IP56 vs IP6X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP56 and IP6X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 6 vs 0). IP56 is rated for dust-protected and powerful water jets (12.5 mm nozzle), while IP6X provides dust-tight and no protection.
IP56 is dust-protected and resists powerful water jets (12.5 mm nozzle, 100 kPa). Suited to outdoor equipment subjected to heavy rain or hose-directed water.
IP6X is fully dust-tight—no ingress of dust whatsoever—with water protection not specified. The highest solid-protection rating, used where complete dust exclusion is critical.

The exact difference (IP56 vs IP6X)
Solid protection
IP56
Level 5 — Dust-Protected
IP6X
Level 6 — Dust-Tight
IP56 provides "Dust-Protected" (level 5), while IP6X provides "Dust-Tight" (level 6). IP6X is 1 level higher.
Liquid protection
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP6X
Level 0 — No Protection
IP56 provides "Powerful Water Jets (12.5 mm nozzle)" (level 6), while IP6X provides "No Protection" (level 0). IP56 is 6 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP6X. Choose IP56 for harsher environments; IP6X may suffice for milder conditions and can be more cost-effective.
