IP56 vs IPX5
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP56 and IPX5 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 6 vs 5). IP56 is rated for dust-protected and powerful water jets (12.5 mm nozzle), while IPX5 provides no protection and water jets (6.3 mm nozzle).
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.
IPX5 resists low-pressure water jets (6.3 mm nozzle, 30 kPa) with solid protection not specified. Used where water-jet resistance matters more than dust sealing.

The exact difference (IP56 vs IPX5)
Solid protection
IP56
Level 5 — Dust-Protected
IPX5
Level 0 — No Protection
IP56 provides "Dust-Protected" (level 5), while IPX5 provides "No Protection" (level 0). IP56 is 5 levels higher.
Liquid protection
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IPX5
Level 5 — Water Jets (6.3 mm nozzle)
IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IPX5 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP56 provides 1 level more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IPX5. Choose IP56 for harsher environments; IPX5 may suffice for milder conditions and can be more cost-effective.
