LEMO unipole and multipole connectors

Table of Contents

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 106 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 electro­magnetic compatibility (EMC) is important.

Precision modular connectors to suit your application

Since it’s creation in Switzerland in 1946 the LEMO Group has been recognized as a global leader of circular Push-Pull
connectors 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
handling cable diameters up to 30 mm and for up to 106 contacts.

This vast portfolio enables you to select the ideal connector configuration to suit almost any specific requirement in most
markets, 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
security 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
single axial pull on the outer release sleeve. This first
disengages 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 exceed 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
electronic equipment marketed in Europe.

3 steps to select the right connector

● Step 1: Select connector series

Select the appropriate LEMO connector series according to the environmental parameters that will affect your device
or cable such as indoor, outdoor, temperature range, ingress protection of the mated connector and of your device.
Use the table shown on page 4.

Part number coding

● Step 2: Select connector size

.

..

B, K, S, E, L, G, C or D

Use the section (mm2) or the AWG of your cable wire to select the optimal contact diameter (values vary between
solder, crimp or print contact), see page 7.

Use this optimal contact diameter to determine the right connector size as well as the insert configuration, see page 6.

Part number coding

Step 3: Complete the part number

●

.. .

0, 1, 2, 3, 4, 5 or 6

Now that you know the series, as well as the insulator configuration, complete the part numbering system with the help
of the following table.

Step 1: Select Connector Series

LEMO unipole and multipole connectors

The standard keyed Series (B, 00, G)

The characteristic feature of these connector series is a keying system which allows higher contact density and prevents
all errors in alignment. The various keying alternatives prevent unwanted cross mating of otherwise similar connectors. It
is also possible to use crimp contacts to reduce cable assembly time. These connector series, include the 0B to 5B range
as well as the 00 multipole and 2G (shortened version of the 2B series), some vacuumtight models are also available.

The watertight keyed Series (K, L)
These series are watertight when mated and assembled to an appropriate cable. They include the 0K to 5K series, avail­able in the same types as the 0B to 5B series, and the 0L to 2L series with keying and hermaphroditic insulator.

The standard Series (S, 00, C, D)
The characteristic feature of these connector series is the hermaphroditic insulator in the multipole version. They include
principally the 0S to 6S series, as well as the 00 unipole series, the 2C (shortened version) and the 1D quadrax type
(with 4 concentric contacts).

The watertight Series (E)
These series are watertight when mated and assembled to an appropriate cable. They include the 0E to 6E series and
are available in the same types as the S series.

Second digit description

Selection of connectors for watertight or vacuumtight devices

LEMO B and S series are rated IP50 only when mated. LEMO E, K and L series are rated IP66 (and over) only when
mated. If a device must be watertight or vacuumtight when the connectors are unmated, it is important to select a watertight
or vacuumtight socket. You can consider the following two situations:

A) Figure 1 shows a typical outdoor device. To ensure this

device retains IP66 or above when connectors are
unmated, it is important to choose a watertight socket
from B, S, E, K or L series.

Check temperature range (see section on pages 26, 41, 72, 82 and 89).

B) Figure 2 shows a device which is subjected to pressure

difference such as a near vacuum or pressurized gas
and must exhibit no leakage. To ensure the device
maintains its sealing, the socket is additionally tested for
helium leakage (according MIL 1344A).

Step 2: Select Connector Size

Select the right connector size and insert configuration

To be able to select the right connector size (0 to 6), it is important to define the contact diameter (ø A).
Find out the available contact diameter (ø A) of the LEMO connector depending on the number of contacts required and
depending on the rating required (see pages 45 to 49 and 91 to 98).
The following table shows the contact diameter (ø A), or the solder pot diameter (ø C) for the 1D series.

Watertight or vacuumtight models

These plug, socket and coupler models allow the device on which they are fitted to reach a protection index of IP68 as per
IEC 60529. They are fully compatible with plugs of the same series and are widely used for portable radios, military, labo­ratory equipment, aviation, etc.
These models are identified by a letter «P» at the end of the reference.
Most of these models are also available in a vacuumtight version. Such models are identified by an additional letter «V» at
the end of the part number (certificate on request).
Epoxy resin is used to seal these models.

free socket, fixed socket or coupler. 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)
– multipole types 2 to 64 contacts – solder, crimp or print (straight or elbow) contacts
– keying system («G» key standard) – multiple key options to avoid cross mating

for connector alignment of similar connectors
– 360° screening for full EMC shielding – high packing density for space savings
– rugged housing for extreme working conditions.

Soldering characteristics

– no need to order specific tools, a simple soldering iron is

sufficient
– ideal for very small and fragile conductors
– contacts with solder cups to allow the solder to flow

Note: see page 176 for more information.

Contacts (B and K series)

Crimping characteristics

– practical, quick contact fixing outside the insulator
– possible use at high temperature
– need to order specific tools
– no risk of heating the insulator during the conductor-

contact fixing
– high tensile strength
– totally lead-free solution

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, fixed socket or coupler. 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 – watertight connection (IP 68/IP 66)
– unipole types transmitting current up to 230 A – polarization by stepped insert (half-moon)

and multipole types with up to 106 contacts fitted with male and female contacts
– wide range of models satisfying most applications – solder or print contacts (straight or elbow)
– 360° screening for full EMC shielding – rugged housing for extreme working condition.

Watertight or vacuumtight models

These socket or coupler models allow the device on which they are fitted to reach a protection index of IP 68 as per IEC 60529.
They are fully compatible with plugs of the same series and are widely used for portable radios, military, laboratory equip­ment, aviation, etc.
These models are identified by a letter «P» at the end of the reference.
Most of these models are also available in a vacuumtight version. Such models are identified by an additional letter «V» at
the end of the part number (certificate on request).
Epoxy resin is used to seal these models.

L Series

L series connectors have been specifically designed for outdoor applications. This series offer superior polarization combining
the stepped insert (half-moon) of the S/E series with the keying system of the K series.
They include an inner sleeve and two seals to prevent penetration of solids or liquids into the housing formed by the plug,
free socket, fixed socket or coupler. 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).
L series connectors have the same insulators as the S series and have the following main features:
– security of the Push-Pull latching system – watertight connection (IP 68/IP 66)
– multipole types 2 to 10 contacts – solder, crimp or print (straight) contacts
– stepped insert (half-moon) fitted – multiple key options to avoid cross mating

with male and female contacts of similar connectors
– high packing density for space savings – 360° screening for full EMC shielding
– keying system («G» key standard) for connector alignment – rugged housing for extreme working conditions.
