IP23 vs IP63
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP23 and IP63 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6). IP23 is rated for > 12.5 mm — finger and spraying water (up to 60°), while IP63 provides dust-tight and spraying water (up to 60°).
Under IEC 60529, IP23 specifies protection against solid objects larger than 12.5 mm 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 2 with second-digit (liquid) level 3.
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.

The exact difference (IP23 vs IP63)
Solid protection
IP23
Level 2 — > 12.5 mm — Finger
IP63
Level 6 — Dust-Tight
IP23 provides "> 12.5 mm — Finger" (level 2), while IP63 provides "Dust-Tight" (level 6). IP63 is 4 levels higher.
Liquid protection
IP23
Level 3 — Spraying Water (up to 60°)
IP63
Level 3 — Spraying Water (up to 60°)
Both IP23 and IP63 share the same liquid protection: Spraying Water (up to 60°).

Recommendation
IP63 offers higher overall protection than IP23. Choose IP63 for harsher environments; IP23 may suffice for milder conditions and can be more cost-effective.
