IP25 vs IP5X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IP5X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 5) and liquid protection (level 5 vs 0). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IP5X provides dust-protected 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.
IP5X is dust-protected (limited ingress, no harmful deposit) with water protection not specified. Used where dust limitation matters but the equipment is kept dry.

The exact difference (IP25 vs IP5X)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IP5X
Level 5 — Dust-Protected
IP25 provides "> 12.5 mm — Finger" (level 2), while IP5X provides "Dust-Protected" (level 5). IP5X is 3 levels higher.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP5X
Level 0 — No Protection
IP25 provides "Water Jets (6.3 mm nozzle)" (level 5), while IP5X provides "No Protection" (level 0). IP25 is 5 levels higher.

Recommendation
IP25 offers higher overall protection than IP5X. Choose IP25 for harsher environments; IP5X may suffice for milder conditions and can be more cost-effective.
