IP63 vs IP6X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP63 and IP6X are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 3 vs 0). IP63 is rated for dust-tight and spraying water (up to 60°), while IP6X provides dust-tight and no protection.
The IP63 classification guarantees dust-tight (no ingress of dust) and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 3.
IP6X is fully dust-tight—no ingress of dust whatsoever—with water protection not specified. The highest solid-protection rating, used where complete dust exclusion is critical.

The exact difference (IP63 vs IP6X)
Solid protection
IP63
Level 6 — Dust-Tight
IP6X
Level 6 — Dust-Tight
Both IP63 and IP6X share the same solid protection: Dust-Tight.
Liquid protection
IP63
Level 3 — Spraying Water (up to 60°)
IP6X
Level 0 — No Protection
IP63 provides "Spraying Water (up to 60°)" (level 3), while IP6X provides "No Protection" (level 0). IP63 is 3 levels higher.

Recommendation
IP63 offers higher overall protection than IP6X. Choose IP63 for harsher environments; IP6X may suffice for milder conditions and can be more cost-effective.
