In this video, iCONN Systems test an assembly with IP67 specifications. The test aims to verify that the connector/cable assembly retains performance for 30 minutes, under 1M of water.
The product shown in this video is from the iMINI line, but all lines are rated to IP67. We had power running through the assembly to light the LED, showing there were no shorts caused by water. This demonstrates that water did not enter the assembly through the back of the overmold, meaning the overmold bonded to the cable jacket.
Many products requiring the IP67 rating are for applications where periodic water is present, including outdoor applications (rain) or applications that experience spills. Ensuring the IP67 rating means the cables and connectors are water resistant.DOWNLOAD ENGINEER'S GUIDE
