IP50 vs IPX4
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP50 and IPX4 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 0 vs 4). IP50 is rated for dust-protected and no protection, while IPX4 provides no protection and splashing water (all directions).
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.
IPX4 (solid protection not specified) resists splashing water from any direction. A common minimum for bathroom and outdoor-covered appliances where dust sealing is not required.

Recommendation
IP50 offers higher overall protection than IPX4. Choose IP50 for harsher environments; IPX4 may suffice for milder conditions and can be more cost-effective.
