What is the IP Rating of heavy-duty connectors?
IP ratings, also called Ingress Protection rating. IP rating is the degree of protection against the intrusion of foreign objects into the enclosure of electrical equipment. The source is the standard IEC 60529 of the International Electrotechnical Commission.
Heavy Duty Connector IP Class
From the first time, the heavy-duty connectors are designed with high-level IP ratings.
The connector’s housing, sealing, and locking mechanism protect the connection from external influences such as mechanical shocks, foreign bodies, humidity, dust, water, or other fluids such as cleansing and cooling agents, oils, etc. The degree of protection the housing offers is explained in the IEC 60 529, DIN EN 60 529, standards that categorize enclosures according to foreign body and water protection.
The following table shows the different degrees of protection.
Usually, there are IP65, IP68, and IP69K for heavy-duty connector designs according to different application conditions. You can see in the charts below shows all the IP ratings for heavy duty connectors which is presented by harting connectors.
So when choosing heavy-duty connectors for your device, you need to consider the IP ratings. Normally, for heavy-duty connectors or rectangular connectors, suppliers usually provide IP65, IP68, or IP69K; these 3 options to select, which can meet the overall application working device requirements.
