Insulator
Plastic material used by LEMO for manufacturing insula-
tors is selected according to the electric and thermal
properties required for the various connector types. Char-
acteristics examined for the two connector types are:
– Dielectric strength;
– Comparative tracking index;
– Surface and volume resistivity;
– Continuous service temperature;
– Water absorption;
– Radiation resistance;
– Flammability rating
– Resistance to hydrocarbon.
Mechanical and Electrical Properties
Mechanical characteristics of thermoplastics, such as PA
6.6, and PEEK, are improved by the addition of glass
fibres. By adding glass fibres in the resin the performance
of this material (mechanical strength and radiation resis-
tance) is enhanced and water absorption rate is reduced.
From an electric point of view, the addition of glass fibres
improves dielectric strength.
Selection of the insulator
A number of thermoplastics have common characteristics,
some of them are identical with other insulating materials.
In this case, the insulator material is selected according to
the specific difference in features to provide all the required
parameters for the given type.
Technical characteristics
Note: values of insulation resistance between contacts are given on page 177.
