IP16 vs IPX7
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP16 and IPX7 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 0) and liquid protection (level 6 vs 7). IP16 is rated for > 50 mm — back of hand and powerful water jets (12.5 mm nozzle), while IPX7 provides no protection and temporary immersion (up to 1 m).
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.
IPX7 resists temporary immersion up to 1 meter for 30 minutes, with solid protection not specified. Common for portable electronics that may be dropped in water.

The exact difference (IP16 vs IPX7)
Solid protection
IP16
Level 1 — > 50 mm — Back of Hand
IPX7
Level 0 — No Protection
IP16 provides "> 50 mm — Back of Hand" (level 1), while IPX7 provides "No Protection" (level 0). IP16 is 1 level higher.
Liquid protection
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IPX7
Level 7 — Temporary Immersion (up to 1 m)
IP16 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IPX7 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IPX7 provides 1 level more liquid protection.

Recommendation
IP16 and IPX7 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
