IP47 vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP47 and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 7 vs 1). IP47 is rated for > 1 mm — small wires and temporary immersion (up to 1 m), while IP61 provides dust-tight and vertically dripping water.
IP47 provides protection against solid objects larger than 1.0 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 7.
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 (IP47 vs IP61)
Solid protection
IP47
Level 4 — > 1 mm — Small Wires
IP61
Level 6 — Dust-Tight
IP47 provides "> 1 mm — Small Wires" (level 4), while IP61 provides "Dust-Tight" (level 6). IP61 is 2 levels higher.
Liquid protection
IP47
Level 7 — Temporary Immersion (up to 1 m)
IP61
Level 1 — Vertically Dripping Water
IP47 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP47 provides 6 levels more liquid protection.

Recommendation
IP47 offers higher overall protection than IP61. Choose IP47 for harsher environments; IP61 may suffice for milder conditions and can be more cost-effective.
