The degrees of protection according to IEC60529 apply to various articles and provide information on protection against the intrusion of water and solids such as dust.
IP40Protects against contact with tools, wires and other similar objects of Ø > 1 mm and against the intrusion of foreign bodies of Ø > 1 mm. Does not protect against water.
IP65Fully protects against touch and against the intrusion of dust. Protects against sprayed water (jet) from any angle.
IP65 with cable diameter 6-7 mmFully protects against touch and against the intrusion of dust. Protects against sprayed water (jet) from any angle.
IP67Fully protects against touch and against the intrusion of dust. Protects against water intrusion in temporary immersion (depth: 1 m; duration: 30 minutes).
IP68/IP69K<u>IP68:</u> Fully protects against touch. Protects against the intrusion of dust. Protects against water intrusion in sustained immersion (depth: 2 m; duration: 24 hours), requirements specification by agreement between producer and user.<br/><br/><u>IP69K:</u> Fully protects against touch. Protects against the intrusion of dust. Protects against water intrusion under high pressure (8,000–10,000 kPa) from a jet or from steam-jet cleaning from any direction.
Connectors are differentiated by installation type: those that are mounted in a device housing (panel mount) and those that are attached to cables.
Cable mountingConnectors with cable already moulded or for self-assembly.
Housing assemblyConnectors that can be mounted to device housings. These can be fixed by means of a locking nut or be screwed in (requires a threaded hole).
Electromagnetic compatibility (EMC) means that a connector is shielded or shieldable. This is required when it is necessary to protect the signals or data conducted by the connector, as well as to protect external devices, from disturbance due to electromagnetic effects.
