LEMO unipole and multipole connectors 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 114 conductors, and a maximum diameter of 30 mm. Watertight and vacuumtight models are also available. Since LEMO connectors are perfectly screened...

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 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 90000 connectors The modular design of the LEMO range provides over 90000 connectors from miniature ø 3 mm to ø 50 mm, capable of handling cable diameters up to 30 mm and for up to 114 contacts. This vast portfolio enables you to select...

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 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 8. Use this optimal contact diameter to determine the right connector...

Step 1: Select Connector Series LEMO unipole and multipole connectors The standard keyed Series (B, 00) 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, some vacuumtight models are also available. The watertight keyed Series (K, T) These series are watertight...

Definition of Ingress Protection (IP code) IEC 60529 outlines an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, fingers) and moisture. This classification system utilizes the letters «IP» (Ingress Protection) followed by two digits. Degrees of protection - First digit The first digit of the IP code indicates the degree to which persons are protected against contact with moving parts and the degree that equipment is protected against solid foreign bodies intruding...

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 57 to 63 and 103 to 111). The following table shows the contact diameter (ø A). Insert configuration

Note: 1) 2.0 is for 6S series, for 6E the values are 1.3 and 5.0. Insert configuration

Verify the fitting to your wire Verify if the selected contact diameter (ø A) of the LEMO connector fits to your cable wire diameter (AWG number or max. available section). Contact type Conductor Stranded AWG Section (mm2) Note: 1) contact retention force in the insulator (according to IEC 60512-8 test 15 a). 2) for 00/TT multipole series. 3) for S, E series. 4) for a given AWG, the diameter of some stranded conductor designs is larger than the solder cup diameter. Make sure that the maximum conductor diameter is smaller than ø C. 5) for 00 /TT multipole series or for 0B/0T and 1B/1T series with...
