IP20 vs IP27
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP20 and IP27 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 7). IP20 is rated for > 12.5 mm — finger and no protection, while IP27 provides > 12.5 mm — finger and temporary immersion (up to 1 m).
IP20 protects against contact with a finger and solid objects larger than 12.5 mm. It has no water protection and is intended for dry, indoor use such as consumer electronics and IT equipment.
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 (IP20 vs IP27)
Solid protection
IP20
Level 2 — > 12.5 mm — Finger
IP27
Level 2 — > 12.5 mm — Finger
Both IP20 and IP27 share the same solid protection: > 12.5 mm — Finger.
Liquid protection
IP20
Level 0 — No Protection
IP27
Level 7 — Temporary Immersion (up to 1 m)
IP20 provides "No Protection" (level 0), while IP27 provides "Temporary Immersion (up to 1 m)" (level 7). IP27 is 7 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP27 offers higher overall protection than IP20. Choose IP27 for harsher environments; IP20 may suffice for milder conditions and can be more cost-effective.
