LEMO unipole and multipole connectors
This catalogue gives the complete description of LEMO unipole and multipole type connectors. The LEMO manu-
facturing 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 diam-
eter 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 electromagnetic compatibility (EMC) is important.
