and Termination — What You Need to Order
This is a housing only — the note on the order code is explicit: contacts are not included. You need to source the JST WPJ female socket crimp terminals separately, then crimp them onto your wire and insert into the housing. The latch lock holds the terminal in place; the housing accepts one row of 2 positions. The free-hanging, in-line mounting means no panel cutout or PCB footprint — just crimp, insert, and mate. For a complete mated pair, order the matching WPJ plug header (male pin side) with the same 2-position count and 5.00 mm pitch.
