IP29K vs IP34
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP29K and IP34 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 3) and liquid protection (level 9K vs 4). IP29K is rated for > 12.5 mm — finger and high-pressure, high-temp water jets, while IP34 provides > 2.5 mm — tool / wire and splashing water (all directions).
With IP29K, an enclosure receives protection against solid objects larger than 12.5 mm 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 2 with second-digit (liquid) level 9K.
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 (IP29K vs IP34)
Solid protection
IP29K
Level 2 — > 12.5 mm — Finger
IP34
Level 3 — > 2.5 mm — Tool / Wire
IP29K provides "> 12.5 mm — Finger" (level 2), while IP34 provides "> 2.5 mm — Tool / Wire" (level 3). IP34 is 1 level higher.
Liquid protection
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
IP34
Level 4 — Splashing Water (all directions)
IP29K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP34 handles 50–100 kPa (Splashing Water (all directions)). IP29K provides 5 levels more liquid protection.

Recommendation
IP29K offers higher overall protection than IP34. Choose IP29K for harsher environments; IP34 may suffice for milder conditions and can be more cost-effective.
