IP29K vs IP5X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP29K and IP5X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 5) and liquid protection (level 9K vs 0). IP29K is rated for > 12.5 mm — finger and high-pressure, high-temp water jets, while IP5X provides dust-protected 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.
IP5X is dust-protected (limited ingress, no harmful deposit) with water protection not specified. Used where dust limitation matters but the equipment is kept dry.

The exact difference (IP29K vs IP5X)
Solid protection
IP29K
Level 2 — > 12.5 mm — Finger
IP5X
Level 5 — Dust-Protected
IP29K provides "> 12.5 mm — Finger" (level 2), while IP5X provides "Dust-Protected" (level 5). IP5X is 3 levels higher.
Liquid protection
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
IP5X
Level 0 — No Protection
IP29K provides "High-Pressure, High-Temp Water Jets" (level 9), while IP5X provides "No Protection" (level 0). IP29K is 9 levels higher.

Recommendation
IP29K offers higher overall protection than IP5X. Choose IP29K for harsher environments; IP5X may suffice for milder conditions and can be more cost-effective.
