IP69K vs IP29K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP69K and IP29K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 2). IP69K is rated for dust-tight and high-pressure, high-temp water jets, while IP29K provides > 12.5 mm — finger and high-pressure, high-temp water jets.
IP69K is dust-tight and resists high-pressure (8–10 MPa), high-temperature (80 °C) water jets. The highest IP rating, required for food, beverage, and pharmaceutical washdown environments.
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.

The exact difference (IP69K vs IP29K)
Solid protection
IP69K
Level 6 — Dust-Tight
IP29K
Level 2 — > 12.5 mm — Finger
IP69K provides "Dust-Tight" (level 6), while IP29K provides "> 12.5 mm — Finger" (level 2). IP69K is 4 levels higher.
Liquid protection
IP69K
Level 9 — High-Pressure, High-Temp Water Jets
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
Both IP69K and IP29K share the same liquid protection: High-Pressure, High-Temp Water Jets.

Recommendation
IP69K offers higher overall protection than IP29K. Choose IP69K for harsher environments; IP29K may suffice for milder conditions and can be more cost-effective.
