IP09K vs IP17
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP09K and IP17 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 1) and liquid protection (level 9K vs 7). IP09K is rated for no protection and high-pressure, high-temp water jets, while IP17 provides > 50 mm — back of hand and temporary immersion (up to 1 m).
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.
Built to withstand protection against solid objects larger than 50 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. Classified as IEC 60529 ingress protection code IP17, it pairs solid level 1 with liquid level 7.

The exact difference (IP09K vs IP17)
Solid protection
IP09K
Level 0 — No Protection
IP17
Level 1 — > 50 mm — Back of Hand
IP09K provides "No Protection" (level 0), while IP17 provides "> 50 mm — Back of Hand" (level 1). IP17 is 1 level higher.
Liquid protection
IP09K
Level 9 — High-Pressure, High-Temp Water Jets
IP17
Level 7 — Temporary Immersion (up to 1 m)
IP09K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP17 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP09K provides 2 levels more liquid protection.

Recommendation
IP09K offers higher overall protection than IP17. Choose IP09K for harsher environments; IP17 may suffice for milder conditions and can be more cost-effective.
