K Connectors

LEMO K Connectors are specifically designed for outdoor applications with IP68 watertight connections when mated. These connectors feature an inner sleeve and two seals to prevent penetration of solids or liquids into the housing formed by the plug, free socket, fixed socket, or coupler. The push-pull latching mechanism provides a secure connection while multikey options prevent cross-mating of similar connectors within a panel. LEMO K Connectors offer rugged housing for extreme working conditions with more than 5000 mating cycles and a temperature range of -55°C to +200°C. These connectors are used in medical, audio, video, and energy industries.
