IP36 vs IP5X
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP36 and IP5X are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 5) and liquid protection (level 6 vs 0). IP36 is rated for > 2.5 mm — tool / wire and powerful water jets (12.5 mm nozzle), while IP5X provides dust-protected and no protection.
The IP36 classification guarantees protection against solid objects larger than 2.5 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 3 with second-digit (liquid) level 6.
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 (IP36 vs IP5X)
Solid protection
IP36
Level 3 — > 2.5 mm — Tool / Wire
IP5X
Level 5 — Dust-Protected
IP36 provides "> 2.5 mm — Tool / Wire" (level 3), while IP5X provides "Dust-Protected" (level 5). IP5X is 2 levels higher.
Liquid protection
IP36
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP5X
Level 0 — No Protection
IP36 provides "Powerful Water Jets (12.5 mm nozzle)" (level 6), while IP5X provides "No Protection" (level 0). IP36 is 6 levels higher.

Recommendation
IP36 offers higher overall protection than IP5X. Choose IP36 for harsher environments; IP5X may suffice for milder conditions and can be more cost-effective.
