Brass
In most cases, LEMO connectors have a brass outer shell
which is suitable for most general purpose applications,
including civilian and military. The brass outer shells have
a chrome nickel-plated surface which ensures very good pro-
tection against industrial atmosphere, salt air and most cor-
rosive agents.
Alternative protective coatings are available to satisfy other
specific environmental conditions:
– electrolytic nickel
– nickel-gold
– nickel-black chrome. After the black chrome treatment, the
Plastic materials
Some connector model shells can be made of plastic. This
solution offers optimum electrical insulating properties par-
ticularly suitable for medical applications. Black Poly-
oxymethylene (POM) is particularly adapted to products of
the 00 or S series.
Grey or white polysulfone (PSU) and beige PEEK offers
excellent mechanical properties and is suitable for gas or vapour
sterilization.
Some models of the 2B and 3B series are available with an
outer shell of cream-coloured polyphenylsulfone (PPSU). We
recommend this material particularly for applications where
products are to withstand hundreds of vapour sterilization cycles.
part is coated with a protective organic film.
Bridge plug or plugs with parallel sockets are made of
Stainless steel
For applications where there are severe environmental con-
ditions that may rapidly damage the surface finish, we rec-
ommend using stainless steel. The AISI 303 stainless steel
is a material for general use adapted to most applications requir-
ing a product made entirely of stainless metal.
For the nuclear industry where elements are subject to radi-
ation and to vaporous nitric acid, we offer AISI 304 stainless
steel.
Grade AISI 316L is recommended for medical applications,
highly demanding with regard to non-corrosiveness. This mater-
ial is also used for connector shells soldered by electronic
beam onto a device made of the same stainless steel.
These parts have no surface treatment.
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 excel-
lent resistance to corrosion. The shell surface is protected
by anodizing which is available in six colours: blue, yellow,
black, red, green, and natural.

polyamide (PA.6) available in 9 colours: blue, white, grey,
yellow, brown, black, red, orange and green.
Some elbow socket shells for printed circuits are over-
moulded in polyphenilene sulfide (PPS).
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: earthing crown).
Depending on the application, these parts have electrolytic
nickel or nickel-gold plating.
These parts can also be manufactured in stainless steel.
Sealing gasket
In general, sealing gaskets are made of silicone rubber
MQ/MVQ. However, for vacuumtight sockets and couplers,
gaskets are made of fluorosilicone rubber (FPM).
Sealing resin
An epoxy resin is used to seal both watertight and vacuumtight
socket and coupler models.
