Protection classes of magnetic sensors

IP 65

1) Protection against penetration of dust and complete protection against contact with electrical components
2) Protection against a water jet from any direction.

IP 67

IP 67 comprises the IP 65 test specification and further enhanced water protection. The test piece must be immersed in water to a depth of 1 meter for 30 minutes.

IP 68

Water must not enter in a harmful quantity when the enclosure is immersed in water under defined conditions of pressure and time to be specified between manufacturer and user. The conditions however must exceed IP 67 requirements.

IP 69K

IP69K was initially developed for road vehicles, especially those needing regular intensive cleaning (dump trucks, cement mixers, etc.), but also finds use in other areas (e.g. food industry, car wash centres). IP 69K is an important standard for components deployed in road vehicles and the food and beverage industry. The test specification describes high-pressure cleaning with pure water at a pressure of 8'000 to 10'000 kPa and at a temperature of +80°C with a flow rate of 14 - 16 l/min for 30 seconds. Since the test specification differs substantially from those of other IPs, IP 69K protection does not automatically imply IP 67 or IP 68. IP 67 is the only standard to comprise also the lower degrees of protection.
