IP69K vs IP34
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP69K and IP34 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 3) and liquid protection (level 9K vs 4). IP69K is rated for dust-tight and high-pressure, high-temp water jets, while IP34 provides > 2.5 mm — tool / wire and splashing water (all directions).
IP69K is dust-tight and resists high-pressure (8–10 MPa), high-temperature (80 °C) water jets. The highest IP rating, required for food, beverage, and pharmaceutical washdown environments.
IP34 is an ingress protection code that ensures protection against solid objects larger than 2.5 mm 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 3 with second-digit (liquid) level 4.

The exact difference (IP69K vs IP34)
Solid protection
IP69K
Level 6 — Dust-Tight
IP34
Level 3 — > 2.5 mm — Tool / Wire
IP69K provides "Dust-Tight" (level 6), while IP34 provides "> 2.5 mm — Tool / Wire" (level 3). IP69K is 3 levels higher.
Liquid protection
IP69K
Level 9 — High-Pressure, High-Temp Water Jets
IP34
Level 4 — Splashing Water (all directions)
IP69K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP34 handles 50–100 kPa (Splashing Water (all directions)). IP69K provides 5 levels more liquid protection.

Recommendation
IP69K offers higher overall protection than IP34. Choose IP69K for harsher environments; IP34 may suffice for milder conditions and can be more cost-effective.
