IP22 vs IP48
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP22 and IP48 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 4) and liquid protection (level 2 vs 8). IP22 is rated for > 12.5 mm — finger and dripping water at 15° tilt, while IP48 provides > 1 mm — small wires and continuous immersion (manufacturer-specified).
IP22 protects against fingers and 12.5 mm objects, plus vertically dripping water when tilted up to 15°. Common for indoor equipment that may encounter occasional condensation or drips.
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 exact difference (IP22 vs IP48)
Solid protection
IP22
Level 2 — > 12.5 mm — Finger
IP48
Level 4 — > 1 mm — Small Wires
IP22 provides "> 12.5 mm — Finger" (level 2), while IP48 provides "> 1 mm — Small Wires" (level 4). IP48 is 2 levels higher.
Liquid protection
IP22
Level 2 — Dripping Water at 15° Tilt
IP48
Level 8 — Continuous Immersion (manufacturer-specified)
IP22 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP48 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP48 provides 6 levels more liquid protection.

Recommendation
IP48 offers higher overall protection than IP22. Choose IP48 for harsher environments; IP22 may suffice for milder conditions and can be more cost-effective.
