IP67 vs IP11
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP11 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 1) and liquid protection (level 7 vs 1). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP11 provides > 50 mm — back of hand and vertically dripping water.
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.
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.

The exact difference (IP67 vs IP11)
Solid protection
IP67
Level 6 — Dust-Tight
IP11
Level 1 — > 50 mm — Back of Hand
IP67 provides "Dust-Tight" (level 6), while IP11 provides "> 50 mm — Back of Hand" (level 1). IP67 is 5 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP11
Level 1 — Vertically Dripping Water
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP11 handles 0.1 mm/min drip rate (Vertically Dripping Water). 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.
