Waterproof Design

Understanding the IP rating system

The IP Code, or Ingress Protection rating, is used to specify the degree of protection against the intrusion of solid objects and liquids in electrical enclosures.

The first number refers to solid materials penetration like dust, sand, but also fingers and other solid objects. The second number refers to the level of protection against liquid intrusion.

For example, a product rated IP67 will be completely dust-tight and watertight under 1m of water for 30 minutes.

50 mm or more

Protected against solid foreign objects of 50 mm and greater. Shall not fully penetrate.

Vertically falling drops

Protected against vertically falling water drops. Shall have no harmful effects.

12.5 mm or more

Protected against solid foreign objects of 12.5 mm and greater. Shall not fully penetrate.

15° falling drops

Protected against 15° falling drops. Shall have no harmful effects.

2.5 mm or more

Protected against solid foreign objects of 2.5 mm and greater. Shall not penetrate at all.

Water sprayed at 60°

Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.

1 mm or more

Protected against solid foreign objects of 1.0 mm and greater. Shall not penetrate at all.

Water splashed against the enclosure

Water splashed against the enclosure from any direction shall have no harmful effects.

Dust protected

Ingress of dust not totally prevented, but dust shall not interfere with operation.

Water projected in jets

Water projected in jets against the enclosure from any direction shall have no harmful effects.

Dust-tight

No ingress of dust.

Water projected in powerful jets

Water projected in powerful jets against the enclosure from any direction shall have no harmful effects.

Temporary immersion in water

Protected against the effects of temporary immersion in 1 meter of water. No ingress.

Continuous immersion in water

Protected against the effects of continuous immersion in more than 1 meter of water. No ingress.
