IP01 vs IP23
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP01 and IP23 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 1 vs 3). IP01 is rated for no protection and vertically dripping water, while IP23 provides > 12.5 mm — finger and spraying water (up to 60°).
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, IP23 specifies protection against solid objects larger than 12.5 mm and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 3.

The exact difference (IP01 vs IP23)
Solid protection
IP01
Level 0 — No Protection
IP23
Level 2 — > 12.5 mm — Finger
IP01 provides "No Protection" (level 0), while IP23 provides "> 12.5 mm — Finger" (level 2). IP23 is 2 levels higher.
Liquid protection
IP01
Level 1 — Vertically Dripping Water
IP23
Level 3 — Spraying Water (up to 60°)
IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP23 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP23 provides 2 levels more liquid protection.

Recommendation
IP23 offers higher overall protection than IP01. Choose IP23 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
