IP12 vs IP47
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP12 and IP47 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 4) and liquid protection (level 2 vs 7). IP12 is rated for > 50 mm — back of hand and dripping water at 15° tilt, while IP47 provides > 1 mm — small wires and temporary immersion (up to 1 m).
Designed for environments requiring protection against solid objects larger than 50 mm and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position., IP12 is an IEC 60529 code combining solid level 1 with liquid level 2.
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.

The exact difference (IP12 vs IP47)
Solid protection
IP12
Level 1 — > 50 mm — Back of Hand
IP47
Level 4 — > 1 mm — Small Wires
IP12 provides "> 50 mm — Back of Hand" (level 1), while IP47 provides "> 1 mm — Small Wires" (level 4). IP47 is 3 levels higher.
Liquid protection
IP12
Level 2 — Dripping Water at 15° Tilt
IP47
Level 7 — Temporary Immersion (up to 1 m)
IP12 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP47 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP47 provides 5 levels more liquid protection.

Recommendation
IP47 offers higher overall protection than IP12. Choose IP47 for harsher environments; IP12 may suffice for milder conditions and can be more cost-effective.
