This catalogue gives the complete description of LEMO unipole and multipole type connectors. The LEMO manufacturing
programme has been extended to almost 40 series divided into 7 product families with specific mating and environmental
characteristics. Each series includes a wide variety of plug, socket, coupler and bridge plug models, available in contact
configurations adapted to all round cables, including up to 114 conductors, and a maximum diameter of 30 mm.
Watertight and vacuumtight models are also available. Since LEMO connectors are perfectly screened and designed to
guarantee very low resistance to shell electrical continuity, they are particularly adapted to applications where electro-
magnetic compatibility (EMC) is important.
