3-Circuit Sealed Housing for Harness Builds
The housing carries a JIS C 0920 Grade Level 7 rating, which means it's sealed against water jets at low pressure, suited for engine-bay harnesses, outdoor lighting, or washdown equipment.
The JIS C 0920 Grade Level 7 seal is the real differentiator here: it's not an IP67 rating, but it's the Japanese equivalent for splash-proof, meaning this housing can take rain, hose spray, and condensation without wicking into the cavity. The latch lock means the connector won't back out under engine vibration or cable tug — the lock is integral to the housing, no separate retainer.
3 vs 4 Circuits — Same Pitch, Same Seal
The 04R-JWPF-VSLE-S is the 4-position version of this exact housing — same 2.00 mm pitch, same JIS C 0920 Grade Level 7 seal, same latch lock, same natural PBT material. The only difference is the cavity count: 4 circuits vs 3. Both use the same crimp terminals and mate with the same header series.
