IP20 vs IP6X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP20 and IP6X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6). IP20 is rated for > 12.5 mm — finger and no protection, while IP6X provides dust-tight and no protection.
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.
IP6X is fully dust-tight—no ingress of dust whatsoever—with water protection not specified. The highest solid-protection rating, used where complete dust exclusion is critical.

Solid protection
IP20
Level 2 — > 12.5 mm — Finger
IP6X
Level 6 — Dust-Tight

NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP6X offers higher overall protection than IP20. Choose IP6X for harsher environments; IP20 may suffice for milder conditions and can be more cost-effective.
