IP48 vs IP63
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP48 and IP63 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 8 vs 3). IP48 is rated for > 1 mm — small wires and continuous immersion (manufacturer-specified), while IP63 provides dust-tight and spraying water (up to 60°).
Engineered to deliver protection against solid objects larger than 1.0 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. Classified as IEC 60529 ingress protection code IP48, it pairs solid level 4 with liquid level 8.
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 (IP48 vs IP63)
Solid protection
IP48
Level 4 — > 1 mm — Small Wires
IP63
Level 6 — Dust-Tight
IP48 provides "> 1 mm — Small Wires" (level 4), while IP63 provides "Dust-Tight" (level 6). IP63 is 2 levels higher.
Liquid protection
IP48
Level 8 — Continuous Immersion (manufacturer-specified)
IP63
Level 3 — Spraying Water (up to 60°)
IP48 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP63 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP48 provides 5 levels more liquid protection.

Recommendation
IP48 offers higher overall protection than IP63. Choose IP48 for harsher environments; IP63 may suffice for milder conditions and can be more cost-effective.
