IP04 vs IP09K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP09K are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 4 vs 9K). IP04 is rated for no protection and splashing water (all directions), while IP09K provides no protection and high-pressure, high-temp water jets.
The IP04 rating offers no protection against solid objects and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 4.
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 exact difference (IP04 vs IP09K)
Solid protection
IP04
Level 0 — No Protection
IP09K
Level 0 — No Protection
Both IP04 and IP09K share the same solid protection: No Protection.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP09K
Level 9 — High-Pressure, High-Temp Water Jets
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP09K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP09K provides 5 levels more liquid protection.

Recommendation
IP09K offers higher overall protection than IP04. Choose IP09K for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
