The IP65 standard according to DIN defines the degree of protection of electrical devices, in particular cable connectors and chassis sockets, against the ingress of foreign bodies and moisture. Here is a detailed description:
IP: As already mentioned, this stands for "Ingress Protection" or "International Protection".
6: The first digit indicates the degree of protection against the ingress of foreign bodies. A "6" means that the device is completely dustproof. It therefore offers the highest level of protection against the ingress of dust particles.
5: The second digit indicates the degree of protection against moisture. A "5" means that the device is protected against water jets from any angle. It can therefore withstand strong water jets, but not immersion in water.
Cable connectors and chassis sockets manufactured to the IP65 standard are therefore suitable for applications where they are exposed to strong water jets, such as in outdoor areas, on ships, in industry or in other environments where moisture and cleaning may play a role.
These devices are often found in areas where a reliable electrical connection must be guaranteed under demanding conditions, such as in the machine industry, outdoor events, the maritime industry or in food processing.
