IP41 vs IP50
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP41 and IP50 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 5) and liquid protection (level 1 vs 0). IP41 is rated for > 1 mm — small wires and vertically dripping water, while IP50 provides dust-protected and no protection.
Under IEC 60529, IP41 specifies protection against solid objects larger than 1.0 mm 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 4 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.
