IP36 vs IP61
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP36 and IP61 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 6) and liquid protection (level 6 vs 1). IP36 is rated for > 2.5 mm — tool / wire and powerful water jets (12.5 mm nozzle), while IP61 provides dust-tight and vertically dripping water.
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.
IP61 is an ingress protection code that ensures dust-tight (no ingress of dust) and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 6 with second-digit (liquid) level 1.

The exact difference (IP36 vs IP61)
Solid protection
IP36
Level 3 — > 2.5 mm — Tool / Wire
IP61
Level 6 — Dust-Tight
IP36 provides "> 2.5 mm — Tool / Wire" (level 3), while IP61 provides "Dust-Tight" (level 6). IP61 is 3 levels higher.
Liquid protection
IP36
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP61
Level 1 — Vertically Dripping Water
IP36 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP61 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP36 provides 5 levels more liquid protection.

Recommendation
IP36 offers higher overall protection than IP61. Choose IP36 for harsher environments; IP61 may suffice for milder conditions and can be more cost-effective.
