IP53 vs IP56
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP53 and IP56 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 3 vs 6). IP53 is rated for dust-protected and spraying water (up to 60°), while IP56 provides dust-protected and powerful water jets (12.5 mm nozzle).
Built to withstand dust-protected (limited ingress, no harmful deposit) and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP53, it pairs solid level 5 with liquid level 3.
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.

The exact difference (IP53 vs IP56)
Solid protection
IP53
Level 5 — Dust-Protected
IP56
Level 5 — Dust-Protected
Both IP53 and IP56 share the same solid protection: Dust-Protected.
Liquid protection
IP53
Level 3 — Spraying Water (up to 60°)
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP53 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP56 provides 3 levels more liquid protection.

Recommendation
IP56 offers higher overall protection than IP53. Choose IP56 for harsher environments; IP53 may suffice for milder conditions and can be more cost-effective.
