IP25 vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6) and liquid protection (level 5 vs 1). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IP61 provides dust-tight and vertically dripping water.
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 mm 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 2 with second-digit (liquid) level 5.
IP61 is an ingress protection code that ensures dust-tight (no ingress of dust) 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 6 with second-digit (liquid) level 1.

The exact difference (IP25 vs IP61)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IP61
Level 6 — Dust-Tight
IP25 provides "> 12.5 mm — Finger" (level 2), while IP61 provides "Dust-Tight" (level 6). IP61 is 4 levels higher.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP61
Level 1 — Vertically Dripping Water
IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP25 provides 4 levels more liquid protection.

Recommendation
IP25 and IP61 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
