IP16 vs IP52
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP16 and IP52 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 5) and liquid protection (level 6 vs 2). IP16 is rated for > 50 mm — back of hand and powerful water jets (12.5 mm nozzle), while IP52 provides dust-protected and dripping water at 15° tilt.
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.
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) 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 5 with second-digit (liquid) level 2.

The exact difference (IP16 vs IP52)
Solid protection
IP16
Level 1 — > 50 mm — Back of Hand
IP52
Level 5 — Dust-Protected
IP16 provides "> 50 mm — Back of Hand" (level 1), while IP52 provides "Dust-Protected" (level 5). IP52 is 4 levels higher.
Liquid protection
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP52
Level 2 — Dripping Water at 15° Tilt
IP16 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP16 provides 4 levels more liquid protection.

Recommendation
IP16 and IP52 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
