IP29K vs IP52
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP29K and IP52 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 5) and liquid protection (level 9K vs 2). IP29K is rated for > 12.5 mm — finger and high-pressure, high-temp water jets, while IP52 provides dust-protected and dripping water at 15° tilt.
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.
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 2.

The exact difference (IP29K vs IP52)
Solid protection
IP29K
Level 2 — > 12.5 mm — Finger
IP52
Level 5 — Dust-Protected
IP29K provides "> 12.5 mm — Finger" (level 2), while IP52 provides "Dust-Protected" (level 5). IP52 is 3 levels higher.
Liquid protection
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
IP52
Level 2 — Dripping Water at 15° Tilt
IP29K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP29K provides 7 levels more liquid protection.

Recommendation
IP29K offers higher overall protection than IP52. Choose IP29K for harsher environments; IP52 may suffice for milder conditions and can be more cost-effective.
