IP09K vs IP36
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP09K and IP36 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 9K vs 6). IP09K is rated for no protection and high-pressure, high-temp water jets, while IP36 provides > 2.5 mm — tool / wire and powerful water jets (12.5 mm nozzle).
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.
The IP36 classification guarantees protection against solid objects larger than 2.5 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 6.

The exact difference (IP09K vs IP36)
Solid protection
IP09K
Level 0 — No Protection
IP36
Level 3 — > 2.5 mm — Tool / Wire
IP09K provides "No Protection" (level 0), while IP36 provides "> 2.5 mm — Tool / Wire" (level 3). IP36 is 3 levels higher.
Liquid protection
IP09K
Level 9 — High-Pressure, High-Temp Water Jets
IP36
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP09K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP36 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP09K provides 3 levels more liquid protection.

Recommendation
IP09K and IP36 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
