IP65 vs IP09K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP65 and IP09K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 0) and liquid protection (level 5 vs 9K). IP65 is rated for dust-tight and water jets (6.3 mm nozzle), while IP09K provides no protection and high-pressure, high-temp water jets.
IP65 is dust-tight and resists low-pressure water jets (6.3 mm nozzle, 30 kPa). It is the most common standard for fully exposed outdoor electronics such as lighting, cameras, and EV chargers.
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 (IP65 vs IP09K)
Solid protection
IP65
Level 6 — Dust-Tight
IP09K
Level 0 — No Protection
IP65 provides "Dust-Tight" (level 6), while IP09K provides "No Protection" (level 0). IP65 is 6 levels higher.
Liquid protection
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP09K
Level 9 — High-Pressure, High-Temp Water Jets
IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP09K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP09K provides 4 levels more liquid protection.

Recommendation
IP65 offers higher overall protection than IP09K. Choose IP65 for harsher environments; IP09K may suffice for milder conditions and can be more cost-effective.
