What is Waterproof IP65?

The IP Code, or Ingress Protection CodeIEC standard 60529, sometimes interpreted as International Protection Code, classifies and rates the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water...

What do the two digits in an IP Rating mean?

The rating consists of the letters IP followed by two digits, the higher the number the better the protection.  Sometimes a number is replaced by X, which indicates that the enclosure is not rated for that specification. 

IP65   =  First Digit - Solids

The first digit indicates the level of protection that the enclosure provides against the ingress of solid foreign objects, from tools or fingers that could be hazardous if they came into contact with electrical conductors or moving parts, to airborne dirt and dust that could damage circuitry.

IP65   =  Second Digit - Liquids

The second digit defines the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion etc).

First Digit Intrusion Protection Second Digit Moisture Protection
0 No protection. 0 No protection.
1 Protected against solid objects over 50mm, e.g. accidental touch by hands. 1 Protected against vertically falling drops of water, e.g. condensation.
2 Protected against solid objects over 12mm, e.g. fingers. 2 Protected against direct sprays of water up to 150 from the vertical.
3 Protected against solid objects over 2.5mm, e.g. tools & wires. 3 Protected against direct sprays of water up to 600 from the vertical.
4 Protected against solid objects over 1mm, e.g. wires & nails. 4 Protected against water splashed from all directions, limited ingress permitted.
5 Protected against dust limited ingress, no harmful deposits. 5 Protected against low pressure jets of water from all directions, limited ingress permitted.
6 Totally protected against dust. 6 Protected against strong jets of water, e.g. on ships deck, limited ingress permitted.
