IP rating

Protection rating (degree of protection) – IP (Ingress Protection) rating of the devices, expressed as two digits, e.g. IP67. Each number denotes different degrees of protection against solid, dust and water ingress.

The first digit - solid or dust ingress protection.		The second digit - water ingress protection.
0	No protection.	0	No protection.
1	Protection against solid objects with a diameter greater than 50 mm.	1	Resistant to drops of water falling vertically.
2	Protection against solid objects with a diameter greater than 12.5 mm.	2	Resistant to drops falling at an angle of 15 degrees.
3	Protection against solid objects with a diameter greater than 2.5 mm.	3	Resistant to drops falling at an angle of 60 degrees.
4	Protection against solid objects with a diameter greater than 1 mm.	4	Protection against drops of water falling from all directions
5	Dust-resistance	5	Protection against streams of water from all directions.
6	Dust-proof	6	Powerful water jets (Hose diameter - 12.5 mm) (water pressure - 100 kPa)
		7	Device tight after submersion (for 30 minutes)
		8	Device tight with continuous submersion and increased pressure.
		9	Protection against streams of water from all directions. (applies to German standard DIN 40050)

A description for each digit is given below.

The first digit - solid or dust ingress protection.

0	No protection.	Not protected against solid and dust ingress.
1	Protection against solid objects with a diameter greater than 50 mm.	Protected against hand contact with live components.
2	Protection against solid objects with a diameter greater than 12.5 mm.	Protected against finger contact with live components.
3	Protection against solid objects with a diameter greater than 2.5 mm.	Protected against a tool, wire or solid object greater than 1 mm with live components.
4	Protection against solid objects with a diameter greater than 1 mm.	Protected against a tool, wire or solid object greater than 1 mm with live components.
5	Protection against substantial ingress of dust.	Protected against contact with live components. Dust protected. Limited ingress of dust permitted will not interfere with operation of the equipment or operation safety.
6	Protection against ingress of dust.	Protected against contact with live components.

The second digit - water ingress protection.

0	No protection.	No protection against water ingress.
1	Resistant to drops of water falling vertically.	Drops of water splashed on the device should not affect the operation safety.
2	Resistant to drops falling at an angle of 15 degrees.	Drops of water splashed on the device up to 15 degrees from vertical should not affect the operation safety.
3	Resistant to drops falling at an angle of 60 degrees.	Water splashed up to 60 degrees from the vertical from all directions should not affect the operation safety.
4	Protection against drops of water falling from all directions	Water splashed from all directions should not affect the operation safety.
5	Protection against streams of water from all directions.	Water jet from all directions should not affect the operation safety.
6	Protection against streams of water from all directions.	Water jet under pressure from all directions should not affect the operation safety. (Hose diameter - 12.5 mm) (water pressure - 100 kPa)
7	Device tight after submersion (for 30 minutes)	After immersing the device with its top surface at least 15 cm under the water surface, no water should ingress inside the device.
8	Device tight with continuous submersion and increased pressure.	After immersing the device for long period at a depth of at least 1 m, no water should ingress inside the device.
