IP58 vs IP6X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP6X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 8 vs 0). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP6X provides dust-tight and no protection.
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.
IP6X is fully dust-tight—no ingress of dust whatsoever—with water protection not specified. The highest solid-protection rating, used where complete dust exclusion is critical.

The exact difference (IP58 vs IP6X)
Solid protection
IP58
Level 5 — Dust-Protected
IP6X
Level 6 — Dust-Tight
IP58 provides "Dust-Protected" (level 5), while IP6X provides "Dust-Tight" (level 6). IP6X is 1 level higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP6X
Level 0 — No Protection
IP58 provides "Continuous Immersion (manufacturer-specified)" (level 8), while IP6X provides "No Protection" (level 0). IP58 is 8 levels higher.

Recommendation
IP58 offers higher overall protection than IP6X. Choose IP58 for harsher environments; IP6X may suffice for milder conditions and can be more cost-effective.
