IP68 is immersion under stated conditions. IPX9K is hot, high-pressure water jets. Why a wash-down application needs both.

Short answers on current rating, sealing, termination, temperature range, mating cycles, CAD files and samples.

Planned topics include current rating and temperature rise, panel sealing, and cable selection. They will be published with approved test data.
