IP11 vs IP67
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP11 and IP67 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 6) and liquid protection (level 1 vs 7). IP11 is rated for > 50 mm — back of hand and vertically dripping water, while IP67 provides dust-tight and temporary immersion (up to 1 m).
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.
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.

The exact difference (IP11 vs IP67)
Solid protection
IP11
Level 1 — > 50 mm — Back of Hand
IP67
Level 6 — Dust-Tight
IP11 provides "> 50 mm — Back of Hand" (level 1), while IP67 provides "Dust-Tight" (level 6). IP67 is 5 levels higher.
Liquid protection
IP11
Level 1 — Vertically Dripping Water
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP11 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP67 provides 6 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP11. Choose IP67 for harsher environments; IP11 may suffice for milder conditions and can be more cost-effective.
