IP56 vs IP5X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP56 and IP5X are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 6 vs 0). IP56 is rated for dust-protected and powerful water jets (12.5 mm nozzle), while IP5X provides dust-protected 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.
IP5X is dust-protected (limited ingress, no harmful deposit) with water protection not specified. Used where dust limitation matters but the equipment is kept dry.

The exact difference (IP56 vs IP5X)
Solid protection
IP56
Level 5 — Dust-Protected
IP5X
Level 5 — Dust-Protected
Both IP56 and IP5X share the same solid protection: Dust-Protected.
Liquid protection
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP5X
Level 0 — No Protection
IP56 provides "Powerful Water Jets (12.5 mm nozzle)" (level 6), while IP5X provides "No Protection" (level 0). IP56 is 6 levels higher.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP5X. Choose IP56 for harsher environments; IP5X may suffice for milder conditions and can be more cost-effective.
