IP41 vs IP65
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP41 and IP65 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 1 vs 5). IP41 is rated for > 1 mm — small wires and vertically dripping water, while IP65 provides dust-tight and water jets (6.3 mm nozzle).
Under IEC 60529, IP41 specifies protection against solid objects larger than 1.0 mm and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 1.
IP65 is dust-tight and resists low-pressure water jets (6.3 mm nozzle, 30 kPa). It is the most common standard for fully exposed outdoor electronics such as lighting, cameras, and EV chargers.

The exact difference (IP41 vs IP65)
Solid protection
IP41
Level 4 — > 1 mm — Small Wires
IP65
Level 6 — Dust-Tight
IP41 provides "> 1 mm — Small Wires" (level 4), while IP65 provides "Dust-Tight" (level 6). IP65 is 2 levels higher.
Liquid protection
IP41
Level 1 — Vertically Dripping Water
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP41 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP65 provides 4 levels more liquid protection.

Recommendation
IP65 offers higher overall protection than IP41. Choose IP65 for harsher environments; IP41 may suffice for milder conditions and can be more cost-effective.
