IP05 vs IP41
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP41 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 5 vs 1). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP41 provides > 1 mm — small wires and vertically dripping water.
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.
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.

The exact difference (IP05 vs IP41)
Solid protection
IP05
Level 0 — No Protection
IP41
Level 4 — > 1 mm — Small Wires
IP05 provides "No Protection" (level 0), while IP41 provides "> 1 mm — Small Wires" (level 4). IP41 is 4 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP41
Level 1 — Vertically Dripping Water
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP41 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP05 provides 4 levels more liquid protection.

Recommendation
IP05 and IP41 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
