IP41 vs IP63
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP41 and IP63 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 1 vs 3). IP41 is rated for > 1 mm — small wires and vertically dripping water, while IP63 provides dust-tight and spraying water (up to 60°).
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.
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 (IP41 vs IP63)
Solid protection
IP41
Level 4 — > 1 mm — Small Wires
IP63
Level 6 — Dust-Tight
IP41 provides "> 1 mm — Small Wires" (level 4), while IP63 provides "Dust-Tight" (level 6). IP63 is 2 levels higher.
Liquid protection
IP41
Level 1 — Vertically Dripping Water
IP63
Level 3 — Spraying Water (up to 60°)
IP41 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP63 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP63 provides 2 levels more liquid protection.

Recommendation
IP63 offers higher overall protection than IP41. Choose IP63 for harsher environments; IP41 may suffice for milder conditions and can be more cost-effective.
