IP11
Last updated: Aug 9, 2026Engineered 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.

What IP11 means
The IP code IP11 is part of the IEC 60529 standard for ingress protection. The first characteristic numeral, 1, indicates the level of protection against solid objects and access to hazardous parts. The second numeral, 1, indicates the level of protection against the ingress of water. Together, these digits describe exactly what an enclosure rated IP11 can withstand.
For solid protection, the digit 1 means the enclosure is > 50 mm — back of hand. Protected against access to hazardous parts with the back of a hand. Protected against solid foreign objects of 50 mm diameter and greater. The test method is access probe (50 mm sphere) shall not fully penetrate and shall have adequate clearance from hazardous parts.
For liquid protection, the digit 1 means the enclosure resists vertically dripping water. Protection against vertically falling drops of water. Dripping water shall have no harmful effects. The test procedure is drip box producing 1 mm/min rainfall; enclosure tested for 10 minutes in normal operating position.
IP11 vs IP12: the higher rating adds dripping water at 15° tilt. IP11 vs IP65: IP65 is dust-tight and water-jet resistant — a major upgrade for outdoor use. When specifying IP11 for a project, confirm the rating certificate from the manufacturer and consider that seals degrade over time with temperature cycling, UV exposure, and chemical contact.
