IP04 vs IP52
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP52 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 5) and liquid protection (level 4 vs 2). IP04 is rated for no protection and splashing water (all directions), while IP52 provides dust-protected and dripping water at 15° tilt.
The IP04 rating offers no protection against solid objects and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 4.
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 2.

The exact difference (IP04 vs IP52)
Solid protection
IP04
Level 0 — No Protection
IP52
Level 5 — Dust-Protected
IP04 provides "No Protection" (level 0), while IP52 provides "Dust-Protected" (level 5). IP52 is 5 levels higher.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP52
Level 2 — Dripping Water at 15° Tilt
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP04 provides 2 levels more liquid protection.

Recommendation
IP52 offers higher overall protection than IP04. Choose IP52 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
