IP09K vs IP22
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP09K and IP22 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 9K vs 2). IP09K is rated for no protection and high-pressure, high-temp water jets, while IP22 provides > 12.5 mm — finger and dripping water at 15° tilt.
The IP09K rating offers no protection against solid objects and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 9K.
IP22 protects against fingers and 12.5 mm objects, plus vertically dripping water when tilted up to 15°. Common for indoor equipment that may encounter occasional condensation or drips.

The exact difference (IP09K vs IP22)
Solid protection
IP09K
Level 0 — No Protection
IP22
Level 2 — > 12.5 mm — Finger
IP09K provides "No Protection" (level 0), while IP22 provides "> 12.5 mm — Finger" (level 2). IP22 is 2 levels higher.
Liquid protection
IP09K
Level 9 — High-Pressure, High-Temp Water Jets
IP22
Level 2 — Dripping Water at 15° Tilt
IP09K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP22 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP09K provides 7 levels more liquid protection.

Recommendation
IP09K offers higher overall protection than IP22. Choose IP09K for harsher environments; IP22 may suffice for milder conditions and can be more cost-effective.
