IP12 vs IP58
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP12 and IP58 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 5) and liquid protection (level 2 vs 8). IP12 is rated for > 50 mm — back of hand and dripping water at 15° tilt, while IP58 provides dust-protected and continuous immersion (manufacturer-specified).
Designed for environments requiring protection against solid objects larger than 50 mm and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position., IP12 is an IEC 60529 code combining solid level 1 with liquid level 2.
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 (IP12 vs IP58)
Solid protection
IP12
Level 1 — > 50 mm — Back of Hand
IP58
Level 5 — Dust-Protected
IP12 provides "> 50 mm — Back of Hand" (level 1), while IP58 provides "Dust-Protected" (level 5). IP58 is 4 levels higher.
Liquid protection
IP12
Level 2 — Dripping Water at 15° Tilt
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP12 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP58 provides 6 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP12. Choose IP58 for harsher environments; IP12 may suffice for milder conditions and can be more cost-effective.
