IP32 vs IP41
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP32 and IP41 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 4) and liquid protection (level 2 vs 1). IP32 is rated for > 2.5 mm — tool / wire and dripping water at 15° tilt, while IP41 provides > 1 mm — small wires and vertically dripping water.
Under IEC 60529, IP32 specifies protection against solid objects larger than 2.5 mm and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 2.
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 (IP32 vs IP41)
Solid protection
IP32
Level 3 — > 2.5 mm — Tool / Wire
IP41
Level 4 — > 1 mm — Small Wires
IP32 provides "> 2.5 mm — Tool / Wire" (level 3), while IP41 provides "> 1 mm — Small Wires" (level 4). IP41 is 1 level higher.
Liquid protection
IP32
Level 2 — Dripping Water at 15° Tilt
IP41
Level 1 — Vertically Dripping Water
IP32 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP41 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP32 provides 1 level more liquid protection.

Recommendation
IP32 and IP41 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
