IP20 vs IPX7
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP20 and IPX7 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 0) and liquid protection (level 0 vs 7). IP20 is rated for > 12.5 mm — finger and no protection, while IPX7 provides no protection 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.
IPX7 resists temporary immersion up to 1 meter for 30 minutes, with solid protection not specified. Common for portable electronics that may be dropped in water.

No direct NEMA equivalent.
Recommendation
IPX7 offers higher overall protection than IP20. Choose IPX7 for harsher environments; IP20 may suffice for milder conditions and can be more cost-effective.
