How can I achieve an IP68 Rating with LEMO's K&E Environmentally sealed connectors?
LEMO publishes a rating of IP66/68 for LEMO K&E Series connectors.
There are 3 sealing points on a typical mated pair.
Seal between the plug and receptacle
Seal between the receptacle and the panel
Seal between the plug and the cable
IP68 is achieved for points 1 and 2. The connector to cable seal is highly dependant on the shape of the cable, therefore it can range from IP66 to IP68.
