IP58 vs IP69K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP69K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 8 vs 9K). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP69K provides dust-tight and high-pressure, high-temp water jets.
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.
IP69K is dust-tight and resists high-pressure (8–10 MPa), high-temperature (80 °C) water jets. The highest IP rating, required for food, beverage, and pharmaceutical washdown environments.

The exact difference (IP58 vs IP69K)
Solid protection
IP58
Level 5 — Dust-Protected
IP69K
Level 6 — Dust-Tight
IP58 provides "Dust-Protected" (level 5), while IP69K provides "Dust-Tight" (level 6). IP69K is 1 level higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP69K
Level 9 — High-Pressure, High-Temp Water Jets
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP69K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP69K provides 1 level more liquid protection.

Recommendation
IP69K offers higher overall protection than IP58. Choose IP69K for harsher environments; IP58 may suffice for milder conditions and can be more cost-effective.
