IP49K vs IP64
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP49K and IP64 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 9K vs 4). IP49K is rated for > 1 mm — small wires and high-pressure, high-temp water jets, while IP64 provides dust-tight and splashing water (all directions).
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.
IP64 is dust-tight and resists splashing water from any direction. A solid outdoor-covered rating combining complete dust exclusion with splash tolerance, sitting between IP65 (jets) and IP54 (dust-protected).

The exact difference (IP49K vs IP64)
Solid protection
IP49K
Level 4 — > 1 mm — Small Wires
IP64
Level 6 — Dust-Tight
IP49K provides "> 1 mm — Small Wires" (level 4), while IP64 provides "Dust-Tight" (level 6). IP64 is 2 levels higher.
Liquid protection
IP49K
Level 9 — High-Pressure, High-Temp Water Jets
IP64
Level 4 — Splashing Water (all directions)
IP49K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP64 handles 50–100 kPa (Splashing Water (all directions)). IP49K provides 5 levels more liquid protection.

Recommendation
IP49K offers higher overall protection than IP64. Choose IP49K for harsher environments; IP64 may suffice for milder conditions and can be more cost-effective.
