2-Position Sealed Receptacle for Harness Builds
It carries a JIS C 0920 Grade Level 7 waterproof rating, which means it withstands temporary immersion — think rain, washdown, or splash zones on outdoor equipment, not a pressure wash. This is the female side; you pair it with the matching WPJ male header (sold separately) and load your own crimp terminals — the housing ships empty.
Waterproof Rating and What It Means
JIS C 0920 Grade Level 7 is the Japanese equivalent of IP67 — the connector is protected against temporary immersion in water up to 1 meter for 30 minutes. That makes the WPJ series a solid choice for outdoor lighting, agricultural sensors, marine electronics, or any harness that sees rain or deck washdown.
Contacts Sold Separately — What Fits
You order the female crimp terminals separately — JST part number SWPJ-001T-P0.5 or equivalent, typically for 20-24 AWG wire.
