IP61 vs IP64
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP61 and IP64 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 1 vs 4). IP61 is rated for dust-tight and vertically dripping water, while IP64 provides dust-tight and splashing water (all directions).
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.
IP64 is dust-tight and resists splashing water from any direction. A solid outdoor-covered rating combining complete dust exclusion with splash tolerance, sitting between IP65 (jets) and IP54 (dust-protected).

The exact difference (IP61 vs IP64)
Solid protection
IP61
Level 6 — Dust-Tight
IP64
Level 6 — Dust-Tight
Both IP61 and IP64 share the same solid protection: Dust-Tight.
Liquid protection
IP61
Level 1 — Vertically Dripping Water
IP64
Level 4 — Splashing Water (all directions)
IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP64 handles 50–100 kPa (Splashing Water (all directions)). IP64 provides 3 levels more liquid protection.

Recommendation
IP64 offers higher overall protection than IP61. Choose IP64 for harsher environments; IP61 may suffice for milder conditions and can be more cost-effective.
