IP35 vs IP5X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP35 and IP5X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 5) and liquid protection (level 5 vs 0). IP35 is rated for > 2.5 mm — tool / wire and water jets (6.3 mm nozzle), while IP5X provides dust-protected and no protection.
Built to withstand protection against solid objects larger than 2.5 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.. Classified as IEC 60529 ingress protection code IP35, it pairs solid level 3 with 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 (IP35 vs IP5X)
Solid protection
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP5X
Level 5 — Dust-Protected
IP35 provides "> 2.5 mm — Tool / Wire" (level 3), while IP5X provides "Dust-Protected" (level 5). IP5X is 2 levels higher.
Liquid protection
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IP5X
Level 0 — No Protection
IP35 provides "Water Jets (6.3 mm nozzle)" (level 5), while IP5X provides "No Protection" (level 0). IP35 is 5 levels higher.

Recommendation
IP35 offers higher overall protection than IP5X. Choose IP35 for harsher environments; IP5X may suffice for milder conditions and can be more cost-effective.
