Outer Shell
Brass
LEMO series 00 & 01 connectors have a brass outer
shell as standard, and this is suitable for most general
purpose applications, including civilian and military.
The brass outer shells have a nickel-plated surface which
ensures very good protection against most environments.
Alternative protective coatings available are:
– Nickel-chrome offering higher protection against salt
– Nickel-gold
– Nickel-black chrome. After the black chrome treatment,
The shell surface is protected by anodizing which is
available in six colors: blue, yellow, black, red, green,
and natural.

Plastic Materials
A PEEK outer shell is available which offers excellent
insulating properties and is mostly used in the medical
industry. This material is suitable for gas or steam steril-
ization.
Other Metallic Components
In general, other components are manufactured from
brass. However, bronze is used where good elasticity is
required (for example: earthing crown).
These parts are nickel or nickel-gold plated depending on
the utilization.
