IP04 vs IP27
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP27 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 4 vs 7). IP04 is rated for no protection and splashing water (all directions), while IP27 provides > 12.5 mm — finger and temporary immersion (up to 1 m).
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 IP27 classification guarantees protection against solid objects larger than 12.5 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 7.

The exact difference (IP04 vs IP27)
Solid protection
IP04
Level 0 — No Protection
IP27
Level 2 — > 12.5 mm — Finger
IP04 provides "No Protection" (level 0), while IP27 provides "> 12.5 mm — Finger" (level 2). IP27 is 2 levels higher.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP27
Level 7 — Temporary Immersion (up to 1 m)
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP27 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP27 provides 3 levels more liquid protection.

Recommendation
IP27 offers higher overall protection than IP04. Choose IP27 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
