IP01 vs IP05
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP01 and IP05 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 1 vs 5). IP01 is rated for no protection and vertically dripping water, while IP05 provides no protection and water jets (6.3 mm nozzle).
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.
Under IEC 60529, IP05 specifies no protection against solid objects and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 5.

The exact difference (IP01 vs IP05)
Solid protection
IP01
Level 0 — No Protection
IP05
Level 0 — No Protection
Both IP01 and IP05 share the same solid protection: No Protection.
Liquid protection
IP01
Level 1 — Vertically Dripping Water
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP05 provides 4 levels more liquid protection.

Recommendation
IP05 offers higher overall protection than IP01. Choose IP05 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
