IP02 vs IP11
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP02 and IP11 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 1) and liquid protection (level 2 vs 1). IP02 is rated for no protection and dripping water at 15° tilt, while IP11 provides > 50 mm — back of hand and vertically dripping water.
Engineered to deliver no protection against solid objects and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. Classified as IEC 60529 ingress protection code IP02, it pairs solid level 0 with liquid level 2.
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 (IP02 vs IP11)
Solid protection
IP02
Level 0 — No Protection
IP11
Level 1 — > 50 mm — Back of Hand
IP02 provides "No Protection" (level 0), while IP11 provides "> 50 mm — Back of Hand" (level 1). IP11 is 1 level higher.
Liquid protection
IP02
Level 2 — Dripping Water at 15° Tilt
IP11
Level 1 — Vertically Dripping Water
IP02 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP11 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP02 provides 1 level more liquid protection.
