IP49K vs IP67
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP49K and IP67 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 9K vs 7). IP49K is rated for > 1 mm — small wires and high-pressure, high-temp water jets, while IP67 provides dust-tight and temporary immersion (up to 1 m).
Built to withstand protection against solid objects larger than 1.0 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. Classified as IEC 60529 ingress protection code IP49K, it pairs solid level 4 with liquid level 9K.
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.

The exact difference (IP49K vs IP67)
Solid protection
IP49K
Level 4 — > 1 mm — Small Wires
IP67
Level 6 — Dust-Tight
IP49K provides "> 1 mm — Small Wires" (level 4), while IP67 provides "Dust-Tight" (level 6). IP67 is 2 levels higher.
Liquid protection
IP49K
Level 9 — High-Pressure, High-Temp Water Jets
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP49K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP49K provides 2 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP49K and IP67 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
