Insulator
Technical Description
LEMO uses virgin quality PTFE for the insulator material
of coaxial connectors, which guarantees excellent insu-
lating properties.
LEMO also proposes PEEK (Polyether Etherketone). Its
higher mechanical strength and excellent radiation resis-
tance make it ideal for most applications.
Technical Characteristics
Electrical Contact
Technical Description
The secure, reliable electromechanical connection
achieved with LEMO female contacts is mainly due to
two important design features:
1. Prod proof entry which ensures perfect concentric
2. The pressure spring that maintains a constant, even

Contact Material
LEMO female electrical contacts are made from bronze
(UNS C 54400). Bronze is chosen because of its high
modulus of elasticity, its excellent electrical conductivity
and a high mechanical strength.
LEMO male solder and print contacts are made from
brass (UNS C 38500). Male crimp contacts are made
from brass (UNS C 34500) which is ideal for crimping
onto the electrical conductor.
Conductor retention method
Both male and female contacts are available in crimp,
solder or print versions.
