IP11 vs IP64
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP11 and IP64 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 6) and liquid protection (level 1 vs 4). IP11 is rated for > 50 mm — back of hand and vertically dripping water, while IP64 provides dust-tight and splashing water (all directions).
Engineered to deliver protection against solid objects larger than 50 mm and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP11, it pairs solid level 1 with 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 (IP11 vs IP64)
Solid protection
IP11
Level 1 — > 50 mm — Back of Hand
IP64
Level 6 — Dust-Tight
IP11 provides "> 50 mm — Back of Hand" (level 1), while IP64 provides "Dust-Tight" (level 6). IP64 is 5 levels higher.
Liquid protection
IP11
Level 1 — Vertically Dripping Water
IP64
Level 4 — Splashing Water (all directions)
IP11 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 IP11. Choose IP64 for harsher environments; IP11 may suffice for milder conditions and can be more cost-effective.
