Technical characteristics
Outer shell
Brass
In most cases, LEMO connectors have a brass outer
shell which is suitable for most general purpose applica-
tions, including civilian and military. The brass outer
shells have a chrome nickel-plated surface which
ensures very good protection against industrial atmos-
phere, salt air and most corrosive agents.
Alternative protective coatings are available to satisfy
other specific environmental conditions:
– electrolytic nickel
– nickel-black chrome. After the black chrome treatment,
Stainless steel
For applications where there are severe environmental
conditions that may rapidly damage the surface finish, we
recommend using stainless steel. The AISI 303 stainless
steel is a material for general use adapted to most appli-
cations requiring a product made entirely of stainless
metal.
For the broadcasting industry the heavy duty line with
shell in stainless steel offers more resistance to heavy
wear conditions.
Aluminium alloy
The aluminium alloy outer shells find numerous applica-
tions where light weight is a predominant factor, such as
in the aeronautics and space industries, and for portable
and mobile equipment.
These materials have high mechanical strength and
excellent resistance to corrosion.

The shell surface is protected by anodizing which is avai-
lable in six colours: blue, yellow, black, red, green, and
natural.
Depending on the application, other surface finish is also
available (electrolytic nickel-plating, black nickel plating).
Plastic materials
Some connector model shells of the 2B-4B series can be
made of plastic. This solution offers optimum electrical
insulating properties particularly suitable for medical
applications.
Grey or white polysulfone (PSU) and beige PEEK offer
excellent mechanical properties and is suitable for gas or
vapour sterilization.
Some models are also available with an outer shell of
cream-coloured polyphenylsulfone (PPSU). We recom-
mend this material particularly for applications where pro-
ducts are to withstand hundreds of vapour sterilization
cycles.
Other metallic components
In general, most metallic components are manufactured
in brass. However, bronze or beryllium copper are used
where good elasticity is required (for example: grounding
crown). Depending on the application, these parts have
electrolytic nickel or nickel-gold plating. These parts can
also be manufactured in stainless steel (AISI 416).
Gasket and O-rings
In general, gaskets and O-rings are made of silicone
rubber MQ/MVQ. However, for some products they are
made of fluorosilicone rubber (FPM).
