IP04 vs IP63
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP63 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 6) and liquid protection (level 4 vs 3). IP04 is rated for no protection and splashing water (all directions), while IP63 provides dust-tight and spraying water (up to 60°).
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.
The IP63 classification guarantees dust-tight (no ingress of dust) and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 3.

The exact difference (IP04 vs IP63)
Solid protection
IP04
Level 0 — No Protection
IP63
Level 6 — Dust-Tight
IP04 provides "No Protection" (level 0), while IP63 provides "Dust-Tight" (level 6). IP63 is 6 levels higher.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP63
Level 3 — Spraying Water (up to 60°)
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP63 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP04 provides 1 level more liquid protection.

Recommendation
IP63 offers higher overall protection than IP04. Choose IP63 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
