IP65 vs IP49K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP65 and IP49K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 4) and liquid protection (level 5 vs 9K). IP65 is rated for dust-tight and water jets (6.3 mm nozzle), while IP49K provides > 1 mm — small wires 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.
Built to withstand protection against solid objects larger than 1.0 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. Classified as IEC 60529 ingress protection code IP49K, it pairs solid level 4 with liquid level 9K.

The exact difference (IP65 vs IP49K)
Solid protection
IP65
Level 6 — Dust-Tight
IP49K
Level 4 — > 1 mm — Small Wires
IP65 provides "Dust-Tight" (level 6), while IP49K provides "> 1 mm — Small Wires" (level 4). IP65 is 2 levels higher.
Liquid protection
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP49K
Level 9 — High-Pressure, High-Temp Water Jets
IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP49K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP49K provides 4 levels more liquid protection.

Recommendation
IP49K offers higher overall protection than IP65. Choose IP49K for harsher environments; IP65 may suffice for milder conditions and can be more cost-effective.
