IP58 vs IP11
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP11 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 1) and liquid protection (level 8 vs 1). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP11 provides > 50 mm — back of hand and vertically dripping water.
IP58 is dust-protected and rated for continuous immersion in water under manufacturer-specified conditions. A niche rating for equipment that must operate submerged while allowing limited dust ingress.
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 (IP58 vs IP11)
Solid protection
IP58
Level 5 — Dust-Protected
IP11
Level 1 — > 50 mm — Back of Hand
IP58 provides "Dust-Protected" (level 5), while IP11 provides "> 50 mm — Back of Hand" (level 1). IP58 is 4 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP11
Level 1 — Vertically Dripping Water
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP11 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP58 provides 7 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP11. Choose IP58 for harsher environments; IP11 may suffice for milder conditions and can be more cost-effective.
