IP50 vs IP58
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP50 and IP58 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 8). IP50 is rated for dust-protected and no protection, while IP58 provides dust-protected and continuous immersion (manufacturer-specified).
Under IEC 60529, IP50 specifies dust-protected (limited ingress, no harmful deposit) and no protection against water. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 0.
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.

The exact difference (IP50 vs IP58)
Solid protection
IP50
Level 5 — Dust-Protected
IP58
Level 5 — Dust-Protected
Both IP50 and IP58 share the same solid protection: Dust-Protected.
Liquid protection
IP50
Level 0 — No Protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP50 provides "No Protection" (level 0), while IP58 provides "Continuous Immersion (manufacturer-specified)" (level 8). IP58 is 8 levels higher.

Recommendation
IP58 offers higher overall protection than IP50. Choose IP58 for harsher environments; IP50 may suffice for milder conditions and can be more cost-effective.
