The Industrial Ethernet connector family was designed specifically for challenging environments, such as sub zero cold or extreme heat. Typically, an IP67 rating means that the connector can be ‘splashed’ or ‘rained on’. The official test involves pressurizing a mated pair to 1.5 psi for 30 minutes, with no water leakage observed. In practice, these connectors withstand most common industrial liquids they might come in contact with.
