Introduction
This catalogue gives the complete description of LEMO connectors with coaxial, triaxial and mixed contacts.
Mixed contacts include coaxial and low voltage contact configurations, as well as multi-coaxial contact configurations.
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 and coupler models, avail-
able in contact configurations adapted to all round cables. The catalogue includes the B, K, S and E Series of the LEMO
product range. In addition the 00 Series (triaxial) connector is also represented.
Watertight and vacuumtight models are also available. Since LEMO connectors are perfectly screened and designed to guar-
antee very low resistance to shell electrical continuity, they are particularly adapted to applications where electromagnetic
compatibility (EMC) is important.
