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
(not shown in this catalogue)
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.

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 coupling
system 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
Multipole Type (302, 303, 304, 306)
