IP11 vs IP19K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP11 and IP19K are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 1 vs 9K). IP11 is rated for > 50 mm — back of hand and vertically dripping water, while IP19K provides > 50 mm — back of hand and high-pressure, high-temp water jets.
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.
Under IEC 60529, IP19K specifies protection against solid objects larger than 50 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 9K.

The exact difference (IP11 vs IP19K)
Solid protection
IP11
Level 1 — > 50 mm — Back of Hand
IP19K
Level 1 — > 50 mm — Back of Hand
Both IP11 and IP19K share the same solid protection: > 50 mm — Back of Hand.
Liquid protection
IP11
Level 1 — Vertically Dripping Water
IP19K
Level 9 — High-Pressure, High-Temp Water Jets
IP11 handles 0.1 mm/min drip rate (Vertically Dripping Water), while IP19K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP19K provides 8 levels more liquid protection.

Recommendation
IP19K offers higher overall protection than IP11. Choose IP19K for harsher environments; IP11 may suffice for milder conditions and can be more cost-effective.
