IP00 vs IP04
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP04 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 4). IP00 is rated for no protection and no protection, while IP04 provides no protection and splashing water (all directions).
IP00 offers no protection against solid objects or moisture. It is suitable only for indoor, climate-controlled environments where the equipment is fully enclosed within another protective housing.
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.

Recommendation
IP04 offers higher overall protection than IP00. Choose IP04 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
