IP43 vs IPX5
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP43 and IPX5 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 0) and liquid protection (level 3 vs 5). IP43 is rated for > 1 mm — small wires and spraying water (up to 60°), while IPX5 provides no protection and water jets (6.3 mm nozzle).
IP43 protects against 1 mm solid objects and spraying water up to 60° from vertical. A practical rating for sheltered equipment subject to light angled spray, such as covered outdoor fixtures.
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 (IP43 vs IPX5)
Solid protection
IP43
Level 4 — > 1 mm — Small Wires
IPX5
Level 0 — No Protection
IP43 provides "> 1 mm — Small Wires" (level 4), while IPX5 provides "No Protection" (level 0). IP43 is 4 levels higher.
Liquid protection
IP43
Level 3 — Spraying Water (up to 60°)
IPX5
Level 5 — Water Jets (6.3 mm nozzle)
IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IPX5 handles 30 kPa (Water Jets (6.3 mm nozzle)). IPX5 provides 2 levels more liquid protection.

Recommendation
IP43 offers higher overall protection than IPX5. Choose IP43 for harsher environments; IPX5 may suffice for milder conditions and can be more cost-effective.
