IP29K vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP29K and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6) and liquid protection (level 9K vs 1). IP29K is rated for > 12.5 mm — finger and high-pressure, high-temp water jets, while IP61 provides dust-tight and vertically dripping water.
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.
IP61 is an ingress protection code that ensures dust-tight (no ingress of dust) and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 1.

The exact difference (IP29K vs IP61)
Solid protection
IP29K
Level 2 — > 12.5 mm — Finger
IP61
Level 6 — Dust-Tight
IP29K provides "> 12.5 mm — Finger" (level 2), while IP61 provides "Dust-Tight" (level 6). IP61 is 4 levels higher.
Liquid protection
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
IP61
Level 1 — Vertically Dripping Water
IP29K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP29K provides 8 levels more liquid protection.

Recommendation
IP29K offers higher overall protection than IP61. Choose IP29K for harsher environments; IP61 may suffice for milder conditions and can be more cost-effective.
