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-Pullconnectors and connector solutions. Today LEMO and its affiliated companies, REDEL and COELVER, are active in morethan 80 countries with the help of over 40 subsidiaries and distributors.

Over 75000 connectors
The modular design of the LEMO range provides over 75000 connectors from miniature ø 3 mm to ø 50 mm, capable ofhandling 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 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 bypulling on the cable or any other component part otherthan the outer release sleeve.

When required, the connector is disengaged by asingle 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 orseveral European safety directives. CE marking
applies to complete products or equipment, but not to electromechanical 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 andelectronic equipment marketed in Europe.

Product safety notice & disclaimers
Please read and follow all instructions specified on the last page or on our website carefully and consult all relevent
national and international safety regulations for your application. Improper handling, cable assembly, or wrong use ofconnectors can result in hazardous situations.
LEMO products and services are provided “as is.” LEMO makes no warranties or representations with regard to LEMO
product & services or use of them, express, implied or statutory, including for accuracy, completeness, or security.
In no event shall LEMO be liable for any direct, indirect, punitive, incidental, special consequential damages, to property
or life, whatsoever arising out of or connected with the use or misuse of LEMO’s products.

03 Series
This series of connectors stems from the series 00 and has been specifically developed for applications where the connection
must be guaranteed under very high pressure. The push-pull latching system has been replaced by a screw couplingsystem with watertightness maintained by compression of an O-ring in FPM (Viton®) according to the triangular shaped
cavity principle. There are multiple application possibilities, from aerospace to the petroleum industry.
After cable assembly, the rear part must be covered with an adhesive heatshrink boot in order to ensure watertightness
on the cable side. 03 series connectors provide the following main features:– coaxial 50 Ω type– multipole with 2, 3, 4 or 6 contacts– 360° screening for full EMC shielding– rugged housing for extreme working conditions– working pressure that can exceed 60 bars in mated conditions

Vacuumtight models (multipole type)
These sockets 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» or «S» at the last but one character of the reference. The Stycast® sealant canbe used over a larger temperature range than the Araldite® sealant.
Vaccumtight 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.

Cable assembly
Assembly instructions
In order to ensure the sealing of plugs and sockets on the cable side, it is imperatively necessary to complete their assemblyby realizing it with an adapted technique.
We recommend the fitting of an heatshrink boot with inner melting coating of type ATUM (manufactured by the RAYCHEM
company) or similar.
This heatshrink boot is not provided with the connector. Please consult us.

Product safety notice
PLEASE READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY AND CONSULT ALL RELEVENT NATIONAL AND
INTERNATIONAL SAFETY REGULATIONS FOR YOUR APPLICATION.
IMPROPER HANDLING, CABLE ASSEMBLY, OR WRONG USE OF CONNECTORS CAN RESULT IN HAZARDOUS
SITUATIONS.
1. SHOCK AND FIRE HAZARD
Incorrect wiring, the use of damaged components, presence of foreign objects (such as metal debris), and / or residue(such as cleaning fluids), can result in short circuits, overheating, and / or risk of electric shock.
Mated components should never be disconnected while live as this may result in an exposed electric arc and local
overheating, resulting in possible damage to components.
2. HANDLING
Connectors and their components should be visually inspected for damage prior to installation and assembly. Suspectcomponents should be rejected or returned to the factory for verification.
Connector assembly and installation should only be carried out by properly trained personnel. Proper tools must be usedduring installation and / or assembly in order to obtain safe and reliable performance.
3. USE
Connectors with exposed contacts should never be live (or on the current supply side of a circuit). Under generalconditions voltages above 30 VAC and 42 VDC are considered hazardous and proper measures should be taken toeliminate all risk of transmission of such voltages to any exposed metal part of the connector.
4. TEST AND OPERATING VOLTAGESThe maximum admissible operating voltage depends upon the national or international standards in force for theapplication in question. Air and creepage distances impact the operating voltage; reference values are indicated in the
catalogue however these may be influenced by PC board design and / or wiring harnesses.
The test voltage indicated in the catalogue is 75% of the mean breakdown voltage; the test is applied at 500 V/s and thetest duration is 1 minute.
5. CE MARKING
CE marking
means that the appliance or equipment bearing it complies with the protection requirements of one orseveral European safety directives.
CE marking
applies to complete products or equipment, but not to electromechanical components, such as
connectors.
6. PRODUCT IMPROVEMENTS
The LEMO Group reserves the right to modify and improve to our products or specifications without providing priornotification.
