Introduction This catalogue gives the complete description of LEMO connectors with coaxial, triaxial and hybrid contacts. Hybrid 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, available in contact configurations adapted to all round cables. The catalogue includes the B, K, S and E Series of the LEMO...

B Series B series connectors provide the following main features: – security of the Push-Pull self-latching system – coaxial, triaxial, multi and hybrid contact configurations – plastic models made of PSU or PPSU – multiple key options to avoid cross mating of similar connectors («G» key standard). – up to 10 coaxial contacts – solder or crimp contacts – high packing density for space savings – 360° screening for full EMC shielding Metal housing models Fixed plugs Straight plugs Fixed sockets Free sockets Elbow plugs Fixed sockets Plastic housing models Straight plugs Fixed sockets Model Description...

K Series K series connectors have been specifically designed for outdoor applications. They include an inner sleeve and two seals to prevent penetration of solids or liquids into the housing formed by the plug, free socket or fixed socket. All models (except FXl model) of this series are watertight when mated to give a protection index of IP68 as per IEC 60529 standard (in mated condition) when correctly assembled to an appropriate cable (IP66 otherwise). K series connectors have the same insulators as the B series and have the following main features: – security of the Push-Pull latching system...

00.650 Series The 00 Series are available in triax configuration, allowing a very compact solution for triaxial cables. These connectors are designed for small diameter ranging from 1.1 to 3.5 mm. Either twinax (2 shielded connectors) or triax (1 conductor and 2 concentric separate screens) can be used with the 00 Series. The 00 Series with a 650 configuration insert are mostly used in audio-video applications where a large density of connection is required. LEMO 00 Series connectors offer customers many benefits including: – self-latching push-pull system – ease of use – aesthetically pleasing...
