LEMO coaxial 00 and 01 Series ( 50
Ω
)
Fundamental research in particle physics as practised within CERN and other nuclear research establishments requires
more and more complex equipment of high performance in order to achieve the objectives. The needs of such research
contribute to the development of leading products for the whole of industry. For many years LEMO has participated in
this evolution. This has resulted in a range of miniature coaxial connectors (50
Ω)
with a push-pull self-latching system,
the LEMO 00.250 series. These connectors now form the basis of the NIM-CAMAC CD/N 549 standard.
The plugs and sockets of the 01 series are amongst the smallest available 50
Ω
coaxial connectors with a self-latching
intermating capability. In spite of their small size and light weight, their technical characteristics remain excellent. Avail-
able in a wide range of housing configurations, they are especially useful when connecting onto printed circuit boards.
The LEMO 00 series and 01 are now used in many areas such as : telecommunications, sensors, medical equipment,
space research, etc...
The program covered in this catalog now includes more than 50 models suitable for many cable types.

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 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

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 conforms the requirements of the RoHS directive (2011/65/EU) of the European Parlia-
ment and the latest amendments. This directive specifies the restrictions of the use of hazardous substances in electrical
and electronic equipment marketed in Europe.

2 steps to select the right connector
●
Step 1: Select connector series
Select the appropriate LEMO connector series according to the standard, the cable, according to the application or
the mated connector already on your equipment.

00 or 01 series
The NIM-CAMAC 00 .250 series
The 00 series is coaxial (50
Ω
). This connectors family was conceived for all applications where a high density of
connectors is necessary, especially for patch panels. Because of LEMO’s special self-latching system, it is possible
to connect them with a simple axial push-pull thereby reducing the space needed to mount sockets to an absolute
minimum, up to 50 sockets per square decimetre. LEMO 00 connectors served as the norm for NIM-CAMAC
CD/N549 standard, used in nuclear physics as well as many other applications.
The miniature 01.250 series
The 01 series is coaxial (50
Ω
). The plugs and sockets are amongst the smallest available 50
Ω
coax connectors with a
self-latching intermating capability. In spite of their small size and light weight, their technical characteristics remain
excellent. Available in a wide range of housing configurations, they are especially useful when connecting onto printed
circuit boards.
