IP01 vs IP50
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP01 and IP50 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 5) and liquid protection (level 1 vs 0). IP01 is rated for no protection and vertically dripping water, while IP50 provides dust-protected and no protection.
IP01 provides no protection against solid objects and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 1.
Under IEC 60529, IP50 specifies dust-protected (limited ingress, no harmful deposit) and no protection against water. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 0.

Recommendation
IP50 offers higher overall protection than IP01. Choose IP50 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
