IP29K vs IP6X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP29K and IP6X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6) and liquid protection (level 9K vs 0). IP29K is rated for > 12.5 mm — finger and high-pressure, high-temp water jets, while IP6X provides dust-tight and no protection.
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.
IP6X is fully dust-tight—no ingress of dust whatsoever—with water protection not specified. The highest solid-protection rating, used where complete dust exclusion is critical.

The exact difference (IP29K vs IP6X)
Solid protection
IP29K
Level 2 — > 12.5 mm — Finger
IP6X
Level 6 — Dust-Tight
IP29K provides "> 12.5 mm — Finger" (level 2), while IP6X provides "Dust-Tight" (level 6). IP6X is 4 levels higher.
Liquid protection
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
IP6X
Level 0 — No Protection
IP29K provides "High-Pressure, High-Temp Water Jets" (level 9), while IP6X provides "No Protection" (level 0). IP29K is 9 levels higher.

Recommendation
IP29K offers higher overall protection than IP6X. Choose IP29K for harsher environments; IP6X may suffice for milder conditions and can be more cost-effective.
