IP65, IP67 and IP69K devices


The IP rating (Ingress Protection) classifies the protection grade of electrical and electronic components to external factors such as particles, dust or water, according to the standard regulations (IEC60529: 2001) provided by the IEC (International Electro technical Commission).
The latest systems provided by DCM Sistemes offer IP65 grade protection as a standard feature. IP67 is also available as an optional feature. Both provide greater versatility as they can be used in environments with dirt, water, dust, shavings, etc.
Also, its exterior lines have been carefully and extremely designed. Systems have simple and smoothie forms, without holes or slots for easy cleaning and for accumulation of dirt preventing.
Our range of IP65/IP67 systems.
IEC 60529
The level protection of the system can be quickly and easily identified. You will find the level of protection in the system information included in our website.

- "IP" letters refer to the standard (Ingress Protection).
- The first digit describes the level of protection against solid objects and dust.
- The second numerical digit describes the level of protection against liquids (usually water).
Generally, we can say that with a higher IP level a better protection of the system is offered.
IP Rating Scale
The IEC 60529 standard requires that the system to be certified must meet one of the following conditions for each grade of protection:
Level | First digit (protection against solids) | Second digit (protection against liquids) |
---|---|---|
0 | No special protection. | No protection. |
1 | Protected against solid objects over 50 mm. | Protected against vertically falling drops of water in its normal use position at a rate of 1 liter/min for 10 minutes. |
2 | Protected against solid objects over 12,5 mm. | Protected against vertically falling drops of water in its normal use position or inclined up to 15º at a rate of 3 liters/min for 10 minutes. |
3 | Protected against solid objects over 2,5 mm. | Protected against water mist in its normal use position and with an angle projection of 60º maximum from the vertical at a pressure of 80-100 kPa and at a rate of 0,7litros/ min for 5 minutes. |
4 | Protected against solid objects over 1 mm. | Protected against water thrown from any angle at a pressure of 80-100 kPa and a rate of 10 liters/ min for 5 minutes. |
5 | Dust enters, but not an amount that interferes with the proper functioning of the system. | Protected against water jets thrown by a nozzle of 6.3mm of diameter from any angle at 3 meters of distance, at a pressure of 30 kPa and at a rate of 12.5 liters/ min for 5 minutes. |
6 | Dust must not enter under any circumstances. | Protected against powerful water jets thrown through a die of 12.5mm of diameter from any angle at 3 meters distance and a pressure of 100 kPa at a rate of 100 liters/min for 3 minutes. |
7 | ---- | The system must withstand without any filtering the complete immersion in water at a 1 meter distance for 30 minutes. |
8 | ---- | The system must withstand without any filtering the complete and continuous immersion in water taken into account the limits settled by the manufacturer if they are higher than the specified in grade 7. |
IP69K Specification
IP69K refers to the protection against water at high pressure and temperature specified by the German standard DIN 40050 Part9. Initially, it was developed for vehicle components that had to be cleaned regularly (as dump trucks, cement mixers, etc.) and it has been largely adopted by the food industry.
In industries such as food processing, where hygiene and cleanliness are important, the system should be able to withstand high pressure and temperature of washing and sanitizing processes.
The test consists of a spray nozzle with water at 80 °C of 80 to 100 bar and a flow rate of 14 to 16 liters/ min. The nozzle is located at 10 to 15 cm from the tested device in angles of 0 °, 40 °, 60 ° and 90 ° for 30 s each. The tested device is placed on a turntable.
Misconceptions in IP classification: it is common to have the misconception that IP69K grade protection automatically complies with IP67 and IP68. IP69K rated devices can withstand pressure and high temperature jet, surviving in wash-down environments such as breweries in car washing and food and beverage applications but, these devices may not be suitable in applications in which systems are immersed in water.
