IP11 vs IP26
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP11 and IP26 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 2) and liquid protection (level 1 vs 6). IP11 is rated for > 50 mm — back of hand and vertically dripping water, while IP26 provides > 12.5 mm — finger and powerful water jets (12.5 mm nozzle).
Engineered to deliver protection against solid objects larger than 50 mm and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP11, it pairs solid level 1 with liquid level 1.
Built to withstand protection against solid objects larger than 12.5 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.. Classified as IEC 60529 ingress protection code IP26, it pairs solid level 2 with liquid level 6.

The exact difference (IP11 vs IP26)
Solid protection
IP11
Level 1 — > 50 mm — Back of Hand
IP26
Level 2 — > 12.5 mm — Finger
IP11 provides "> 50 mm — Back of Hand" (level 1), while IP26 provides "> 12.5 mm — Finger" (level 2). IP26 is 1 level higher.
Liquid protection
IP11
Level 1 — Vertically Dripping Water
IP26
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP11 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP26 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP26 provides 5 levels more liquid protection.

Recommendation
IP26 offers higher overall protection than IP11. Choose IP26 for harsher environments; IP11 may suffice for milder conditions and can be more cost-effective.
