Precision modular connectors to suit your application
Since its creation in Switzerland in 1946 the LEMO Group has been recognized as a global leader of circular Push-Pull con-
nectors and connector solutions. Today LEMO and its affiliated companies, REDEL and COELVER, are active in more than
80 countries with the help of over 40 subsidiaries and distributors.
Over 75’000 connectors
The modular design of the LEMO range provides over 75’000 connectors from miniature ø 3 mm to ø 50 mm, capable of han-
dling cable diameters up to 30 mm and for up to 114 contacts.
This vast portfolio enables you to select the ideal connector configuration to suit almost any specific requirement in most mar-
kets, including medical devices, test and measurement instruments, machinery, audio video broadcast, telecommunications
and military.
LEMO’s Push-Pull Self-Latching Connection System
This self-latching system is renowned worldwide for its easy and quick mating and unmating features. It provides absolute secu-
rity against vibration, shock or pull on the cable, and facilitates operation in a very limited space.
The LEMO self-latching system allows the connector
to be mated by simply pushing the plug axially into the
socket.
Once firmly latched, connection cannot be broken by
pulling on the cable or any other component part other
than the outer release sleeve.
When required, the connector is disengaged by a sin-
gle axial pull on the outer release sleeve. This first dis-
engages the latches and then withdraws the plug from
the socket.
UL Recognition
LEMO connectors are recognized by the Underwriters Laboratories (UL). The approval of the complete system (LEMO
connector, cable and your equipment) will be easier because LEMO connectors are recognized.
CE marking
CE marking means that the appliance or equipment bearing it complies with the protection requirements of one or
several European safety directives. CE marking applies to complete products or equipment, but not to electrome-
chanical components, such as connectors.
RoHS
LEMO connector specifications conforms the requirements of the RoHS directive (2011/65/EU) of the European Parliament
and the latest amendments. This directive specifies the restrictions of the use of hazardous substances in electrical and elec-
tronic equipment marketed in Europe.

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.

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

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 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 – watertight connection (IP 68/IP 66)
– coaxial, triaxial and mixed contact configurations – up to 10 coaxial contacts
– solder or crimp contacts – 360° screening for full EMC shielding
– multiple key options to avoid cross mating – high packing density for space savings
of similar connectors («G» key standard) – rugged housing for extreme working conditions.

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 appearance – low weight
– small size – reliable performances
– high packing density – wide choice to suit application
– rugged construction.

E Series
E 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 of these series are watertight when mated and give a protection index of IP 68 as
per IEC 60529 standard (in mated condition) when correctly assembled to an appropriate cable (IP 66 otherwise).
– security of the Push-Pull latching system – coaxial, triaxial and mixed contact configurations
– watertight connection (IP 68/IP 66) – polarization by stepped insert (half-moon)
– solder contacts, print contacts only – 360° screening for full EMC shielding
for coaxial and triaxial configurations – rugged housing for extreme working condition.
