IP25 vs IP6X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IP6X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 6) and liquid protection (level 5 vs 0). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IP6X provides dust-tight and no protection.
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 mm and protection against water jets. Water projected by a 6.3 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 2 with second-digit (liquid) level 5.
IP6X is fully dust-tight—no ingress of dust whatsoever—with water protection not specified. The highest solid-protection rating, used where complete dust exclusion is critical.

The exact difference (IP25 vs IP6X)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IP6X
Level 6 — Dust-Tight
IP25 provides "> 12.5 mm — Finger" (level 2), while IP6X provides "Dust-Tight" (level 6). IP6X is 4 levels higher.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP6X
Level 0 — No Protection
IP25 provides "Water Jets (6.3 mm nozzle)" (level 5), while IP6X provides "No Protection" (level 0). IP25 is 5 levels higher.

Recommendation
IP25 offers higher overall protection than IP6X. Choose IP25 for harsher environments; IP6X may suffice for milder conditions and can be more cost-effective.
