The housing carries a JIS C 0920 Grade Level 7 rating, meaning it withstands temporary immersion in water — suited for outdoor lighting, small appliances, or automotive interior harnesses that see splash exposure. The natural PBT body and latch holder provide a positive lock against vibration.
The 2.00mm pitch is the first fit check: it mates with any JWPF-series header or receptacle at the same pitch, so confirm the board-side header matches that spacing. The JIS C 0920 Grade Level 7 water resistance means the mated assembly (with the correct female housing and seal) can be briefly submerged — not for continuous underwater use, but enough for rain, washdown, or condensation. The latch holder locks the plug to the header; you'll hear and feel it seat.
You'll need to order the appropriate JWPF crimp terminals separately, typically the SWPJ-001T-P0.5 or similar depending on wire gauge. The housing accepts the contacts after crimping and insertion; the latch holder then retains them. Plan your BOM line to include both the housing and the terminals.
The 02T-JWPF-VSLE-S is the 2-position member. The 03T-JWPF-VSLE-S adds a third position in the same single-row, 2.00mm pitch layout, and the 04T-JWPF-VSLE-S goes to 4 positions. The 06T-JWPF-VSLE-D jumps to 6 positions in a dual-row arrangement — same pitch but a different footprint.
