IP61 vs IP69K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP61 and IP69K are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 1 vs 9K). IP61 is rated for dust-tight and vertically dripping water, while IP69K provides dust-tight and high-pressure, high-temp water jets.
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.
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.

The exact difference (IP61 vs IP69K)
Solid protection
IP61
Level 6 — Dust-Tight
IP69K
Level 6 — Dust-Tight
Both IP61 and IP69K share the same solid protection: Dust-Tight.
Liquid protection
IP61
Level 1 — Vertically Dripping Water
IP69K
Level 9 — High-Pressure, High-Temp Water Jets
IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP69K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP69K provides 8 levels more liquid protection.

Recommendation
IP69K offers higher overall protection than IP61. Choose IP69K for harsher environments; IP61 may suffice for milder conditions and can be more cost-effective.
