IP48 vs IP52
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP48 and IP52 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 5) and liquid protection (level 8 vs 2). IP48 is rated for > 1 mm — small wires and continuous immersion (manufacturer-specified), while IP52 provides dust-protected and dripping water at 15° tilt.
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.
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 2.

The exact difference (IP48 vs IP52)
Solid protection
IP48
Level 4 — > 1 mm — Small Wires
IP52
Level 5 — Dust-Protected
IP48 provides "> 1 mm — Small Wires" (level 4), while IP52 provides "Dust-Protected" (level 5). IP52 is 1 level higher.
Liquid protection
IP48
Level 8 — Continuous Immersion (manufacturer-specified)
IP52
Level 2 — Dripping Water at 15° Tilt
IP48 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP48 provides 6 levels more liquid protection.

Recommendation
IP48 offers higher overall protection than IP52. Choose IP48 for harsher environments; IP52 may suffice for milder conditions and can be more cost-effective.
