IP09K vs IP29K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP09K and IP29K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2). IP09K is rated for no protection and high-pressure, high-temp water jets, while IP29K provides > 12.5 mm — finger and high-pressure, high-temp water jets.
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.
With IP29K, an enclosure receives protection against solid objects larger than 12.5 mm 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 2 with second-digit (liquid) level 9K.

The exact difference (IP09K vs IP29K)
Solid protection
IP09K
Level 0 — No Protection
IP29K
Level 2 — > 12.5 mm — Finger
IP09K provides "No Protection" (level 0), while IP29K provides "> 12.5 mm — Finger" (level 2). IP29K is 2 levels higher.
Liquid protection
IP09K
Level 9 — High-Pressure, High-Temp Water Jets
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
Both IP09K and IP29K share the same liquid protection: High-Pressure, High-Temp Water Jets.

Recommendation
IP29K offers higher overall protection than IP09K. Choose IP29K for harsher environments; IP09K may suffice for milder conditions and can be more cost-effective.
