IP65 vs IP01
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP65 and IP01 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 0) and liquid protection (level 5 vs 1). IP65 is rated for dust-tight and water jets (6.3 mm nozzle), while IP01 provides no protection and vertically dripping water.
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.
IP01 provides no protection against solid objects 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 0 with second-digit (liquid) level 1.

The exact difference (IP65 vs IP01)
Solid protection
IP65
Level 6 — Dust-Tight
IP01
Level 0 — No Protection
IP65 provides "Dust-Tight" (level 6), while IP01 provides "No Protection" (level 0). IP65 is 6 levels higher.
Liquid protection
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP01
Level 1 — Vertically Dripping Water
IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP65 provides 4 levels more liquid protection.

Recommendation
IP65 offers higher overall protection than IP01. Choose IP65 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
