IP16 vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP16 and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 6) and liquid protection (level 6 vs 1). IP16 is rated for > 50 mm — back of hand and powerful water jets (12.5 mm nozzle), while IP61 provides dust-tight and vertically dripping water.
IP16 is an ingress protection code that ensures protection against solid objects larger than 50 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 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 1 with second-digit (liquid) level 6.
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 (IP16 vs IP61)
Solid protection
IP16
Level 1 — > 50 mm — Back of Hand
IP61
Level 6 — Dust-Tight
IP16 provides "> 50 mm — Back of Hand" (level 1), while IP61 provides "Dust-Tight" (level 6). IP61 is 5 levels higher.
Liquid protection
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP61
Level 1 — Vertically Dripping Water
IP16 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP16 provides 5 levels more liquid protection.

Recommendation
IP16 and IP61 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
